5 Best Wind Generators For Sailboats (2024)

Last Updated by

January 2, 2024

Wind generators, also known as micro turbines, have come a long way since their first appearance on the cruising scene back in the 1970's. Loud, relatively low output and large bladed, these forerunners of the modern day wind generators were both a mechanical marvel and a source of constant consternation. They were basically a small automotive alternator encased in an aluminum housing, with little thought into aesthetics or longevity. Cruisers equipped with an old Windbugger or K.I.S.S. wind generators come to mind as the loud boats in the anchorage no one wanted to be around.

As we all know, there are very few, if any, automotive products that last very long in a marine environment. A large stock of spare parts had to be stored in case of breakage, and daily maintenance consisted of checking the bearings, monitoring the voltage vs. wind speed for signs of decreased output, and rotating the blades into the wind when the boat position changed.

Today's best wind generators boast such features as CAD designed, self-feathering composite blades that are whisper quiet, brushless magnetic alternators, automatic braking and over-charge protection. Boxy aluminum housings have been replaced with sleek, carbon fiber and fiberglass nacelles.

While you may spend a small fortune on a wind generator that has all of these features and more, you can also opt for more budget friendly models, readily available from Amazon, Home Depot and other on-line retailers. The best wind generators are usually the most expensive, but when you are looking at the lower cost models, remember to add in the cost of wiring, mounting hardware, remote monitoring stations and installation, should you choose not to do the work yourself. Not all wind generators are purpose-built for the marine environment. Buyer beware: a turbine designed for the hobbyist on land will not stand up to the rigors of an offshore passage.

Table of contents

As with any mechanical device you are researching, it is a good idea to learn some of the terminology associated with the product. Not all of us know the meaning of 'swept area', 'power capture' or 'yaw error'. Likewise with the electrical side of the wind generator. Learning about output wattage, amps, and microprocessors can seem like a daunting task, but it is necessary to know these terms before you shell out hard earned cash for a quality wind generator.

Some features of wind generators, such as weather-proof coatings and low-noise operation, are common to all makes and models. The use of rare earth elements like Neodymium, (Nd2FE14B, used in magnetic rotors), can add hundreds of dollars to the price of some of these wind generators, but defiantly do add to the overall dependability of the unit.

Some of the more desirable things to look for in a wind generator are:

• Ease of Operation

Also known as plug-n-play, the simpler the set-up, the better. Choose a model that has built-in controllers, that ???makes for less complicated wiring runs. A remote monitor is handy to check on the status of the charging system without crawling into the battery room, or looking up to see if the blades are still turning. If you are ordering your generator and having it shipped, ask your salesman to be sure it has detailed assembly instructions and perhaps an owner's manual in either DVD or booklet form.

• Low Cut-In Speed 

Wind generators work best when the blades are humming along in 20 knots of wind, but that's not always the case. Low cut-in speed means your batteries are getting a charge in the lightest of airs, if only a trickle charge.

If you happen to be ashore when the wind kicks up, you don't want your turbine to spin wildly out of control. Some generators feature a type of automatic speed governor that slows the blades down before they self destruct. Back in the day, you had to pull down on a cord to apply the brakes, then climb up the mast or mounting pole and manually tie off the blades.

• Over-Charge Protection

A 'brake' also kicks in when the batteries are nearing or at full capacity, to prevent overcharging. Some controllers slow the rotation of the blades, others 'dump' the excess power generated through a resistor and heat sink. Wiring an in line reset-able fuse can prevent damage to your batteries should a malfunction occur within the charging system.

• Portability

If you are one of those part-time sailors who cruises for a few months, then dry-docks your vessel for the off-season, choose a light-weight portable wind generator you can set up at home to off-set your electric bill. In case of a hurricane or other emergency when there is no power for days at a time, your wind generator can power cell phone chargers, laptops and rechargeable battery stations. Removing your wind generator and locking it away in the cabin also deters thieves. Portable wind generators that are light can be mounted on higher surfaces without worrying about upsetting the balance of your boat. The heavier the generator, the lower it should be mounted, allowing for safe passage under and around those spinning blades, of course!

It is also a good idea to know your boat's needs and desires before settling for a low cost, low output wind generator. Everything that runs off a battery, including the DC to AC inverter, should be listed, along with their amp/hour draw, to determine how much power you will need to generate. Compare your toys with your reserve amps of your house battery bank. Do you just have a few LED bulbs and a masthead light to run at anchor? Then you can get by with a low output generator. Are you keeping a keg cooler, stereo, disco ball and Netflix going all night? When underway, are you powering SSB, weatherfax, VHF and radar? Then you need a rack full of batteries, and a wind generator with the capacity to keep them topped off.

Speaking of batteries, make sure the wind generator you purchase can charge all the different batteries available. Even if you only have wet-cell lead/acid marine batteries now, you may upgrade to AGM, Gel or even LiFeMgPO4 (Lithium Iron Magnesium Phosphate) batteries in the future. Some wind generators and their controllers are not advanced enough to charge these newer power sources.

Unless you are well versed in the application of electrical theory and DC current, you probably don't know much about wire size and current loss. Even the best wind generator will not function as advertised if the power can not get from the blades to the battery. If you have a long run from your generator to the battery bank you intend to charge, make sure your wires are correctly sized to prevent line loss from resistance and over heating. Most installation manuals will have a wire chart included for DIY installations, and there is always a help line to the manufacturer.

Here are four out of the dozens of wind generators out there that have positive reviews and some of the most desirable features.

1.) Superwind 350, 353

This German manufactured turbine features their patented Auto-Feathering Overspeed-Avoidance System. This is basically the same method a helicopter uses to gain lift, and settle back down. As the wind speed reaches 25 knots, the blades 'feather', or dump air, making them less efficient, and slowing their speed. As the wind lessens, the blades re-pitch, becoming more efficient. This action delivers a steady flow of charging current to the batteries, without going into a shut-down mode to prevent overcharging, as some models do. The Superwind generators also can be combined with solar panels and conventional diesel generators. The Superwind generator family also uses a brushless A/C stator for maximum control of noise and radio interference while the unit is producing power. Two sets of bearings in the 350 make for smoother operation and overall longer bearing life. Available in 12v, 24v, or 48v outputs. At close to 30 lbs, these units are well built and dependable. With a price tag right around $2,700 for the Superwind 350 kit, you can expect German Engineering at it's finest.  https://www.superwind.com/superwind-350-353/

2.) Automaxx

The Automaxx line of wind generators comes in 12v, 24v 48v models, in outputs from 400w up to 1500w. Survival wind speeds are listed at 110mph, but we hope you would never have to put that spec to the test. With very low cut-in speeds of less than 6mph, you will get charging amps on the slightest breeze. All their models come with auto-braking and manual braking system protection, over charge and over-speed protection. The 3600 rotation of the power head keeps the unit into the wind, even when you are docked or med-moored. Simple plug and play setup with an internal MPPT (Maximum Power Point Tracking) charge controller makes the DB400 an easy to install unit, while their other models feature a remote charge controller. Works well when combined with solar chargers. At 16.75 lbs., it is lighter in weight than the Superwind, and it's seven times less expensive at around $400.00 for the DB400.

3.) MarineKinetix MK4

One look at this brand's marketing home page is like an advanced course in wind generator physics. The list of specs for it's models is truly impressive. Not only do they boast all the latest technologies featured in their product, they explain all the scientific jargon they use in terms us simple sailors can understand. They have been providing wind generators to the sailing community for 8 years now, and have a devoted following.

If you need to know the difference between $400.00 wind generators and $1,800 units, check out the product overview section of their website.

The MarineKinetix brand has the the industries best 3 year limited warranty, so they must be pretty sure about their product.

The 12v models of this brand are currently out of stock, due to parts supplier back-orders, but if you are in the market, there are plenty of 24v and 48v units in stock.  https://store.marinebeam.com/marinekinetix-mk4-marine-wind-generator/

4.) Rutland 1200

One of the quieter wind generators out there, the U.K. made Rutland has a long track record of dependability and customer satisfaction. A manual switch is used to stop the blades when high wind is expected, there is no auto-brake. The Rutland can be combined with solar panels up to 20A, and can be also be used with deep cycle gel or AGM batteries, and there is a remote digital display available. One of the Rutland's best features is it's Tri-namic Blade profile design, which achieves low start-up speeds, silent operation in any wind, and maximum power transfer from wind to rotor. Overall good performance and features for the $1,600.00 price tag. https://www.emarineinc.com/Rutland-1200-Wind-Turbine

5.) DuoGen-3

Wind generators are a fairly common sight in most anchorages, and towable generating devices have been around for some time. The DuoGen-3 combines the two into one multi-use charging system. Underway, the high strength carbon fiber mast is lowered down to submerge the blades. At anchor, the unit functions like a typical wind generator. The results are impressive. In the water mode, the DuoGen-3 generates 200 Watts @ 16 amps cruising at 8 knots. Wind generators do not do well sailing downwind, so this may just be the answer. Available in 12v and 24v versions. Charging regulators are not included, so monitors and controllers have to be matched to the unit and sourced locally. https://eclectic-energy.co.uk/

Choosing the right wind generator for your vessel should be a pretty straightforward process, once you have an idea of your needs, the area you will be cruising in, and how long you expect to be 'off the grid'. If one generator is simply not enough because of the size of your battery banks and the load you put on them, you may need to purchase a pair of turbines. Customer support and availability of parts may be the determining factor in your purchase. Talk to other wind generator owners, and get a feel for what they have experienced with their current of former wind generators.

Best Boat Generators

The best thing about owning a boat is the ability to travel anywhere you want. Being a boat owner means that you will be enjoying another home that you can use anytime and do whatever you want. Of course, in order to be comfy doing this, you need access to electricity. This is where the best boat generators come in.

In addition, you have to decorate it in a way that fits your personality. You can even add cool decorations to it or even fill it up with full-sized appliances, electronic gadgets, and any other comfortable features present in modern homes. With the best boat generators, you can add to your boat/sailboat and make it as convenient and functional as possible.

With the portable boat generator, you will be able to charge your batteries to keep the fridge running, power the water heater, or any other appliance you have onboard. All the generators listed in this article check all these boxes.

In this article, we will learn more about the top portable generators for boats, their advantages, and how you can make a great choice.

Here Are the Best Portable Boat Generators of 2020

Honda eu2200i inverter generator – best of the best boat generator.

One of the most popular choices with many boat owners and probably the best generator for your boat. You can run most appliances aboard with this boat generator. It is extremely quiet, and it is made by Honda. This is a company renowned for its reliability. Cheaper portable generators exit, but if you are looking for something reliable, quiet, and overall the best unit for your boat, this is the way to go. Also, if you are looking for additional power, you can it hooked up to a second EU2200i.

This unit is also fuel-efficient so, it is kind to your wallet (at least after purchase) and the environment. It can run between 4 and 10 hours on a single tank, depending on the load. This generator is also perfect for applications that run for an extended period of time. That is because it utilizes Honda’s leading inverter technology, which was designed to produce power similar to what you would get from your house’s outlet.

WEN 56200i Super Quiet 2000-Watt Portable Inverter Generator – Best Quiet Boat Generator 

This generator is one of the quietest yet efficient generators on the market today. An impressive aspect of this quiet boat generator is that its noise level does not significantly differ regardless of how much load its caring. 

This inverter generator has a powerful 2,000-watt motor and is very quiet. Its power capacity is suitable for powering light electronics such as TVs, mobile phones, tablets, computers and, of course, charge your batteries. It is also light-weight, just 48 pounds. This makes it very convenient to move, store, and transport. With its 1 gallon tank, it can run for 5 hours at full capacity and 10 hours at minimum capacity.

Also, this portable generator produces “clean power”. This means that it is preventing power drops and surges so you can operate sensitive electronics such as smartphones, tablets, and laptops without damaging them.

Westinghouse Heavy Duty Portable Generator – Best High-Performance Generator

This generator is for the boater who is looking for the most powerful solution out there. He is looking to bring the comfort of this own home on to the boat. This can power almost everything that can be used safely on a boat. With models of this generator cranking up to 15,000 peak watts and up to 12,000 running watts, this generator is something that most people would consider “too much”. The smallest generator of this line up puts out 5,300 Running Watts and 6,600 Peak Watts, which is still plenty if you ask me, but everyone has different needs.

You can fire this machine with ease, considering the fact that it comes with a button that you just push. The gas tank is also huge, with a 6.6-gallon limit. Also, there is a fuel gauge in the tank, enabling you to check the fuel level easily.

The huge gas tank is also a big advantage as it means that the generator can operate for more than ten hours at 50% load. Also, it is highly fuel-efficient and is capable of starting up even when exposed to low temperatures. In addition, the unit automatically shuts off when it detects the oil level is too low or the oil overheats. This prevents damage to the engine.

• Highly Powerful – Boasts of up to 15,000 Peak Watts
• Protects the inner unit with a steel frame
• Start with a push of a button
• Huge 6.6-gallon tank
• Largest Inverter Generator
• Runs for 10 hours with ease
• One of the loudest options

Goal Zero Yeti 1400 With Solar Kit – Best No-Noice, Eco-Friendly, Solar-Powered Boat Generator

The last, but certainly not the lest, generator I would recommend is the Goal Zero Yeti 1400 Lithium Portable Power Station. Obviously, this product is not for everyone, much like an all-electric car. 

The Goal Zero Yeti 1400 is a battery and sun-powered generator. It is a great alternative for the boater that hates noise, is eco-friendly, and doesn’t care about its price tag. This piece of advanced technology is a clean alternative to a 2,000-watt gas-powered inverter generator. It can produce a continuous 1,500-watt output and a surge capability of 3,000 watts. 

If you go for this product, make sure to opt for the solar kit. This will be the solar panel that generates the power to fill up the unit’s battery. For a full charge, it takes about 25 hours from a house outlet or 4.5 hours with the Boulder 100 Briefcase solar panel; with optimum solar conditions.

It might look expensive at first glance, but considering that it can be charged efficiently with the solar panel and you will not have to pay for gas, oil changes, and maintenance costs of a conventional generator, it starts to look more appealing. 

• Eco-Friendly
• Can be used indoors
• Relatively Heavy (72 Pounds)
• Can be charged with the sun
• Lack of mechanical parts means fewer problems and repairs
• Battery degrades over time

What Size Generator Do You Need For Your Boat?

When looking for a boat power generator, it’s essential to think about the size and power of the unit in question.

For boaters who only need to use a few small appliances and don’t have air conditioning on their boat, a small boat generator is just what they need. Smaller, portable generators are a great option for those who are short on space and need to keep their weight low. That said, they cannot power much.

Those with 30-amp electrical systems and average power needs, a 2,000-watt boat generator should be enough. This will start and run some small air conditioning units, and will easily power any other appliance you may want to use. That includes a microwave, which is an electricity pig, and uses a massive 1,000 watts.

Larger boats with bigger electrical systems can also run on a 2,000-watt generator. That said, those with bigger boats should keep in mind that only one air-conditioning unit can run on 2,000 watts at best. A larger, more powerful generator may be needed to fill their needs.

In the end, what capacity generator you decide for your boat is up to you. As long as you consider power output, storage space, and the weight you’ll need, you should be able to choose the best boat generator for the job.

Choosing a Generator for Your Sailboat

• By Ed Sherman
• Updated: November 14, 2018

You can’t take it anymore: Your 1990s vintage cruising sailboat didn’t come equipped with a factory-­installed air-conditioning system or an alternating-current generator to power it and the other AC appliances you’ve brought aboard. Since you’ve owned the boat, though, you’ve turned into a real believer in global warming as you try to sleep through sweaty nights on board, and finally you’re ready to pull out your wallet and do something about it.

So, where do you begin? The first step is to analyze how much electrical power you are going to need. Since your boat had a basic shore-power system when you bought it, you already have some idea of your small-appliance usage, things such as hair dryers, the coffee maker and maybe even a small TV. But now you need to think in terms of running this same gear while at anchor. Additionally, if the standard-equipment shore-power option for your boat at the time of purchase was a 30-amp service, as is most often the case here in the United States, you might discover that it’s inadequate to run that new reverse-cycle air-conditioning system you’re dreaming about.

This is an area where, in my experience, a lot of boat owners go into denial as they discover that more power consumption adds considerable cost. Everything you’ve read about marine electrical systems so far tells you that air conditioning and refrigeration use a lot of power. But how much? The good news here is that these units have become more efficient in recent years and the power needs are not as great as they were when your boat was new. As an example, a modern 18,000 Btu reverse-cycle system from Dometic Corp. will need about 15 amps of AC power to get the job done. A 10,000 Btu unit is going to draw around 8 to 10 amps, depending on your location and whether you are heating or cooling.

Analyze Your Needs

The first step is to do an honest load analysis to see how much electrical power you will need. This is typically measured in thousands of watts, or kilowatts. The operative phrase here is: Don’t cheat. If you want to luxuriate in air-conditioned comfort 24-7 while cruising, it’ll cost you. Unlike powerboats, most cruising sailboats come equipped with liquefied petroleum gas stoves and ovens, so one of the major power consumers (an electric galley) is not a concern here.

All said, you are probably going to be looking at generators in the 4 to 12 kW size range. The typical owner of a 40-something-foot sailboat who wants to power up a reverse-cycle air-conditioning system, small galley appliances, a refrigeration system using either AC or DC power, a water heater and a battery charger is going to want an 8 kW generator. Larger boats that might end up having a clothes washer and dryer, larger reverse-cycle heating and cooling unit and water heater can easily end up in that 12 kW output range. The American Boat and Yacht Council offers a free trial membership with access to the relevant electrical power ­standard (E-11), including a complete load analysis worksheet for those who are so inclined and want a detailed account of their electrical needs. Simply go to abycinc.org to gain access via the consumer section of the site.

A quick way to determine your AC power needs is to look for the mandated label on each appliance. It is required to tell you either the operating voltage and amperage draw or the operating voltage and wattage.

Either way, a simple equation can be applied to get the info you need: Volts multiplied by amps equals watts; or watts divided by volts gives you an amperage value. Add the number of watts each device requires and you will get an idea of what size generator you’ll need. Remember that it takes 1,000 watts to make 1 kilowatt. Understand that this method will actually give you a result that does not take into account the fact that you might not be running all of your appliances simultaneously. The ABYC load analysis method found in the ABYC E-11 standard offers some diversity adjustments that are more conservative and reflective of the real world.

Although modern ­generators are not as sensitive to running with a light electrical load, most installers will tell you that running them at 70 to 80 percent of their maximum capacity is better for the engine. The risk here is carbon buildup in the engine’s combustion chambers if run with a light load for extended periods. So, this is a case where significant overkill is not such a good thing.

Practical Concerns

In addition to the electrical load you need to meet with your new generator, you should also be considering its weight and physical dimensions. Will the generator fit into the space you have available? The units I compared (see “Generators by the Numbers,” page 82) ranged in weight from a low of about 270 pounds for the 5 kW Fischer Panda to a high of just under 700 pounds for an 11.5 kW Kohler. This amount of weight dictates that when installing a generator on a monohull, you’re going to want to keep it on the centerline of the boat. Typically, this works out well because most sailboats built from the early ’90s on will have adequate space aft of the propulsion engine to fit in new generator. Multihulls offer more options on that front.

What might be a concern with the monohull is service access, not only for the generator itself, but for things like the propeller shaft stuffing box and shaft coupling. I’ve inspected many boats where the only way to access a leaking shaft seal was to lift the generator out of the way!

Wherever you end up installing your new generator, you need to be able to gain access to all the service points on the unit.

The physical dimensions of the generator could end up being a game changer too, so you’ll need to measure your boat’s available space carefully and compare that to the specifications for the units you are considering. You will also need to determine whether the unit will fit with a sound shield installed or not. Understand that some of the generators offer a sound shield as an option only. The presence of a sound shield, or your ability to insulate the space where you are going to have this generator mounted, could make a difference not only in size requirements but also noise issues while running.

As an example, comparing a Fischer Panda unit that comes with a standard sound shield, we get dimensions of 23 inches by 17 inches by 22 inches. A similarly rated Cummins Onan unit, which also comes with a standard sound shield, is 26 inches by 23 inches by 21 inches. A Westerbeke with a similar rating but with optional sound shield measures 36 inches by 23 inches by 25 inches. That 13-inch spread in length between the Fischer Panda and the Westerbeke could mean the difference between a doable install in the space available on your boat or not.

Finally, wherever you end up installing your new generator, you need to be able to gain access to all the service points on the unit. Can you get that oil filter off as installed? Can you access and change the water-pump impeller without needing an emergency ­chiropractic visit? These are questions that will need answers.

Power Perks

Several features related to newer generators are worth considering. One is whether the unit is equipped with digital controls that may also allow for self-diagnostics and integration to onboard networking that you or a former owner may have installed on the boat.

From a maintenance standpoint, you’ll also want to know whether the water-cooling system for the engine driving your generator is raw- or freshwater cooled. Raw water might save money initially, but will cost in the long run.

Buyers Beware

I can’t emphasize this enough: This sort of upgrade does not qualify as a do-it-yourself project unless you have ­considerable mechanical skills and experience, and labor will be a major addition to the overall cost of the installation.

Also, when you compare different units, study the supplied components carefully. Does the unit come with a remote display and control panel? What additional parts will you need? These will likely include an exhaust system, starter battery and cables, and raw-water supply hoses and a seacock. And don’t forget about wiring the generator ­into your existing, or possibly a replacement, AC ­distribution panel board. These items can add considerable cost above and beyond the generator prices shown in “Generators by the Numbers.”

If you are planning on cruising far afield with your new generator, you should also think about parts and service availability, not to mention its warranty.

Lastly, if you are planning on cruising far afield with your new generator, you should also think about parts and service availability, not to mention its warranty. As part of my ­research for this article, I looked at units from Cummins/Onan, Fischer Panda, Kohler, Northern Lights and Westerbeke. All five brands have extensive global dealer networks, so ­locating a service center that can help is just an internet search away. As for warranties, I’ve noted them in the “Generators by the Numbers” table. Keep in mind when reviewing this ­information that it is based on likely choices from the ­individual company’s offerings for a boat in the 35- to 45-foot size range. Also understand that the prices quoted are list price. Several of the dealers I spoke with suggested that discounts of $1,500 to $2,000 are quite common. That said, if you spot something you think is a deal, be certain of what you are actually getting, ­especially if it’s at a ­remarkably ­discounted price.

A green alternative

Considering the cost of installing a generator — estimated at $15,000 to $20,000, or possibly more depending on your boat and the power output selected — you might consider some alternatives.

How about essentially silent AC power via a direct-­current-to-alternating-current inverter and adequate storage capacity that relies on the latest high-capacity battery technology?

Marine electrical systems have evolved considerably over the past decade or so, and I’m at the point now where I question the need for an onboard AC generator for most cruisers, though some might still benefit from installing a DC generator to supplement solar-, wind- or water-driven charging solutions.

The current density of high-end absorbed glass mat and lithium-ion batteries has improved by 20 to 30 percent due to their inherent capacity compared to older flooded-cell batteries. They can also be discharged to deeper levels without damage and recharged much more quickly due to high absorption rates. I’m of the opinion that it might be time to look at alternative power if you are willing to spend the kind of money we are talking about with an AC generator upgrade for an older boat.

As quiet as they might claim to be, that incessant drone of an AC diesel generator, not to mention the however faint odor of diesel exhaust fumes, is going to be a reality. It’ll have to run all night if you want that AC keeping you cool.

Instead, you could run the DC generator in the morning to replenish your batteries from an overnight discharge. Or, let your solar panels and wind generator do the job. I like the concept of not having to run an engine continuously to get my AC power.

Hydrogenerator

Hydro generator.

The hydro generation or “creating energy while sailing” function is an automatic feature in all Oceanvolt motors. 

This feature is activated by pushing the button on the Oceanvolt displays for 5 seconds. The display will automatically switch to regeneration mode showing the current generated power, RPM and time until the batteries are fully charged. 

With a normal folding propeller the motor kicks the blades out and centrifugal force combined with the motor controller keep the blades open. The motor controllers tune the system actively at 10 Hz which prevents the blades from closing (too much braking would close the propellers). This is continuous monitoring, the system will adjust the propeller RPM depending on the boat speed. 

The system shuts itself down when the battery is fully charged or if boat speed is too low for efficient hydro generation.

OCEANVOLT SERVOPROP

The patented Oceanvolt ServoProp variable pitch sail drive combines a high efficiency sail drive with the most powerful hydro generator on the market. The unique feature of the ServoProp is the possibility to turn the propeller blades more than 180 degrees. The software controlled variable pitch sail drive adjusts the pitch of the propeller blades automatically so that the power generation and power output are optimal. Combined with uniquely designed blades it delivers optimal efficiency in both forward, reverse and hydro generation. And with the blades set to the neutral sailing position, the propeller creates extremely low drag similar to the drag of a feathering propeller. The benefits of ServoProp include an estimated +30% increase in forward propulsion, +100% in reverse and +300% increase in hydro generation effect.

A normal fixed propeller (that by nature does not have the blades ideally shaped for regeneration) generates less than half the power of ServoProp at a given boat speed. ServoProp is capable of generating more than 1 kW at 6-8 knots. The power generated can be used to power both the propulsion system as well as all the electronics on board without the need to have a separate generator. With this in mind we can definitely start talking about the possibility of a totally self-sufficient cruiser!

The ServoProp is suitable as a propulsion motor for monohulls up to 50 ft & multihulls up to 60 ft. It can also be used as a hydro generator in boats up to 100 ft.

Videos of hydro generation

power created by hydro generation

Oceanvolt systems are optimised for either 2 or 3 blade Flexofold folding propellers & Gori propellers.  Other folding propellers can also be used but they provide 30-50% less propulsion and regeneration power. 

The highest regeneration power is gained with fixed blade & adjustable pitch propellers and also with dedicated systems for hydro generator use, because they allow using a higher pitch/dimension propeller.

The regeneration feature is extremely suitable for catamarans because twin motors means double the energy generation.  Catamarans are also faster, which means that regeneration power capture is higher.

Can You Use Portable Generators for Boats and How?

Thinking of ways to make your boat more energy efficient? Using a solar portable generator could be a great way to do that. Portable generators are small, lightweight, and can easily be stowed on your boat for short trips or long cruises.

They provide an efficient source of power for charging batteries, operating interior equipment such as lights and refrigeration systems, powering laptops and other electronic devices, and even running air conditioning on hot days. Some portable generators can even be hooked up directly to your boat's electrical system, allowing you to power larger appliances and equipment .

When choosing a portable generator for your boat, it is important to make sure it is suitable for marine use. Many generators are designed specifically for marine applications and have features such as corrosion-resistant casings and components, water-resistant switches, and fuel tanks that are sealed to prevent leaks. It is also important to ensure the generator has enough power output for your needs; you'll want it to handle larger loads if you plan on powering big items like air conditioners.

In this guide, we'll discuss how to choose the best portable generator for your boat, as well as the safety precautions you should take when using it. We'll also cover some tips on maintaining your generator so that it lasts longer and operates more efficiently.

Solar for Boats: How To Use A Portable Generator On Boat?

Using a portable generator on a boat can provide an abundance of power for your onboard needs. For example, the Jackery Solar Generator 1500 Pro  is a great choice for powering smaller items like phones, tablets, and laptops as well as mini-fridges, coffee makers, rice cookers, and microwave ovens . The higher-powered Jackery Solar Generator 2000 Pro  can run larger appliances such as air conditioners and refrigerators.

Solar generators use photovoltaic panels to convert sunlight into electricity which can then be used to power various electrical systems on boats, including lights, electronics, and appliances. The solar panels  are mounted on the boat's roof or superstructure, and the generated electricity is stored in batteries for use when the sun is not shining. Some larger boats may also have an inverter to convert the stored DC power into AC power for use with standard household appliances.

Solar generators are good for boats for several reasons:

• Environmental Benefits: Solar generators produce clean and renewable energy, reducing the carbon footprint and environmental impact of boating.
• Cost Savings: The use of solar power reduces the dependence on diesel generators and can also help reduce operating costs and emissions while boating.
• Reliable Energy Source: Boats can generate their own power while at anchor or docked, reducing the need to rely on shore power or generator use.
• Quiet Operation: Solar generators operate silently, providing a peaceful environment compared to the noise of diesel generators.
• Increased Autonomy: Solar generators can provide a source of power for boats that are far from shore or in remote locations, allowing for increased independence and flexibility.
• Improved Battery Performance: Solar generators can also help to maintain the battery's charge and extend its life, as well as provide a constant source of power for battery-powered devices.

Definitely, using solar generators to power devices on your boat is a reliable, eco-friendly, and cost-effective choice.

4 Safety Tips for Using Portable Generators for Boats

Safety should always be a priority as with any type of generator. Not only will these tips ensure the safety of your passengers and crew, they will also help you improve the lifespan of the generator.

Here are the four safety tips you should keep in mind when using a solar portable generator on your boat:

Make Sure Use a Small Generator for Boat is Designed for Outdoors

When choosing a generator for a boat, it's important to consider the environment it will be operating in. On smaller boats, there may be limited indoor space, so the generator may need to be located outside. In this case, it's important to select a generator that is specifically designed for outdoor use.

An outdoor generator should have rust-resistant components, such as enclosures, to prevent corrosion from saltwater exposure and other environmental factors. This will help to ensure that the generator remains functional and lasts for a long time. It should have a waterproof cover to protect the generator from rain and other precipitation. The cover should also allow for proper ventilation to prevent overheating.

Furthermore, it's also important to consider the generator's portability and ease of use. For boating, a generator that is easy to move around and set up can be very convenient. It should also have a compact design that takes up minimal space on deck.

Check Your Manufacturer's Instructions

Because you're dealing with electricity in a naturally wet environment, remaining safe is of the utmost importance. Improperly assembling or using a portable generator that delivers enough current and wattage to power small HVAC units can lead to injury or even death.

Always read your manufacturer's guide and instruction manual to ensure that you're following all safety protocols before attempting to operate your generator. Much like we do at Jackery, we include all the necessary information including troubleshooting guides, safety warnings, and more.

Monitor Generator Temperature Levels

Think of your solar generator as a high-performance race car - just like a race car needs to operate at optimal temperatures to perform its best, your solar generator also needs to be kept at the right temperature to ensure that it runs smoothly and efficiently.

Monitoring the temperature levels of your generator is like checking the oil and tire pressure on your race car before a big race. It's an essential step to keep your generator running in tip-top shape and performing at its maximum potential.

Just like a race car driver needs to keep an eye on the temperature gauge to prevent overheating, you need to monitor the temperature levels of your generator to prevent any damage to its internal components. Overheating can cause long-term damage and reduce the efficiency of your generator, just like a flat tire can slow down a race car.

Don't Let the Generator Get Wet

Keeping your solar generator dry is essential to ensure its longevity and safe operation. Water can cause serious damage to the internal components of your generator, leading to electrical shorts, corrosion, and other issues. This can result in costly repairs or even complete failure of the generator, reducing its overall efficiency and reliability.

To prevent moisture damage, it's important to store your generator in a safe and dry location when not in use. This might mean keeping it in a dry storage area, such as a locker or cabinet, or even bringing it inside during extended periods of non-use.

For added protection, you can also invest in a waterproof cover for your generator. This type of cover will provide a barrier against moisture and other elements, helping to keep your generator dry and protected while in use. A high-quality waterproof cover should be made of durable materials and fit securely over your generator, providing a tight seal and protection against moisture, dust, and other debris.

10 Best Portable Generators for Boat Use in 2024 – Reviews & Top Picks

• Last updated: Jan 03 2024

What if your entire boating experience could be ruined by a single item? When you go out on the water, one of the best accessories you can bring is a good portable generator. This helps to keep your various electronic devices charged, which can boost your safety and your quality of life on the open water.

However, finding a good generator is often easier said than done. If you’re not careful, you might end up with a low-quality generator that can’t keep up with your different devices. And what’s the point of a portable generator if you can’t trust its power and performance?

To help you find the best generator, we’ve put together reviews of some of the best generators on the market. Between our reviews and our buyer’s guide, finding the best generator will be easier than ever!

A Quick Comparison of Our Favorites

The 10 best portable generators for boat use – reviews 2024, 1. wen 56200i portable inverter generator – best overall.

Chances are that you want to get back on the boat as quickly as possible. In that case, let’s cut to the chase: if you’re looking for the best overall portable generator , the WEN 56200i Portable Inverter Generator is our top choice.

We love the versatility of this generator. With the 5V USB port, 12V DC receptacle, and two 3-prong 120V receptacles, you can power just about anything. Speaking of power, you get a lot with the 79.7 cc four-stroke engine than can provide up to 2,000 surge watts and up to 1,600 rated watts, all while keeping you compliant with EPA III and CARB regulations.

Honestly, the only real issue with this generator is the height. At 18 inches, this may be a bit too tall for certain boats but it is still the best portable battery generator for boats we have reviewed this year.

• Versatile receptacles and ports
• Powerful engine
• EPA III and CARB compliant
• A bit too tall

2. Rockpals WCE001 Portable Generator – Best Value

It’s an open secret that boating is a very expensive hobby. It’s good to save money whenever and wherever you can. And if you’re looking for the best portable generators for boat use for the money, then you can’t go wrong with the Rockpals WCE001 Portable Generator .

At only 5.5 pounds, this item puts the “portable” back in “portable generator.” And you can charge plenty of items thanks to four DC 12-volt ports, two AC outputs, and two 5-volt USB ports. Your gear will be especially safe thanks to the short-circuit and overcharged protection on top of the built-in temperature control.

So, what keeps this from being our “best overall” choice? This generator sometimes has trouble charging Apple products. And you can’t always run items while you charge them, which is bad if you were hoping to use your smartphone while it charged. Despite this we think its the best value boat generator on the market.

• Lightweight
• Short-circuit and overcharge protection
• Temperature control
• May not charge Apple products
• You may not be able to charge and use items at the same time

3. Honda EU2200i Portable Inverter Generator – Premium Choice

Sometimes, you want the best brand names that money can buy. Are you on the lookout for a truly premium brand of portable generator? In that case, we recommend the Honda EU2200i Portable Inverter Generator .

This is a surprisingly quiet generator, typically running between 48 to 57 dBA, although some users dispute this (see more below). And you get plenty of power thanks to 2,200 watts. If you need more power, you can actually use a special cable to attach two of these generators. Finally, we loved the fuel efficiency: a single gas of tank can get you 4.0 to 9.6 hours of use depending on the power load involved.

However, this premium choice isn’t perfect. In this case, several users reported that it is louder than advertised. And you may need to buy a separate funnel to pour engine oil without making a mess.

• Quiet design
• Can double power with a second generator
• Fuel-efficient
• Too noisy for some users
• Separate funnel may be required

4. Durostar DS4000S Portable Generator

The Durostar DS4000S Portable Generator did not manage to crack our “top three” for portable generators. Nonetheless, this a solid model that is suitable for many of your boating needs.

With its 4,000 peak watts and 3,300 running watts, you get a lot of power from the 208cc OHV engine. You get several outlets here, including two 120V household outlets and a single 20V 30A twist lock outlet. The fuel capacity (3.96 gallons) is pretty solid and the entire thing is EPA and CARB compliant.

What’s the catch? Some users report that the fuel gauge isn’t very accurate. And others report that the pull-start mechanism can be difficult to get started.

• Strong power
• Versatile outlets
• Good fuel capacity
• Compliant design
• Inaccurate fuel gauge
• Difficult pull-start mechanism

5. A-iPower SUA2000iV Portable Inverter Generator

The A-iPower SUA2000iV Portable Inverter Generator was very nearly our choice for best premium portable generator. And depending on your needs, this particular generator may be a perfect pick for your next boating adventure.

The generator puts out 2,000 peak watts and 1,600 running watts which is good (though not great). You have plenty of power options thanks to the two 120-volt outlets as well as the 12-volt multi-function port. At 50% load, you can look forward to 9 hours of runtime, all while enjoying features such as built-in fuel gauge, indicator lights, and overload alarm.

As usual, there are a few downsides you should be aware of. As with most gas-powered generators, this is going to require more maintenance than a fully electrical model. And at 50 pounds, this might be a tad too heavy for service as a portable generator (though we liked the handles).

• Good power output
• Multiple outlets and port
• Good runtime
• Extra features like fuel gauge and indicator lights
• Extra maintenance required

6. Flashfish Portable Power Station

Still on the lookout for a good budget portable power generator? In that case, the Flashfish Portable Power Station may be worth a closer look.

On top of its solid price, this generator provides a reliable 150 watts of sine wave output. And at only 4.5 pounds, this portable generator is truly compact. And there are many power output options, including two 12-volt DC ports, two 110-volt AC outlets, and three USB ports (including two designed for double-speed quick charging). Finally, the LED screen is a perfect way to keep an eye on your generator’s power and the power of your attached devices.

What’s not to love? According to some users, it is difficult to return this product if it should malfunction. And some of the cooler accessories (like a solar panel to help recharge the generator) are sold separately.

• Sine wave output
• Lightweight and compact
• Multiple power output options
• Convenient LED screen
• Difficult to return
• Better accessories are sold separately

7. Yamaha EF2000iSv2 Portable Generator

The Yamaha EF2000iSv2 Portable Generator is not as good as many of the models we tried. But it’s not nearly the worst. Ultimately, this portable generator is strictly “middle of the road” in terms of quality and features.

There were some things we liked, including the 2,000-watt AC output and the quiet muffler that brings the noise down as low as 51.5 dBA when you’re operating at 25% load. It’s also CARB compliant, but there are a few things you need to watch out for.

Specifically, the oil spout is very difficult to access. This alone makes the oil very difficult to fill. And the generator must ideally be level during use–not a great option when you’re out on the water!

• Decent power
• Quiet operation
• CARB compliant
• Oil spout difficult to reach
• Must be level for optimal use
• Difficult to fill the oil

8. Rainier R2200i Portable Inverter Generator

When it comes to our review roundup, there are always winners and losers. Unfortunately, the Rainier R2200i Portable Inverter Generator falls firmly in the “loser” category.

There are some things to like, including the 2,200 peak watts. You can get up to 13 hours of runtime from the 1.3-gallon fuel tank, and it’s pretty quiet (as low as 52dBA). But there are quite a few issues to contend with.

The instruction manual is confusing and sometimes references other generators that don’t exist. Additionally, it comes with nothing to help you check the oil levels or keep track of service intervals. Finally, some users report the manufacturer is slow to respond to customer concerns.

• Bad instructions
• No way to check oil out of the box
• No way to track service intervals
• Bad customer service

9. Generac 6866 iQ2000 Inverter Generator

The Generac 6866 iQ2000 Inverter Generator is one of the most expensive generators on our list. You might expect solid performance and features for this price. Unfortunately, you may end up very disappointed!

The max AC output of 2,000 watts is good, if not great. And we liked the intuitive features such as the PowerBar and PowerDial. But many other features disappoint, especially at this price point.

Some users received generators that were broken or otherwise missing parts. The engine tends to sputter, and you can really smell the exhaust. Finally, it tends to stall out during use, especially prolonged use.

• Convenient PowerVar and PowerDial
• May arrive damaged or broken
• Engine sputters
• Prone to stalling out

10. AIPER Portable Power Station

The AIPER Portable Power Station sits at the bottom of our list. Unfortunately, that’s not a coincidence: this is one of the worst portable generators for boating.

As usual, there were a few things we liked. That includes the lightweight (3.86 pounds) design and the 12-month “worry-free” warranty. But much of what is good about this generator is outweighed by its negative qualities.

The charge rate from the lithium-ion battery is fairly slow. And it shuts off after about 15 seconds of inactivity, which can be fairly annoying depending on the situation. On top of that, the LCD screen is quite fragile and the company offers poor customer service.

• Good warranty
• Slow charge rate
• Shuts off too quickly
• Fragile LCD screen

Buyer’s Guide – Choosing the Best Portable Generators for Boat Use

Thanks to our reviews, you might already be ready to snag the portable generator of your dreams. However, you may still have a few burning questions. And we’re here to answer those questions as part of our in-depth buyer’s guide.

Whether this is your first generator or you are a generator veteran, this buyer’s guide will help answer your biggest questions. And once you’ve completed this guide, all that is left to do is hit that “order” button and wait for your new portable generator to arrive!

Preparing Your Generator

You might have used a portable generator for other hobbies such as camping. If that’s the case, you might imagine that a portable generator for your boat is a real “plug and play” affair. In reality, there are a number of factors you need to consider when preparing your generator.

The biggest step is “marinizing” the generator. Don’t worry: that’s just a fancy word for making sure your generator is more suited for use on the water. For example, if you’ll be operating in cold conditions, you may want to put lanocote or Tefgel on your fastener threads to keep them from freezing over.

Additionally, you may want to cover the generator exhaust area in rust-resistant, high-heat paint. This ensures that it will still look good after a few years of use.

The final step to marinizing your generator is putting some kind of soft seal on everything except the muffler. This helps to provide an additional layer of protection (quite literally) on the generator so that it can withstand almost any conditions.

Mounting the Generator

Shakespeare’s Hamlet famously asked himself, “to be or not to be?” But before you go boating, you need to ask yourself a bigger question: to mount or not to mount?

On paper, the whole purpose of a “portable” generator is that it’s…well…portable. Nonetheless, you might have an easier time accessing and using this generator if it is mounted in some way.

Generally speaking, we don’t recommend permanently mounting the generator. Instead, you can non-permanently mount it to the deck for ease of access. Ideally, you should mount it in such a way that you minimize your exposure to any unwanted exhaust.

When you’re done with the boating excursion, simply put the generator into storage. For more tips on how to do this, check out our storage recommendations below.

Grounding Your Generator

Some generators are designed to be grounded to the earth before you use them. You might think there is no way to use such a generator on a boat. But with a little ingenuity, you can make it happen!

If your boat needs this kind of grounding, you can simply plug it into a shore power connection on the boat. Before doing so, though, you need to make sure that both the generator and the boat in question support this feature.

For maximum ease of use, you can simply snag a generator that doesn’t require grounding. And that’s a good example of a feature that may well be worth paying a few extra bucks for!

Fuel Considerations

Some portable generators run off of fuel. While this is a great way to provide additional power to the generator, it does bring a few major safety concerns for you to consider.

• Never refuel your generator on the boat . In the event of an accident, you could cause serious damage to your boat, your body, or both. To minimize the chances of unwanted ignition, you can simply refuel the generator outside of your boat. This is easy enough considering that these things are portable!
• Avoid using the generator in an enclosed space . When the generator is fueled up, you can technically run it anywhere on the boat. But some areas are more dangerous than others. If you use the generator near doors, hatches, windows, or vents, you might accidentally fill the cabin with carbon monoxide. And while a good carbon monoxide detector can mitigate this risk, it’s good to play things safe from the beginning.
• For added safety, be sure to inspect your generator for leaks before taking it out on the water . And make sure that you and all of your passengers understand the symptoms of carbon monoxide poisoning in the event that your detectors are faulty.

Safe Storage

A portable generator is great for a day or night out on the boat, but the generator was never designed to stay on the boat. When you’re not using it, you must keep the generator in storage. And there are a few safety tips you need to follow when doing so.

Place the generator in a locker, and make sure the locker has been drained beforehand. Additionally, the locker should be free of any other anchors, tools, mooring pins, and especially fuel. If you put the generator in a locker crowded with these items, then all it takes is a single spark to start a catastrophic fire.

One of the goals of this storage method is to protect your generator from moisture when it’s not in use. But you can take a few easy steps to protect the generator during use as well. This includes building cowling to protect the generator from the water and using rubber mounts for additional protection.

Getting Enough Power

One topic that our reviews frequently touched on was the power output of the different generators. But do you know why this output is so important and how to identify the amount of power that you really need?

It all comes down, of course, to what you are trying to power. If you mostly want to charge phones, tablets, and computers, then a generator with an output of anywhere between 1,600 and 1,800 watts should do the trick. But if you’re hoping to power something larger (like major appliances), you may want a generator with an output of at least 2,200 watts.

While we’re at it, don’t forget a simple rule: all of those little devices add up. While a single phone or laptop doesn’t require much juice, attaching several items to your generator all at once will create a larger drain on your power. If you expect to plug in many different items all at once, it’s safest to go with something that has enough power.

Better to have too much power and not need it than to need extra power and not have it!

Ready to buy your next portable generator for boat use? We hope that our reviews and our buyer’s guide has made your decision easier. If you’re still on the fence, though, we may be able to help you out by answering a final question: which were the generators that we liked the best?

When it comes to the best overall choice, we went with the WEN 56200i Portable Inverter Generator . It’s perfect for your next boat outing, and is also a real game-changer when it comes to camping.

Are you boating on a budget? The Rockpals WCE001 Portable Generator is a great choice for any budget, and it performs as well as many more expensive options.

But just as different boats call out to different handymen, different generators may be more suitable to your needs. Only you can decide which generator will help power your next outing. But between our reviews and our buyer’s guide, you can rest assured that you’ll ultimately make the right choice!

portable generator on 30ft sailboat ?

• Add to quote

This will be my first hot Florida summer as the owner of my (new to me)Hunter 290 coolchange . Outfitted with AC she is dry and cool while conected to shorepower. It would be nice, to be able to run the AC while out on the hook when it's getting too hot. A friend mentioned to try a portable generator like the HONDA 2000, placed on the swimplattform and connected with a special cable into the shore power connector on the back of the boat. My 10.000btu AC seems to draw ~ 9AMP and the generator is rated with 13.7 AMP ( 17AMP max ) I assume from the electrical side that could work. Has anybody experience with a scenario like this? Any thoughts, hints advice for or against it. I could borrow a friends generator to try it out, but I would like to hear your opinions first, before I go out, buy the cable ...  

humm First thing that comes to mind is that a honda generator may not be suitable for the marine environment which can be quite harsh. That being said, I have heard of many others who have done this.  

caution... just be careful of portable generator exhaust fumes. even on the stern of the boat, breezes can swirl, eddies can form... I know it sounds obvious, but just be sure there's no chance of exhaust anywhere near ports, vents or intakes.  

I have used the Honda 2kw generator for years in a marine environment. None better, IMHO. Assuming it can handle the load, a Honda generator is the best.  

I'm personally not a fan of using a generator on a sailboat. They are noisy, heavy, and they require lots of fuel, if you're to use them for any significant period of time. The warnings about the exhaust are quite good, and I'd get a carbon monoxide detector for your boat's cabin just in case, if you do decide to get a generator. You might want to look into using natural cooling methods when you're out at sea or at anchor, rather than a generator. Wind scoops, awnings and open hatches can do a lot to cool down the interior of a boat without requiring any fuel.  

sailingdog said: I'm personally not a fan of using a generator on a sailboat. They are noisy, heavy, and they require lots of fuel, if you're to use them for any significant period of time. Click to expand...

No personal expereince with a generator on board, but two comments. First would the generator be exposed to immersion in salt water due to the inevitable careless powerbioat wakes? Tha could be an issue even for electrical products built for marine service. Secondly, you might consider the reaction of th epeople sleeping (or trying to sleep) in the v-bearth of the boat anchored immediately behind you. You may not be able to hear the generator in your v-bearth, but they may feel they are sleeping with it. Sound carries exrtremely well over water, even a normal voice conversation can easily be overheard...  

Honda I Is A Great Choice. I Have One For Years 15 Hours On One Gal. Of Fuel (gas) Noise Is Very Min. And I Use It During The Day For Recharging Batteries Vs. The Old Perkins. The Average Life Of Honda Gen. Is Around 10 Years On The Sea With Proper Maintenance. Good Luck. S/v Lady Lena Moody 425 __/)_  

Florida summers can be brutal when sleeping (or trying to) onboard w/o AC. I can see your reasoning behind utilizing the amenities you have and think generators are perhaps the most popular means of powering AC when away from dock. With that said, my personal experiences of generators above deck are negative, at best. Naturally, this view may be bias, since we mostly sail in New England waters, but regardless of make - Honda or otherwise - generator noise is a major sound pollution nuisance. If designed by the boat mfr. to be below decks, in a properly ventilated and sound insulated compartment, such as found in well designed motor yachts and larger sailboats, the noise is sometimes tolerable. Every overnight anchorage we've ever spent time in with a neighboring boat with an on-deck generator, has been the scorn of the anchorage. Above deck generator noise is a huge problem. However, if you want to be despised by other cruisers during those steamy summer nights with everyone's hatches open, then go for it.  

Generators that seem tolerable during the day will often be not so tolerable in the deeper quiet of the night. Some generators are quiet enough that the wet exhaust is the only sound you hear, but that rhythmic splash all night long will keep others awake. The Hondas, while quiet, may not seem so at 3 am (to others, anyway). Even here on the Northwest coast, we get hot, clammy nights at times, but thankfully overnight generator operation is a rarity, even among powerboaters. Using windscoops, ventilators and strategically oriented hatches to maximize natural ventilation and cooling worked for us in the Caribbean. Of course it helps to have reliable tradewinds!  

some RV generators like Onan are even quieter. Approved by state parks and such, but I don't know if they make them small enough to be portable.  

Honda 1000/2000/3000 EU series The super quiet EU series is great. It is not designed for salt but handles it well if you don't dip it in salt and expect it to do with zero care/maint. The RV crowd loves tham and you can parallel two for double output. I have two 2000EU and one 1000EU. I run the two 2000's togeather to power a small welder for work on our steel boat. The 1000 is the boat's house generator because almost anyone can carry it up/down the companionway. At 48lbs the 2000 is VERY portable but is not lightweight. Most guys could walk down the dock with a 2000EU in each hand. That's 4000watts!! Need to check the starting current on AC to see if any given generator will start it. Often a gen will run something but not be able to start it. Mayberry is consistently the best place to buy or at least the price you quote to your dealer to keep him honest. http://www.mayberrys.com/ Yamaha has started up a line of competing super quiet's and they have some nice features like an easy drain on the carb bowl that I wish the honda had. Good Luck...!  

I'd like to add my opinion that running a generator on deck in an achorage will bring you scorn and contempt from most of your fellow cruisers. If your noise is annoying me you will get a visit from me and I will politely ask you to cease and desist. I love to anchor out because of the silence and serenity. If you feel you have to have A/C, please stay in a marina or stay at home. Paul  

If you feel you must have such silence and serenity I would suggest staying out of most anchorages. Many are near populated areas with noise from houses, traffic, even sea and air traffic (anchored off the end of a couple military runways in FL). At night I would not like the added noise from boats, be it talking, water running, or generators but if I had a real problem with it I would leave, particularly if they were there first.  

I don't believe the Honda will handle the start up loads of your AC. Why not borrow or rent one and try it out before investing in one. Two other points: 1. The Hondas are wonderful little on deck generators and can really help keep up your batteries and handle minor chores in the DAYYIME! They are quiet for what they are but that is still NOISY both on board and to others. 2. Try a couple of HELLA fans and make sure you have screens and you'll be fine once the sun goes down. A bimini with side shades or a deck cover makes things more tolerable during the day....or you could go to the Mall!  

RV forum for answers on AC and generators. I am not a fan of generators in a anchorage and trying to run all the comforts of home, but if you must, ...... the Honda EU series is super quiet and you are being considerate of your neighbors to use one. The Honda 2000EU may very very well run/start one of the very very small household window units, but I am not so sure about the standard hatch mounted AC's. It would be easy to call tech support at the AC manufacter and then talk to Honda or Maryberry about the anticipated load. Also, putting the question out on an RV forum would probably get you an answer very quickly. It is what they do every day !!!!!  

Thank you all for your opinions! I have tried it out with a friend's generator: The Honda 2000EU indeed handles the run AND startup of my AC. I am well aware of the noise pollution and promise to be very considerate on the rare occasions I will use the on-deck generator. Many powerboaters here in Florida are using them and not always they try to be careful to minimize their impact .... I think, trying to stay downwind and seperated from the crowd ( if any ) could be a compromise. To all sailors from other areas: The unique situation we have here in the Gulf of Mexico is to have very high water temperatures as well. Of course it could be hot and steamy in other parts of the nation but if you add almost 90 degree of water temperature you feel like in a nice baking oven with upper and lower heat on ... Again, thanks to everyone and fair winds and always some water under your keels. Volkhard  

I've used the Honda 2KW for 3 years (48 lbs) and they're great for powering my 5200 btu AC unit while on anchorage. Here in Florida we have not only mosquitos but these pesty, tiny no-see-ems that'll make your night absolutely miserable (so much for the windsock and netting approach). You should see what the intial amp draw is on the 10K btu unit. It may be more than double the running load. The Honda 2KW is also good for charging all batteries at the same time saving engine hours. Set the Honda 2KW on ECO THROTTLE and they're super fuel efficient - a good 8 hrs plus on one gallon! Noise wise they're very quiet. That's what got me interested in them initially. You can carry on a normal conversation with the unit running between the two people. I've never had anyone complain of the noise at night. But I've heard other gen sets that are much loader. Just be cautious of the ventilation and may wanna consider installing a CO2 detector to be safe. Let me know how it works with your 10kw unit.  

I believe surfnrg means a CO detector...  

I have lived on a sailboat since 1999, and the Honda 2000 watt generator is awesome! It's quiet, 17 hours on one gal of gas, and small and portable.  

I've never used a generator on boat...internal or external. I'm about to charter a 42 footer with a generator. We don't run the AC at night and historically we've had to run the engines for a couple hours per day or just to get to our destination without having to tack all over the place. I assume that charges the batteries. What's the purpose of the generator and how/when would I use it?  

my honda 2000eu is awesome--6 yrs of abuse in marine environment still working smoothly and quietly---btw--mine never got 17 hours on one gal of gas--they run 8-10 hours on 1.5 gal..lol....i use mine in my cockpit--formosa 41 has huge places to use--lol----for a/c might want 2 of them!! i donot use a/c ever---i get really good airflow without need for artificial environments...but that is just my preference......  

I saw a boat in marathon that had a honda hanging about 12' off the deck  

Noise can be difficult to judge. Our Espar heater seemed loud, we could hear it in the boat, when installed but even 5 knots of wind would cover the sound. We had it running for days before it was calm enough that others figured out we had a heater. Best to not run anything at nite if it is calm and the anchorage is so remote there are no land or ocean sounds. Then sound really travels. I end up not sleeping because all the critters can be heard. Nothing gets me up like hearing a large mammal breathing by my boat. Can't help it, too much camping where anything that large in camp is trouble.  

Had a honda for 20 years they are quite and reliable last around ten years even if abused they usually fit nicely right in front of the mast. Never had a carbon monoxide problem but now that they have good carbon monoxide detectors I have two on my 47 foot sloop just in case.

6 Best Generators to Take on a Boat – Your Easy Access to Power

When you’re out in the water, it doesn’t mean that you have to sacrifice having easy access to electrical power. Generators have come a long way in the last several years, allowing you to have all kinds of options. But depending on your boat, there are many things you need to take into consideration. Smaller boats probably won’t be able to handle a permanently installed generator. Which is why there are all kinds of smaller, more portable options out there. Noise is also a big consideration when you’re on a boat and have limited space. Inverter generators are quieter and more fuel-efficient, making them the unit of choice for use on a boat.

To find the best generator for a boat out there, we rated the top generator models by engine power, rated/maximum output, fuel tank capacity, noise level, weight, and portability. We also noted whether the generator had issues with the pull-starter, carb clearance for storage and oil fill. Engine power is an important consideration because you need to know that the generator you choose can keep up with the demands of whatever job you need it to do. With marine generators, it is especially important to note fuel tank capacity, because you don’t want to run out of fuel in the middle of nowhere. Since space is at a premium on boats, you will want to make sure the generator’s noise level stays at a comfortable purr, so it won’t interfere with any of your activities. Weight and portability to carry the generator to and from your vessel have also been considered. Each extra pound aboard a vessel will affect its speed and buoyancy, so it’s important to know your vessel’s capacity and consider the weight of the generator.

We searched out customer and expert reviews and product specs for each of the top generator brands and have listed our findings in the table below. The generators have been listed according to our ranking. Included also is a detailed review of each product , and a buying guide that we hope will clear up the most important things you need to know before taking a generator aboard.

Top 6 Generators for Boat Review 2024

Briggs & Stratton P2200

• Peak/rated watts: 2,200/1,700
• Engine: 110cc Briggs & Stratton OHV
• Fuel tank: 1 gal.
• Runtime: 8 hrs. (25% load)
• Outlets: (2) 120V Household, (1) 12V-5A, DC Outlet with USB Adapter
• Start type: recoil
• Noise level: 59 dB(A)
• Warranty: 2-year limited

The Briggs & Stratton P2200 functions as well as an ordinary generator that keeps up with the wattages coming in at 2,200 starting and 1,700 running watts. It does weigh in at the heaviest of all of them, 55 pounds, which is a good 11 pounds heavier than the Yamaha. This would make a significant difference to practical portability for people with back problems or tendonitis.

Some people say they liked the handle, others said the reviews of the 3,000 were mixed in with the 2,200, which confusingly stated that it contained a suitcase-style handle and wheels for east of portability. There were also complaints that the noise level it claims is not what they measured. Many users stated it is louder than the other varieties of generator, for example, the Honda. This would be especially problematic on a boat as sound is multiplied and carried easily over water.

Despite this, there is a switch for turning on “Quiet Power Technology,” which is extremely effective at limiting noise, but it cannot be used at capacity in this mode, although it does save on fuel by reducing RPMs. The PowerSmart mode adjusts the engine speed based on the electrical load.

Some people had difficulties with starting the Briggs-Stratton generator unless it was used quite regularly. Even then, its start is not easy – taking four pulls, a departure from the rest of the pack that start easily with one.

There is a handy LED light system to alert you of output, low-oil and/or impending overload. Also, it does have parallel capability to hook up and combine the power of two units together if you need more power.

• Fuel efficient
• Parallel outlet
• Two-person handle
• Flexible outlets
• Not shipped to California
• Lacks gas gauge and fuel shut-off valve
• Louder than claims
• Heaviest of all
• Our 9 pick for the: best 2000 watt generator
• Our 3 pick for the: best briggs and stratton generator
• Our 8 pick for the: best quiet generator
• Our 1 pick for the: best generator for tailgating

Honda EU2200iTAG 2200-Watt 120-Volt Super Quiet Portable Inverter Generator with CO-Minder

• Peak/rated watts: 2,200/1,800
• Engine: 121cc Honda GXR120
• Fuel tank: 0.95 gal.
• Runtime: up to 8.1 hrs. (25% load)
• Outlets: (1) 20A 125V Duplex, (1) 12V 100W (8.3A) DC
• Noise level: 48 to 57 dB(A)
• Warranty: 3-year residential and commercial

While both are quiet generators , it is quite possible the Honda EU2200i is quieter than the Yamaha. The EU2200i operates at 48 to 57 dBA, which is less noise than a conversation in held in “inside voices.” If you are on a boat, it will be even quieter on Eco-Mode, and should not disturb anyone in nearby. The Honda can go from 4.0 to 9.6 hours on one tank of gas, depending on the percentage of load that it is required to power at any given time. This model is an upgrade from its predecessor, which went from 1,600 running and 2,000 surge watts to 1,800 running and 2,200 surge watts in the new model.

It also has a new feature: the fuel shut-off switch, which, as previously stated, allows the carb to run dry so that no buildup occurs to interfere with the ignition in the future. Another update is the oil drain, which now has been fixed so that it no longer spills, but instead runs into the drain pan where it is supposed to go. There is also increased ventilation to avoid overheating the front panel.

The Honda EU2200i weighs 45 pounds without fuel, still light enough to carry easily thanks to the contoured handle. The plastic covering eases the movement of the machine alongside your body as you walk. One last thought: Honda has excellent customer service, readily available parts and many locations throughout the U.S.

• Extremely quiet
• Reliable technology
• Fuel shutoff allows carb to run dry
• Good warranty and customer service
• One-pull start
• No fuel gauge
• Less runtime than the competition
• Our 5 pick for the: best 2000 watt generator
• Our 3 pick for the: best honda generator
• Our 2 pick for the: best quiet generator
• Our 5 pick for the: best generator for tailgating

Champion Power Equipment 200961

• Peak/rated watts: 2,500/1,850 – gasoline, 2,500/1,665 – propane
• Engine: 79cc, 4-stroke, variable speed
• Fuel tank: 1.1 gals.
• Run time: 11.5 h – gasoline, 34 h – propane (25% load)
• Outlets: 120V 20A Duplex (5-20R), 12V DC Automotive, Parallel
• Noise level: 53 dB (A)
• Warranty: 3-year limited

The Champion 3400 Watt Portable Inverter Generator is the ideal combination of flexibility and convenience. This contemporary dual fuel generator can run on gasoline or gas. Fuels can be easily changed by quickly turning the gas selector knob. Once the system uses gas, its 79cc motor generates 1,850 running watts and 2,500 watts initially. Using gasoline, the generator can run for 11.5 hours out of a full tank at 25% load capacity.

On the other hand, the motor of the engine provides 1665 running watts and 2,500 starting watts if you use it with propane. The Champions Inverter technology has an advanced economy mode. This can decrease the electric load. At the same time, it allows for quieter operation, offers reduced gas costs and extended engine life. This small RV generator is also equipped with cold start technology, which ensures immediate starting once the weather is cold.

This is just one of the best portable dual gas generators running at 53 dBA. So it doesn’t emit a lot of sounds. In addition, it includes a propane hose using a fixed regulator. The Champion generator comes with a 3-year limited warranty. Plus, it includes FREE lifetime technical support.

• Runs on gas and propane
• Portable design, easy to keep and use
• Ultralight construction
• Ultra-quiet operation
• The fuel tank is small

• Peak/rated watts: 2,000/1,600
• Engine:  79.7cc 4-stroke OHV
• Runtime: 6 hrs. (50% load)
• Outlets: (2) three-prong 120V, (1) 12V DC, (1) 5V USB port
• Noise level: 50 to 55 dB(A)

The Wen 56200i is a good balance between power and price. It is lightweight enough for ease of portability, quiet enough to avoid disturbing your neighbors while camping, and offers clean power for delicate electronics.

However, it is important to know your wattage and power demands for this one, because it would have trouble exceeding its described wattage and surge start-up wattage. But if you don’t have a lot of demands for this basic generator, it is a lot lower in price for many of the same features as the higher-priced competitors. It may not last as long as, say, the Honda, but it can keep up with your day-to-day needs, as long as they are not too strenuous.

Users have tested it on campgrounds, construction sites, during power outages and tailgates. Switching to the Eco-Mode may be necessary for it to power small appliances one at a time, such as microwaves or coffee makers.

The Wen may be very similar inside to the Yamaha, but it is missing a small door, which makes an oil change a bit more difficult: you have to remove the side of the generator. Having to oil it every 24 hours might be a bit of a pain, given this little flaw. The price tends to fluctuate throughout the course of the year, so make sure you get it when it’s cheapest, around $410.00.

• Light on fuel
• Reliable one-pull start
• Insides nearly identical to Yamaha
• Lower price
• Limited wattage output
• Oil every 25 hours
• No oil-fill door
• Our 1 pick for the: best carb compliant generators
• Our 1 pick for the: best 1000 watt generators
• Our 1 pick for the: best portable generator

Yamaha EF2200iS Inverter Generator

• Peak/rated watts: 2,200/1,800 (gasoline)
• Engine: 79 cc Yamaha MZ80 OHV 4-stroke
• Fuel tank: 1.24 gal.
• Runtime: 10.5 hrs (1/4 load)
• Outlets: (1) 120V 30A (TT-30R), (1) Duplex 120V 20A (5-20R), (1) 12V 3A
• Noise level: 57 dB(A)

Yamaha EF2200iS comes at around $700–$1000, which makes it also number one among the best generators under $1000 . The fuel gauge on the cap is a favorite for customers reviewing the product; the higher-priced Honda did not include one, to its detriment. There is a fuel shut-off valve with a carb clear out feature that allows the tank to dry out before you store it, to avoid problems starting later on. The carb drain gets out every last drop for even longer storage times – say, in the off season.

Additionally, the Eco-Mode allows for lower fuel use for a longer-lasting energy source. The fuel economy is one of the best, and this generator has the longest emission engine durability rating. The closable vent cap prevents fuel spills, and the generator weighs in at 55.2 pounds, making it easily portable to and from the dock.

This 2,000-watt generator can run for up to 10.5 hours straight without refueling at 25% load. It also comes with an easy-to-work recoil pull cord start.

• Fuel gauge on cap
• Fuel shut-off allows carb to run dry
• Easy first-pull start
• High fuel efficiency
• High emission durability rating
• Older models start to guzzle oil
• Expensive parts
• Our 2 pick for the: best yamaha generator
• Our 3 pick for the: best generator for tailgating
• Our 4 pick for the: best generator under 1000

Pulsar G2319N

• Peak/rated watts: 2,300/1,800
• Engine: 80cc single cylinder 4-stroke OHV
• Fuel tank: 1.18 gal.
• Outlets: (2) AC 120V 13A, (1) 12V DC 8A, (1) 5V DC USB
• Noise level: 59 dB(A)
• Warranty: 1-year limited

The Pulsar G2319N offers a power output of 1,800 running and 2,300 starting watts, and 6 hours of operation at half load on 1.18 gallons of gas, which is significantly higher than some (when measured) at only 25% load. At 47 pounds, it is lighter than all but the top two, Yamaha and Honda.

At 59 dB, it is reviewed as being quiet from at least 10 feet away, so it would follow that closer up, it is not quite as quiet, similar to the Briggs-Stratton (you need to be 7 feet away). Sine wave technology allows it to be safe for charging delicate electronic devices.

It has parallel capability, so it can be used alongside another one for more power. There is a 5-volt USB outlet and cigarette lighter – this works really well with the cable included when it is used to charge batteries. There were a few issues with the pull starter – they seem to be a bit fragile and are easy to snap.

But overall this device offers a great capability at a good price. A note of caution: the manual directions could be more clear. The battery switch must always be on before you try to pull-start or the auto-choke will flood the engine. Also, in order to manually shut down the generator, you must use the auto start/stop button.

• Parallel capability
• Low-oil shut off
• Shorter warrantee than most
• Pull-cord is delicate
• Louder than more expensive models
• Our 7 pick for the: best 2000 watt generator
• Our 10 pick for the: best quiet generator
• Our 8 pick for the: best inverter generator
• Things to Consider

In this buying guide we have answered some common questions which can lead you through the ins and outs, frequently-asked-questions and common misconceptions which will affect your considerations when purchasing a generator.

Taking your generator to a boat: What should you consider in the first place?

A generator must be lightweight and portable enough so you can easily take it to/from your boat. You should prepare your generator for a boat. You need to make sure that there are no exposed metal or metal parts inside the generator that might rust when exposed to humid conditions or salt spray.

It is fairly easy to take the screws out and remove the plastic outer cover of the generator in order to cover the screws and hardware in rust-preventing spray paint. Use something like Bowsheild T-9 to cover the electrical parts of the generator, and high heat paint for muffler if you are concerned about moderate heat build-up in tighter spaces on the boat.

• Do you need to ground a generator on a boat? Are there generators that don’t need to be grounded?

According to the National Electrical Code 250.34 Generators-Portable. “The frame of portable generator is not required to be grounded to the earth if the generator only supplies equipment or cord-and-plug-connected equipment through receptacles mounted on the generator, or both, and [the] metal parts of the generator and the grounding terminals of the receptacles are bonded to the generator frame.”

Under conditions that are the same as the NEC, OSHA directs (29 CFR 1926.404(f)(3)(i)) that “the frame of a portable generator need not be grounded (connected to earth) and that the frame may serve as the ground (in place of the earth).”

• What will you power on a boat?

If you want to power some simple things like hair dryer, electronics, and small devices like a coffee maker or microwave, or even a dishwasher on your boat, then a small portable inverter generator should be more than enough to meet your power needs, like for a example Wen model, which is also considered to be one of the best Wen generators .

However, if you must have air conditioning or appliances that suck up a lot of power in a short time, like a fridge/freezer, then you might as well consider going with a traditional, more permanent marine generator.

The generator you choose must have enough power capacity and the correct outlets for the specific devices you have, and the combined wattage to power them, concurrently if necessary. Many inverter generators have more than one mode, so they can be used to power a greater or lesser load at different times, without compromising the integrity of the output. Most also have eco-modes to reduce the RPMs to save gas while powering smaller loads.

• Conventional vs. Inverter Generator

An inverter, on the other hand, draws power from a fixed DC source (i.e.: battery) and inverts the power into usable (most likely 120V) AC current.

Inverter generators combine the best of both worlds through the use of advanced electronics. They combine the technologies of both traditional generators and traditional inverters to first generate AC current, which is converted to DC, then inverted back to AC power in a pure sine wave that will not fluctuate and cause problems for its users.

And please don’t forget the option of the portable power station , which will be also suitable and less noisy, especially for shorter trips.

• How long do you need a generator to operate?

You must calculate the amount of time which you need the generator to run and then compare this with the generators which are listed here. They have different runtimes and fuel capacities. In addition, certain fuels have better economy than others.

Propane powered generators don’t get as far on the same amount of fuel because unfortunately, propane has less potential energy in its raw form than either gasoline or diesel.

From Wikipedia, “propane is capable of producing 84,300 BTU’s per gallon, gasoline is capable of producing 114,000 BTU’s per gallon, and diesel is capable of producing 129,500 BTU’s per gallon. In layman’s terms, 26% more propane is needed to produce the same amount of energy as 1 gallon of gasoline.”

Accordingly, 35% more propane is needed to produce the same amount of energy as 1 gallon of diesel, as it is in case of the best diesel generator . A converted Honda EU2000i generator could use a 20–30-pound propane tank.

The generator specs given in this article can be used to determine average times that the given generators will run on a partial load. It follows that if the load is increased, the runtime will decrease accordingly.

If you need to run a lot of appliances on your generator for a longer time, it may be worth it to invest in one of the more expensive, longer-lasting generators such as the Honda or Yamaha . Or you could try the Champion , which is more budget-friendly.

• How noisy is a generator?

The design of a generator has more to do with noise level than the fuel used to power it. It is helpful to check the noise rating (and the fine print included there) to determine just how noisy or quiet a generator will be.

Some generators will be noisier because their rating was determined from 7 to 10 feet away, whereas the noise level of others was tested whilst standing right next to it. Most of the inverter generators that we have reviewed here were created to be less noisy (or around the same) as a normal conversation or the quiet hum of a coffee shop.

Check how far away from the generator it was tested to determine how close you can be to enjoy this lower noise level.

Keep in mind that small, portable inverter generators that are reviewed here are specifically designed to be quieter than the larger, traditional varieties. This can be a good thing if you are going to be in closer proximity with other people, or of higher levels of noise will bother you.

Safety considerations

Safety is important, especially when you’re on board. Let’s have a look at the safety features that are essential in a marine generator and a couple of things that can add to your protection while using a generator.

• Low oil shutoff

Look for a generator with this feature that will shut itself down in the event of a possible overheating situation that could wreck it.

• Emergency stop button

Some generators have this feature included already; with others, you may need to buy an emergency stop button kit and install it yourself.

A delicate sensor is placed on the outgoing power source which monitors the amount of power leaving it. If the power surges for any reason, the power source cuts itself off, possibly saving your life, or the life of someone you love.

• Fire extinguisher

It is common sense to have a fire extinguisher on your boat, but doubly so if you have a portable generator with an independent motor creating heat and exhaust. There is a lot of energy and electricity being contained within a small area, and sometimes the unexpected can happen.

• Carbon monoxide detectors

Make sure you have at least one, probably even two carbon monoxide detectors located in the cabin of your boat in case the generator’s fumes incidentally end up in your living space. Follow the manufacturer instructions, talk to friends and experts, and read the following guidelines on safely placing and installing a portable inverter generator on your marine vessel.

• Tips and tricks

Installation

• always follow the manufacturer’s instructions
• place the generator on a flat surface that is free of debris, non-combustible and non-conducting
• Ensure adequate ventilation around the generator
• Direct emissions away from inhabited areas

Maintenance

• Turn off unit before dismantling or servicing
• Cover and insulate electrical surfaces
• Drain all carb before storage
• Don’t smoke near the generator
• Inspect all parts regularly: on a quarterly, six-month and yearly schedule
• Use your generator on a regular basis
• Don’t allow unused fuel to sit inside the generator
• Keep a fire extinguisher nearby

• Do I need to ground a generator on a boat?

Grounding rules state that you do not have to ground your generator if it only powers things that are plugged in through “electrical receptacles,” and the metal parts of the generator are connected to the generator’s frame, which serves as a “ground,” in place of the earth.

• Where do I better place a portable generator on my boat?

More than one is better, in case one fails. Ventilation is a serious issue on boats, since wind can blow even well-vented, properly directed fumes back over the boat or into the windows. You could also put it on the bow pulpit, but you must make sure the hatches are closed in this case.

• Do I need to protect a generator from water when using on a boat?

You should also cover the electrical parts with some type of protective covering and never take the cover off or service it while it is either turned on, in contact with water or connected to a source of power. These are reasonable precautions to take if you wish to avoid getting an electric shock. In addition, you should protect the metal parts with rust-protective coating.

Always follow all the instructions on the manufacturer’s manual.

• Our verdict

Out of all the generators we reviewed, the first, second and thirds spots went to the Briggs & Stratton P2200, the Honda EU2200i and the Westinghouse iGen2500, respectively.

The Briggs & Stratton P2200 was the all-round winner, since it it is an affordable model and scored so high in the most categories, including: one of the longest running, ease of start, PowerSmart mode, dual capability, noise level and good warranty length.

The Honda EU2200i came in second place, having almost identical performance and features. The second placing was mostly because of a slightly smaller fuel tank capacity.

Third place was awarded to the Champion Power Equipment 200961 . This model seems to give a lot for a little, having the highest surge watt rating of all the of the competitors. It also has up to 10 hours of continuous runtime on one gallon of fuel.

Buyer’s Guide

Power Output

The first thing you need to do is find out what you are going to power on your boat trips? If you will power sensitive electronics and other small devices, then a small size generator with 1600 to 1800 rated power output is enough. But to power large appliances, you will need at least 2200 rated watts.

Moreover, if you are going to power both small and big items simultaneously, then make a list of all those things and write their watts to calculate the total required power. In this way, you will find a perfect unit for your boat.

To make this clear and understandable for you, we have given an example below.

For the above setup, 5300 watts are needed to start all the appliances together, and 3600 watts are needed to run all the appliances at one time. If you know how to do load management, you can run all these appliances on a 3600 watts generator. The trick here is to add load one by one to your generator. Once they release the extra wattage needed to start the appliances, you can add more load. Smaller generators are cheap to buy and easier to maintain. They also have a low running cost.

Type of Fuel

It is recommended not to use propane on a boat because liquid gas can be hazardous. But nothing is stopping you from buying a dual fuel generator for other uses. You can buy a dual fuel generator for your boat and use only gasoline while you are out in the water. Gas is a safer option for boats. Overall, a dual fuel generator gives you versatility when it comes to the fuel type. When you are using the same generator at home, office, or RV, you can use propane without any issues. Propane is cheaper than gas, burns cleaner, and gives a better runtime in smaller generators. Gas availability is also jeopardized during natural disasters and infrastructural problems.

Control Panel

You must look for a generator that offers maximum options on the control panel. When you are out on the boat, you want things simple and under control. A fully advanced model will have an odometer, meter readings, on/off buttons, a choke, and power outlets on the control panel.

Power Outlets 

The next thing to look at is power outlets. Make sure the generator you are selecting has your desired power outlets. There must be two 120V AC outlets and a DC outlet along with a USB port. Also, try to get a generator with GFCI-protected power outlets.

Tank Capacity and Runtime

As you are buying a portable generator for a boat, tank capacity and runtime are vital to consider. It would help if you went for long boat trips for units with big fuel tanks; otherwise, a 1-gallon tank is enough to go for a 6 to 7-hour trip.

But a big fuel tank like 2 gallons or more is not enough if your generator is not fuel-efficient. Make sure your unit has an eco-mode. However, runtime also depends on the load applied.

Noise Level

It is always recommended to go for portable inverter generators to use on a boat to produce less operational sound. Less than 65 dB (A) operational noise is quite bearable.

Parallel Capability

For boat trips, a parallel capable generator is a must so that you can generate more power when needed. Paralleling also allows you to run more appliances as you get twice the number of power outlets. Having two small generators is always an edge because they can be used for two different purposes or at different places.

Throttle Control

One of the biggest benefits of buying an inverter generator is that it comes with a throttle control system. Throttle control or eco mode is a feature that helps in adjusting the engine output according to the load applied to it. If your generator has less load on it, it will reduce the output and increase it when the load is high. Such features help increase fuel efficiency and reduce operational costs.

Portability

You will have to carry your generator to your boat every time you set sail. Hence, look for a generator that comes with high-quality wheels, an ergonomic carry handle, and push/pull bars. You will be using this generator for your home or other purposes when you are not on your boat. So, you must never ignore the portability features in your generator.

Safety Features

Low-oil alert with shutdown feature and overload protection are the two safety features that must be part of your generator. Other than these, if there is an emergency stop button, then it will be a plus.

Weight and Warranty

Make sure your portable generator is light in weight. Also, it must have an excellent gripping handle to carry it quickly to the boat. Other than weight, the warranty period also needs to be considered. At least your generator has a 2-year warranty period.

Environmental Conservation

When you are on a boat, don’t ignore the environment. Buying a generator without EPA and CARB (for California residents) isn’t legally and ethically right. Uncertified generators hurt the environment by producing toxic and harmful chemicals. Hence, you must look after such things as well.

The last thing to consider is price. When you look for advanced generators with all the latest features, you will have to pay more. Such generators are user-friendly and easier to maintain. On the contrary, basic models are cheaper but often have a higher operating cost.

How to prepare a portable generator for a boat?

Before you can use a portable generator for a boat, you need to make sure that it is fit for the boat. All the electrical connections, spark plugs, screws, and other hardware will need to be covered with water-resistant materials. You will need to hire a professional to prepare the generator for the boat. Don’t worry. It can be reversed, and you can use your generator for non-boat purposes. However, it is better to keep a separate generator for your boat. You can use waterproof spray or cowling to protect your generator. For more detail, please check out the video here .

What’s the best place to install the generator on a boat?

First of all, it is not a good idea to install the generator permanently on a boat. You must keep it in a dry locker when it is not in use. The aft deck is the most appropriate place to keep a generator when it is running. A swim platform is also a good place for running the generator. To keep your generator secure, use metal brackets and pads. Pads help in reducing the vibration and running sound. Avoid placing a running generator near the cabin, windows, and doors of the boat. The cabin can fill up with smoke pretty soon, and it can become a health hazard.

How to can I connect my generator to the boat?

Some boats come generator ready. Other needs to be wired to make them generator ready. If your boat is not generator ready, you must hire a professional electrician to this task for you.

Is it safe to use a dual fuel generator or run a propane generator while on a boat?

It is safe to buy or use a dual fuel generator on a boat, but it is not safe to run it on propane. In case of leakage, the liquid propane will fill up the bilge, and any spark may have devastating effects on your life.

Do I need to ground a generator to use on a boat?

No, there is no need to  ground your generator  to use it on a boat. Grounding is necessary when your generator is hooked up to the building wiring.

Suppose the appliances and electronics are plugged in through electrical outlets, and the generator’s metal parts are linked to the frame of the generator. In that case, you won’t need to ground your generator.

What safety measures should I take while using a boat generator?

• Never refuel your generator while you are on a boat.
• Avoid running your generator near doors and windows to prevent your cabin from filling up with carbon monoxide.
• Avoid starting your generator near the damp patches.
• Make sure there is no fuel leakage.
• Keep your generator high enough on the boat to protect it from waves.

What are the maintenance needs of a portable boat generator?

When you are running your portable generator on a boat, you need to be more careful and vigilant about its maintenance. Inspect your generator after every tour and ensure that its components are free from water. Make sure that waterproofing is all okay. Besides post-tour inspection, you must also do periodic maintenance for your generator like spark plug inspection, checking engine oil and oil/air filter, and battery recharging.

A boat trip with a generator on board is always a pleasant experience. When you have ample power for all your appliances, you enjoy your time out in the sea with your family and loved ones to the maximum. You can cook better, sleep better and enjoy more. All the generators reviewed above are of high-quality and will go a long way with you.

How to Prepare a Portable Generator for a Boat?

Portable generators have been a very important part of many homes and businesses, but they can also be used for boats.

This will allow you to use the power of your boat without having to rely on shore power or running out of fuel.

Let’s discuss how to prepare your portable boat generator. Follow these for safe operations and best fishing trips, follow these steps:

• Clean and inspect the generator.
• Connect the battery and connect the power cord.
• Make sure the oil level is correct.
• Add gasoline
• Plug-in electric starter
• Verify spark plug
• Turn on engine
• Add one or two tablespoons of oil to the engine.
• Check the oil level.
• Stop the engine
• Unplug electric starter
• Turn off the fuel valve
• Disconnect battery
• Move generator

1 – Clean and inspect the generator: The first thing that you need to do is clean and inspect your generator for any problems.

Ensure that the plug is clean and that no oil or gas is spilled anywhere.

2 – Connect the battery and connect the power cord: Once you have done this, connect the battery and plug in the power cord.

Make sure that the outlets are ready to use and that nothing is blocking them.

3 – Make sure the oil level is correct: After doing this, make sure that the generator has the right amount of oil in it.

You can do this by following the instructions in your manual.

4 – Add gasoline: Once you have completed these steps, add gasoline to the generator.

You may need to use a funnel if there is not an easy way for it to get into the generator.

5 – Plug-in electric starter: After filling up the tank with gas, plug in the electric starter to the generator.

6 – Pull rope: Pull the cord on top of your generator. Make sure that you do this slowly and wait a few seconds each time before pulling it out.

7 – Verify spark plug: Once you have done this, look for a small spark plug under the cover. If the engine starts, you should see a small blue spark under here.

8 – Turn on the engine: Once you have verified that this is working properly, turn on your generator and allow it to warm up for about five minutes.

9 – Add one or two tablespoons of oil to the engine.: After waiting for 5 minutes, add 1-2 tablespoons of oil to the generator.

Turn off the engine and wait for 30 seconds before restarting it.

You should see a small pool of oil in the bottom of your generator if you use one tablespoon, but if you choose to use two tablespoons, you might not notice this happen.

10 – Check oil level: Once this is done, turn off the generator and wait 30 seconds. Look at the oil level in your generator to make sure you have enough.

11 – Stop the engine: After doing this, turn off your engine completely.

12- Unplug the electric starter: Once you are done with this, unplug your electric cord from the back of the generator.

You can either do this by pulling it out or unplugging the cord itself.

13- Turn off the fuel valve: Now, make sure that your gas is turned off, and nothing is open at all except for the choke (if there is one).

If you have an electric generator, then just turn it off completely.

14- Disconnect battery: Once you have done this, disconnect your battery from the terminal.

15- Move the generator to where it will be used: After doing all of these steps, find a good spot for your generator and place it on a flat surface.

You can do this in a garage or outside if there is a good place to put it.

Ensure that nothing is blocking the generator and that it is not in the way of other objects.

Safety Measure while using a boat generator

The starting and running components of a gas-powered boat generator are the same as those found in any gasoline engine.

Refer to your owner’s manual for instructions on how to check and change the oil, and install spark plugs and hydraulic belts.

Then follow these safety tips:

• Make sure that no combustible materials — such as rags, gasoline, or paint thinner — are in the area.
• Always disconnect the shore power cord before starting the engine.
• Keep an approved fire extinguisher, Class B-rated gas can, and extra fuel on hand when fueling.
• Position your generator so that exhaust fumes vent away from living spaces. Note: On boats with enclosed cabins, it is often necessary to install an after-market venting system.
• If the generator’s installation requires running wires under the floor or through a wall, make sure that the wiring is installed correctly and in compliance with local electrical codes.
• Do not store gasoline containers on your boat while you are sleeping there.
• Never run a generator on board your boat while you are sleeping. Please note: Allowing the exhaust to vent into an enclosed cabin violates EPA emission standards and can be hazardous; some states prohibit this practice. If you choose to use a generator in such a way, make sure there is adequate ventilation or that the unit has an approved carbon monoxide monitor.
• Install a carbon monoxide monitor, and never use a generator in an enclosed area without adequate ventilation. In addition to using generators carefully on board your boat, be safe everywhere else: Never operate gasoline-powered equipment or tools near an open flame or while smoking.

Final Verdict

RV and boat owners, like most other people, want to be prepared at all times for any emergency.

With a generator onboard, you can enjoy the boat trip to your heart’s content.

You’ll be able to cook better and sleep better with an ample supply of power for all your appliances.

All of these generators offer peace of mind and also help save money since they don’t require refueling!

These best portable generators for boat use will be able to provide all the power you need for your family boat trips now and in years to come!

If you’re looking for a high-quality generator that will last through many trips out at sea, look no further than our review above.

FAQs: Best Portable Generators for Boat

What is the best place to install the portable generator on a boat.

The best place to install a generator in the boat is in the engine compartment because it’s protected from rain and spray.

Installing a permanent generator on your boat can be dangerous and unhealthy.

You should keep it in dry locking when not running, but you may want to install one if there’s no other place for storage or protection from weather conditions like spray!

Make sure that the location will avoid filling up with smoke – stay away from decks near cabins where people spend the most time during their day (especially kids), and windowsills inside living spaces open into exterior areas accessible at sea, like swim platforms.

These locations could become hazardous quite quickly, so make certain first before committing yourself by installing them permanently.

Do I need to ground a generator on a boat?

The short answer is no, but with some caveats. A properly designed marine generator should have its own isolated neutral so it can be used close to the metal without creating any safety issues.

That being said, grounding the generator won’t hurt anything; you just don’t have to do it.

Charging Boat Batteries With a Portable Generator

Published on April 26, 2023 ; last updated on April 25, 2023 by Carolyn Shearlock

Charging boat batteries with your portable generator? Can you do it? Should you do it?

Many cruising boats carry a small generator aboard, most often a Honda 2200 (Amazon) or its predecessor, the Honda 2000. The Hondas are quiet and long-lasting. Plus you can find parts and service shops easily. The biggest problem with them is that they are pricy. A few copycat brands are starting to emerge. And some cruising friends are reporting good results although they admit that it’s too soon to really know the longevity. 

These are not the same as built-in generators. They generally produce more power but are also larger. They are truly built for marine conditions, which the small generators are not. However, many boats do use the small generators – us included. 

Choosing a Portable Generator

If you start looking at portable generators, you’ll see that there are many with more power for less money than the Honda 2200 (or the copycats). The big differences are the noise level and size. You do not want what’s called a construction generator – the noise is just obnoxious. And it will drive you and everyone else in the anchorage nuts. The Honda 2200 is the quietest I know of.

We previously had a Honda 2000 and switched to the 2200 when we inherited one from a friend who died last spring. The 2200 is noticeably quieter than the 2000! 

These generators weigh about 40 pounds. And you can use them to charge batteries or run a watermaker or power tools. (You can also run power tools off your house batteries with an inverter.)

Charging Boat Batteries – How To

The Honda 2200 and most copycats come with a 12V plug and I often get asked if that’s the best way to charge boat batteries. No, it’s not. That outlet only puts out 8.3 amps – it will take all day to charge your batteries! 

Instead, connect the generator’s 110v outlet (what looks like a standard household outlet) to your boat’s shorepower cord and use your shorepower charger to charge the batteries. This way, you’ll be able to charge much faster – most likely you’ll put in about 80-90% of the amperage your shore power charger is rated for. 

Most likely, your shorepower cord will need an adapter to connect to the generator. Boats generally have either a 30 amp or 50 amp shorepower cord (and those with a 50 amp usually have a built-in generator), while the generator has a 15-amp outlet. You need a 15 amp male to 30 (or 50) amp female adapter, such as this one (Amazon). Because we use our generator to also run our watermaker, we always carry a spare adapter just in case we drop one overboard (we never have but there is always that risk). 

Charging Speed – What to Expect

Readers often ask why the generator isn’t charging the batteries as quickly as they expect. The speed of charging is governed by the lesser of the generator’s output or the size of the shorepower charger and by how full the batteries already are.  

The generator size usually isn’t the limiting factor. The first culprit is an undersized shorepower charger. If you have, for example, a 30- or 40-amp charger, that’s the most the generator will be able to put into your batteries. Actually, due to inherent losses in the system, you’ll get somewhat less.  

You’ll put in far more with a larger charger. We have a 120-amp charger and typically put in about 75 amps, so charging takes much less time and uses less gas. 

Additionally, how much charge your batteries will accept is governed by how full they already are, particularly with lead-acid or AGM batteries. The closer they are to being fully charged, the less charge they’ll accept. So, if you also have solar power – assuming that the solar panels put out less than the wattage of the generator, which is virtually always the case – it’s best to run the generator for a limited time early in the day when your batteries are at their lowest and then let the solar panels finish the job.  

Portable Generator Safety

Finally, you have to carefully consider the safety aspects of using a small generator on a boat. Carbon monoxide poisoning is a real risk if the exhaust gets funneled back into the boat. You absolutely must make sure that the exhaust is directed away from the boat’s interior. I recommend having a CO alarm. Additionally, it shouldn’t be left uncovered or run in the rain. And you’ll have to carry more gasoline to power it. 

We live primarily on solar power. However, in winter and periods of prolonged cloudiness, it’s just not quite enough and we really don’t have room to add more. Running our diesel engine just to charge the batteries is hard on it (diesels like to be run with a heavier load on them than is required for just battery charging). So charging boat batteries with a small fuel-efficient generator just makes sense.

So very true about the use of the Honda Generator. I live and swear by it. I run small book shelves heaters in the winter along with the used of charging my AGM batteries. It is a must needed tool for any boat.

Nice info. we use a dual fuel generator from Champion, so far have only run it on propane, much cleaner but not as energy dense as gasoline, only 1800 watts instead of 2000. For me, the tradeoff is worth it as I don’t have anything that runs on gasoline aboard, but I use propane already in the galley. You can find conversion kits online for the Honda but they’re a little pricey, like a Honda. What’s nice about propane is that it doesn’t go bad, your carb. stays clean and a 20 lb. canister will run the generator for 24 hrs~ continuously. Cheers, Cabot

Hello Cabot- I also have a Champion Dual Fuel 2000 W generator. I connected mine using a 30 amp to 15 amp adaptor to the shorepower cord through the 120V plug on the generator. I also used only propane to keep gasoline out of my lazarette. The generator, however, kept tripping its overload breaker. Have you experienced any similar issues? Dave

I have a 92 30T Hunter and was planning to get away for a week or so sailing in Oklahoma. I want to tie up or anchor in some off beat areas. We currently have heat advisories in the forecast, the boat has an onboard cooling system (water cycle type) that came as an option on the boat along with the refrigerator. I use these items at dockside but not out at anchor. My questions is can I purchase a nice quiet portable generator like a Honda 2000 and plug in my shoe power cord to it an safely power the boat? I'm not very familiar with the voltage /amps needed to do this and the output of such a device. Thinking it couple be a nice source of power to enjoy more days away from the dock in high 90 and 100 degree weather. Thoughts and ideas and experience appreciated.  

I have the Honda 2000 and use it on anchor, but not for heat/AC.  

Yes you can, you can purchase an adapter commonly known as a pigtail to connect your shore power inlet port to one of the 15/20A output receptacles of a Honda 2000. There is Honda model that comes with a 30A receptacle and can accept you shorepower cable. By the way Honda 2000 is the standard as far as portable generators go, it is quiet and very reliable. The thing you need to know is that the output of the Honda 2000 is limited to 16A which is about 1/2 of what your 30A shorepower connection is . Most electrical appliances will have a tab indicating their load rating. So by simple sum you do not want to run simultaneously appliances and fixtures that will draw more power than 16A. There is one caveat and that is that appliances which have electric motors like compressors and fans will require up to 3 times their load rating at start up time. An appliance that cycles on and off like an A/C or a refrigerator will require that surge of power every time it cycles on. Honda's have a safety switch to protect the generator in case of an overload; it will just shut off power. The generator can basically run an A/C unit of 8,000 BTU or it can run simultaneously a refrigerator, an inboard battery charger and cabin lights. Some have added a Soft Start capacitor to their larger A/C units with different degrees of success. The fuel tank is close to 1 gallon and in the economy mode it can run some 6 hours. If the load requirements are large the ECO mode must be turned off and expect a noise increase as well as shorter run time of around 3 hours. Not familiar with your water cooling system, is that like a swamp cooler? They do not work very well in high ambient humidity.

Then there is the need to deal with the exhaust. We were using a Honda generator out in the cockpit directing the exhaust off the boat. It was icy cold. The generator was providing support to the heater keeping the cabin above freezing. About 02:00am the wind changed started blowing the exhaust onto the boat. About 02:10AM one of the carbon monoxide alarms goes off waking the boat up. Then a second chirps in. We bail out of bunks turn off the generator. Open the windows. Air out and cool down the boat while bundled in blankets. The CO alarms eventually stop. The former fireman in our group stays bundled in his sleeping bag snoring. The boat owner and I agree to wake each other in an hour to see if we are alive. Not much sleep the rest of the night. Be sure you have good working CO alarms on board if you plan to operate a generator.  

JSSailem is correct about being extra careful with the exhaust. I use mine on deck tied to the hand rail and a stanchion base and as the boat swings and points to the wind the exhaust usually exhaust to stern. Even in the case of currents turning the boat away from the wind the exhaust seems to flow over the cabin. Have had a couple of CO alarm scares but I largely supect they were false alarms. Jump up, better safe than sorry.

I have a honda 2000EU with the twist lock comnector. It runs my 16K BTU dometic turbo without a problem. If I also try to hook up my charger/invertor I run into problems unless I lower the charger output. I use it off the back of the transom and I use CO detectors too but I have never run it overnight. It's "probably" safe, but I sleep better knowing I will wake up.  

Then there's the noise. In a crowded anchorage it can be a bit obnoxious to run one on your deck or at your stern for extended periods, let alone all night for A/C. I would be really hesitant to run a gas generator on a boat. Gase engines generate much more CO than diesel. And, a properly installed, albeit much more expensive, marine diesel generator is much quieter and much safer than a portable gas genny.

Not sure but Jim Seamans who used to own a hunter 356 used a Honda 2000 to run his AC onboard. Name of his boat was called JAVA. SEE IF HE MENTIONED ANYTHING ON THAT IN THE ARCHIVES  

jssailem said: It would seem that the quietness of a diesel generator is a subjective observation. Granted it can be located inside the boat but still the relative dBA claims are very close when the diesel generator is equipped with sound suppression.

[SIZE=4][FONT=arial]Benny17441[/FONT][/SIZE] , that's really great, insightful advice about being "extra careful" about the exhaust. After alI, my advice as only a lay person would have been just to be "careful" with the exhaust, but I don't have a degree in Naval Architecture and Marine Engineering. Please let all of us lay people know where your degree in Naval Architecture and Marine Engineering is from, so we can all know how you can come up with such brilliant scientific and up to date recommendations. I also bet your on the council of ABYC as your genius should be an inspiration to us all. Please do not hesitate to continue to shower all of us with your truly inspiring knowledge.

tfox2069 said: Fair question, but my guess is they'd not recommend it. Regardless, I know a LOT of boaters have accepted these risks in order to get the benefit from the generator (I'm one of them). Click to expand

Advice freely given about portable gasoline generators on boats is going to get people killed . tfox2069 , you know and accept the risk. You have done the research with the manufacturer and have received clear instructions NOT to use the generator on a boat. I take exception to self proclaimed "experts" like Benny17441 giving out advice that is totally wrong . An unknowing and foolish individual taking this "expert" advice is putting lives in jeopardy, and may not be aware of the risk. Personally, I don't understand why Honda and other manufacturers don't put an orange warning label on their generators clearly stating, "NOT FOR USE ON BOATS" . My Hunter has such a label warning of CO in the swim platform, why don't generators have the same? When a death occurs, and it surely will, the trial lawyer will have a field day as what would the defense be? Everyone knows not to use these generators on boats, but everyone knows that's exactly how their being used.
