Positive Latitude at Anchor

Maintenance Log and Captain’s Log Templates

We’ve been using a couple of spreadsheet templates on m/v Positive Latitude for a while now to capture important information we want to track about our cruises (Captain’s Log) and all the maintenance we perform on the boat (Maintenance Log). There are a lot of good applications that accomplish the same thing but we want to customize and we don’t want to start over when an application we like is no longer supported. If you are interested in receiving the templates for free, fill out the form below and we’ll send you a link. An understanding of spreadsheets is useful or at least the desire to jump in and figure it out. Feel free to modify for your own use. If you don't use Excel, the templates seem to work fine in Google Sheets and Libre Calc.

Maintenance Log

Captain’s Log

The workbook contains worksheets for: Deck Log - includes calculations for entry Daily Time Underway as well as a summary of Total Hours Underway, Total Days Underway, and Total Miles Marina and Anchorage Log - includes calculations for each entry for Total Cost, and a summary breakdown by # of Stays, # of Days, and Total Cost by type (Marina, Mooring, Anchorage, Yacht Club, and Free Dock) Fuel Log - includes calculations for entry Price per Gallon, Hours Since Last Fill, and Gallons Per Hour as well as overall Average Gallons per Hour. Pumpout Log - includes calculations on each entry for Days Since Last Pumpout as well as Total Cost.

The grey boxes on the worksheets are calculated fields so you shouldn't enter any info in them directly - those get updated automatically as you enter new information. We start a new log file each year and store our log files in the cloud (One Drive is what we use, but there are many options). We can update using a laptop, a tablet, or even our phones, and the files get synced across our devices. However, you can just keep the file locally on your computer if you'd prefer.

Reasons to Keep a Boat Maintenance Log

  • By Rich Johnson
  • Updated: August 10, 2021

Collection of boat maintenance notebooks

Death and taxes—the only things you can really count on, or so they say. Of course, if you own a boat, there will be the eventual sale of that boat, which is kind of like death.

Hey, cheer up. Maybe the sale of your boat is so you can buy a different one—bigger, faster, prettier and better equipped. Regardless, it is true that at some point all of us will face the prospect of selling a boat.

No matter how you feel about selling your boat, the process will go easier if you have kept a detailed maintenance log extending all the way back to when you bought it. The reason this will ease the process is because the prospective buyer will feel much happier and more confident about the condition of your boat if he or she can see that diligent attention has been paid to maintenance.

Maintaining an outboard motor

Along that same line, when you buy a used boat, you will want to be able to check over the maintenance log to make sure everything has been done to keep the vessel in satisfactory working order. So, a good maintenance log is a big deal, whether you’re selling or buying a boat.

As an owner, a maintenance log is a great aid in caring for your boat. Noting the dates of regularly scheduled maintenance items, such as filter changes, and oil and other fluid changes, makes it easier to care for your boat, its engines and its systems. Additionally, unscheduled maintenance, such as battery swaps, sacrificial-anode replacements, steering-cable replacement, topping off hydraulic fluid, etc., will help you and prove more valuable with time. That’s because the longer you keep a log, the more patterns of wear—based on your individual use—will begin to appear. So, you’ll know to replace the battery or cable before either leaves you stranded. Track your fuel purchases and engine hours too because fuel quantity burned versus hours is a good barometer of engine health.

Changing fluids on an outboard

It’s also helpful to keep track of part numbers, like spark plugs, filters, O-rings, the ignition-key number, etc. Also note fuse and breaker types, and the amperage ratings for all your devices. Note the bulb type and amperage for all lights. Doing so makes it easy to buy replacements. Reserve two or three pages at the back of your notebook as a repository for this info. If your book has pockets on the covers, you can rip off the labels of parts boxes and keep them handy for reference.

But for now, let’s talk about you as a seller. Remember, a log is not only about maintenance. It should include the date when any new equipment was added. It’s a good idea to make note of the cost of parts and labor, which will help justify the price you ask for your fine vessel. And be sure to save all the owner’s manuals and receipts in a secure and well-organized place so you can pass them along to the new owner. In essence, any time you do anything to the boat, whether it be service-related, routine maintenance, parts replacement, or adding new goodies, write it down in the in the logbook. That log will be money in the bank when it comes time to sell. Here’s how to make a good one.

Notebook with data in it

Jot These Things Down

Get Organized

A maintenance log, in my opinion, should be nothing more than lined pages on which you can make notes about everything that is done to the boat. If the log is already organized into categories for things such as engine- oil changes, filter changes, etc., it will be less inviting and more cumbersome to make notes about all the noncategorized things. There’s a ton of stuff to be written in a maintenance log, so don’t constrain yourself by having a logbook that boxes you into a limited number of categories.

Neatness Counts

Take the time to write clearly so future owners can easily read what has been written. Include part numbers and brand names. Note sources where you made purchases so future purchasers might be able to go to those same sources for parts and supplies. For some things, make note of not only the date but also the engine hours when the service was performed. If someone else did the repair or service, make note of who did it, their address and phone number.

Make a List

Make note of all boat work in your maintenance log, no matter how trivial it might seem to you, and include the date of the work and engine hours at that particular time. Your list will be extensive, but key service elements to document include new fluids, filters, belts, hoses, tanks, fuel lines, batteries, cables and pumps.

In addition, don’t forget to log the addition, replacement or service of equipment such as deck hardware, smoke and CO detectors, marine electronics, canvas, the marine sanitation system, lighting, throttle and shift cables, hydraulic systems, bottom paint and more.

Depending on your boat, there might be more categories on your list. But do yourself a favor and fill out the maintenance log as thoroughly as possible. This might seem tedious, but it’ll pay off in the end.

The Ultimate Sailboat Maintenance Checklist...

The ultimate sailboat maintenance checklist.

sailboat maintenance

Pop quiz: when are you finished with maintenance on your sailboat? It’s a trick question. The real answer is “never,” because a sailboat needs regular care and attention if it’s going to perform at its best. And that care and attention won’t help if it isn’t comprehensive. That’s why we’ve put together this ultimate sailboat maintenance checklist to help keep your ship in top condition:

  • Inspect the boat. Survey the bilge, for example. Test the bilge pump and make sure it runs smoothly. Visually inspect the hull. Look for leaks. Check the raw water sea strainers and look at your battery levels on a regular basis. The key word here is “comprehensive.” Remember, without a comprehensive inspection, you won’t know which issues need addressing.
  • Inspect your anchorage. Keeping an anchor in proper condition is essential. You don’t want to head out on a journey and find out that your anchor is suddenly flawed. Some experts recommend waiting for clear waters and weather and diving down to check the anchor itself.
  • When in doubt, get a second opinion. If you’re not sure about the quality of a particular system, you should bring in an extra pair of eyes—preferably an expert’s pair of eyes. It’s better to know that your sailboat doesn’t have a problem than to wonder.
  • Write down your regular maintenance habits. Add a date next to your notes so you know what needs to be done first. You’d be amazed at how much time can pass since you inspect a critical system if you don’t track it. By tracking it, you’ll know which spots on your sailboat deserve the most attention next time around.
  • Look at the quality of your sailboat’s wood. A sailboat’s wood is comparable to its lifeblood. You don’t want dry rot to set in and completely change its quality. We recommend a range of Wood Restorers that can help you out here if a total replacement is not needed. Our Git-Rot Kit is particularly helpful. It uses capillary action to penetrate through wood rot and strengthen the wood to make it both sandable and paintable.
  • Keep it clean! If there’s one thing inexperienced boat owners often forget, it’s that keeping a clean boat can work wonders. Keeping your sailboat clean will help prevent mildew from developing, which in turn ensures that you don’t end up with a lot of strange odors that become hard to eradicate. We have a full range of Boat Cleaning Products here at BoatLIFE for you to peruse.
  • Address maintenance issues as soon as they arise. Don’t put a new issue, such as a strange noise, on the back-burner. You don’t want to find out about a new problem when you’re out on the water. You want to know everything there is to know when you’re safe at home.

Vessel maintenance log - what it is & how to manage it.

Vessel Maintenance Log - What it is & How to Manage it

To avoid unexpected surprises related to your vessel, it’s no secret that maintenance should be one of your top priorities. However, maintenance is includes a lot more than your regular checks, visual inspections and hasty examinations. 

Depending on the size and built of your yacht, there’s a significant number of tasks that need to be performed regularly to ensure its safety and performance. 

While maintenance mainly falls upon the engineer of the vessel, their ability to perform their tasks effectively affects the whole crew. This is why keeping a vessel maintenance log is crucial if you want your routine to be efficient and precise. 

In this article, we talk about the importance of a vessel maintenance log and give you a brief overview of its contents. To this end, we provide the main benefits of a vessel maintenance log and the main sections it should encompass. Finally, we look at some essential tools you can use to help you manage these tasks smoothly.  UPDATE 13/10/2021: Check out the new boat maintenance log feature of Plan M8

What is a maintenance log book?

A vessel maintenance log book is a rather simple, albeit very useful document. It contains a list of all the actions that need to be taken in order to keep your boat in perfect condition. 

vessel maintenance log

The booklet offers a detailed overview of all of the equipment that needs to be maintained and help you track maintenance history. Additionally, it can include precise information on things like: 

  • materials and time needed for maintenance
  • spare parts and suppliers
  • the operator in charge of the maintenance of a particular piece of equipment 

Note that every vessel will usually come with its own maintenance log and the concept is important yet somewhat outdated. Let’s briefly go through the importance of a maintenance log before looking into more efficient, alternative solutions.

Why is keeping a boat maintenance log important?

Beyond the obvious benefits of staying organized and up to date with your maintenance, there are some additional advantages of keeping a precise vessel maintenance log. 

Save on upfront costs

Keeping a detailed vessel maintenance log will allow you to know exactly when to repair or replace old equipment. You will gather data regarding failure patterns, expenditure, and repairs. This will allow you to save up a lot of money in the long run. 

For instance, let’s say you have a piece of equipment that fails regularly. The maintenance vessel log will show you the pattern of breakdowns that needs your attention. It should allow you to opt for a new piece of equipment that will be more efficient and cost-friendly. Not to mention, the added warranty that would minimize maintenance costs even further. 

On the other hand, the absence of a log can also lead to a disorganised maintenance schedule and more breakdowns. In turn, your ship will be stuck in port, keeping your crew idle and wasting money instead of earning. 

Finally, the repairs themselves can be quite costly. Add up the overtime for repair technicians and urgent parts deliveries and it becomes clear how keeping a vessel maintenance log becomes a money-saver. 

Identify trend across equipment parts, brands, and components

Keeping a vessel maintenance log will help you clarify recurring trends related to equipment. You will be able to draw patterns across models, brands, and components. 

This, in turn, allows you to highlight the best course of action when it comes to durability, repairs, availability, etc. 

Adding to that, the more consistent your maintenance log records are, the more pertinent the data will be. This data will then be crucial for you to avoid any money-sinks, and to develop sustainable best-case scenarios for the equipment on board.  

Increase the safety of crew members

As we mentioned previously, keeping a detailed vessel maintenance log should result in fewer breakdowns. If your equipment is always kept in perfect working condition, it reduces the risks of accidents considerably. 

The log allows you to track your equipment’s health, ensuring a safer working environment for the most important resource - your crew. 

  • Prevent problems regarding warranty claims

Yet another benefit of carefully documenting maintenance and repairs on your vessel equipment, is that warranty claim processes become much more streamlined. 

First, you can track all warranty information through a single document. Easily accessing this information is crucial to be able to think ahead. 

sailboat maintenance log

For instance, it can be extremely troublesome when you are counting on a warranty claim for an essential piece of equipment, only to discover that its warranty has expired. Worse, this usually happens once the part has broken down, causing unexpected costs. 

Moreover, keeping the exact dates and types of maintenance done on your equipment will help you easily determine your rights on warranty claims.  

Track the crew’s accountability of certain pieces of equipment

Keeping a log of maintenance checks will allow for better accountability of the crew members that maintain and operate with the equipment on board. 

Crew carelessness can be a major factor in equipment failure. Thankfully, the vessel maintenance log can help you detect these patterns. You can then monitor crew-members that show signs of negligence and act accordingly. 

sailboat maintenance log

Furthermore, ensuring everyone knows that you keep these types of records will encourage the crew to be more careful with the equipment. 

And finally, the operators that are in charge of maintaining the equipment are equally held accountable for their work. This should ensure that the maintenance is always done up to the standards set up by the captain . 

Increase the resale value of your equipment (and vessel)

Record-keeping helps you prove that the equipment has been properly taken care of during the time it was used on the vessel. 

This can have a great impact on the decision of a second-hand buyer. The records paint a clear picture of the attention the previous owner has given to a certain asset. It boosts the buyer’s confidence that the equipment is in perfect condition and that it will serve them well. 

As such, equipment with maintenance records retains a much higher value than equipment with no vessel maintenance log. 

Create specialized maintenance programs

The equipment on your yacht undergoes widely different various working conditions and types of usages. Your vessel maintenance log will allow you to separate your maintenance programs into routine checkups and more detailed ones. 

Thanks to the log, you can cross-reference data such as part suppliers, repairmen, and technicians. You can then create specific maintenance programs for each type of equipment. 

For instance, it can help you set up routine lifeboat equipment list checkups on shorter intervals and in-depth engine and hull checks for your lifeboats on a 6-month basis. 

Main elements of a yacht maintenance log

Generally speaking, vessel maintenance logs have two main sections, that can contain different types of information: 

General equipment information

This section contains the information needed to identify the piece of equipment that needs your attention. This includes: 

  • The name of the equipment. 
  • Type of equipment. 
  • Model and manufacturer. 
  • Serial number. 
  • Location on the vessel. 
  • Crew members responsible for the equipment. 

In addition to this basic information, you can add some additional pertinent data such as: 

  • Date of purchase. 
  • Purchase price. 
  • Warranty duration and/or expiry date. 
  • Spare parts in stock. 

Maintenance calendar

The second, and equally important section of your vessel maintenance log will be your maintenance calendar. In this part, you will record crucial data such as: 

  • The description of the maintenance. 
  • The scheduled maintenance date.  
  • Crew-members involved in the maintenance. 
  • Eventual external technicians, service providers, and/or part suppliers.

Boat maintenance checklist 

Providing you with a complete checklist of all the tasks that need to be carried out on a vessel could be a bit of an overreach. However, this short checklist should give you a good idea of what to expect when planning your boat maintenance. 

  • Engine - check for corrosion, cracked hoses, leaks, etc. 
  • Propeller - critical for performance and fuel economy, the propeller will need a thorough check before every launch. 
  • Battery - must be checked frequently as it can be subject to corrosion. 
  • Electrical lines - deteriorating electricals can be a fire hazard. Check out this article for additional information on yachts’ electrical systems . 
  • Oil - staying on schedule with oil checks is a determining factor in avoiding critical engine failures. 
  • Other fluids - steering fluids, coolants need to be checked periodically to ensure smooth sailing. 
  • Hull - check frequently for cracks and blisters and avoid costly leaks. 

Check out the video below for a visual representation of a boat maintenance checkup. 

As you may be able to tell, maintenance is as important as it is chaotic. Organizing task history into regular notebooks and excel sheets can quickly lead to an overwhelming amount of data that can confuse both the captain and the engineer. 

Aside from that, you will often have to make smaller notes and highlights about your tasks, which makes record-keeping even more complex.

Thankfully, there is a solution!

PlanM8 - boat maintenance log book software

  • Saving you time and money.
  • Identifying maintenance trends.
  • Increasing safety.
  • Streamlining warranty claims.
  • Tracking the crew’s accountability.
  • Increasing equipment resale value.

  • The mast cap is out of sight, out of mind 99% of the time, but serves multiple functions: backstay, forestay, cap shrouds, radio antenna, nav lights, halyard sheaves. Rotate mast and boom sheaves to check they are not misaligned or worn by a bad halyard lead. Lubricate sheaves with WD40 or silicone grease.
  • Spreaders, gooseneck, mast heel, kicker, mainsheet and topping lift connections all need checking for wear, damage or corrosion.
  • Check for galvanic corrosion between different metals.
  • Check electrical connections, deck and spreader lights.
  • Wax mast tracks and luff grooves with candle wax or Teflon spray.
  • Standing rigging: Look for areas of wear or stranding on the wire. Check mast tangs, T-ball joints and rigging screws.
  • Wash furling drum and swivel and check they move freely. It’s common for the top swivels to become stiff and sometimes seize, which can compromise the forestay wire.
  • Running rigging: check for chafe and that the shackles aren’t seized. Sheets, halyards, warps: wash in fresh water to get rid of salt and grime.
  • Deck winches : strip down, wash parts in paraffin, wash off with soapy water and lightly regrease .
  • Windlass : if manual, check it’s working, clean and tighten. For powered versions check foot switch for water, clean and use Vaseline on the connections.
  • Anchor chain : Re-mark lengths if faded, or add chain markers. Check for condition and wear.

Head, bilge & gas

Check the bilge pump as part of boat maintenance

Check bilge pumps it might sound ok but is it actually attached to a hose?

  • Check impeller on bilge pumps and grease with water pump grease only (Vaseline will rot impellers)
  • If you have an automatic bilge pump, check float switches work.
  • Dry bilges thoroughly then if water appears after relaunch you’ll know you’ve got a leak.
  • Fill water tank and add purifier such as Puriclean or Milton
  • If the pump on the heads is stiff look to service and lubricate with silicon grease.
  • If you have a gas sensor, check it works.

  • Most vessels have DZR (dezincification-resistant brass) seacocks. Look for any signs of corrosion on the skin and tail joints, which are common points of failure.
  • Ensure all valves are greased.
  • All hoses should be double-clipped. Check jubilee clips for rust . Do you have wooden plugs attached in case of emergency?
  • Check skin fittings are free of blockages/ growth or antifouling.
  • Check anodes have plenty of life . Don’t forget prop shaft and saildrive anodes.
  • Check leading, trailing and lower sections for damage or hairline cracks.
  • Check for play in bearings, stock or quadrant. Movement should be minimal. Grease steering cable.
  • Check for stress cracks or movement internally and externally – especially at the keel root and around the internal framing or matrix, and around fastenings and backing washers.

Prop shaft & stern gland

  • To check bearings, grasp prop in both hands and try moving it up and down and from side to side. There should be little, if any, movement – no more than 2mm.
  • Check P-bracket for stress cracking from misalignment or damage.
  • Stern gland packing. Many yachts have some form of deep-seal arrangement that has a service life of around seven years. Those that have a proper stuffing gland will need to be greased to prevent drying out and getting brittle. The gland may need pulling down or repacking at some point.
  • If you have a saildrive, check the condition of the seal and the metal ring that holds it in position. Again, note the seals have a life expectancy of between five and seven years depending on manufacture.

Boat maintenance: Mechanics


Check all filters

  • If you didn’t change the oil when you laid up, change it now.
  • Change fuel filters.
  • Remove rags stuffed in outlet pipes from winterisation.
  • Impellers – if removed at lay-up – reinstall with a smear of water pump grease.
  • Reinstall the engine belts and check tension: there should be no more than half an inch of play.
  • Check oil levels. Check durability of the gaiter seal. Check rubber faring and reseal if necessary.
  • Change internal engine anode.
  • Check engine mount is secure.
  • Check diesel tank for water from condensation . Drain off or replace fuel. Add an appropriate biocide to help kill off diesel bug .
  • Check inaccessible wiring, such as bonding wires from the anode and earthing wires from the starter motor. Clean the terminals and smear them with Vaseline or silicone gel.

Batteries and electrical systems

  • Check electrolyte level if yours is an open lead acid battery; tighten battery securing straps and make sure vent for gases is clear. Clean terminals and coat with Vaseline. For sealed batteries, check the condition of indicator light, or other charge indicator.
  • Switch on instruments and use backlighting to help reduce any condensation.
  • If the anode looks serviceable for another season, check bonding and wires. If they haven’t worn at all they may not be working so check Ohm resistance max 0.2 from propeller to anode.
  • Check for chafe, wayward stitching and tears. Do you carry a sail repair kit?
  • Take to a sailmaker if the sacrificial strips is worn out.

Make sure your navigation apps are up to date

  • Update charts from Notice to Mariners .
  • For electronic charts, check with your supplier how to update. New chartplotters can connect to WiFi, or you may need to connect the chart chip to your PC at home and download the update.
  • Download operating software updates for your chartplotter and instruments.
  • Make sure your subscriptions for navigation apps on phone and tablets are up to date with the latest charts.
  • Check age of hoses. If they are over five years old, they should be replaced. Check for kinking or wear in gas hosepipes. If in doubt, replace.
  • Check hose clips are tight. Hoses behind cookers should be armoured.
  • Check thermal cut outs on hob, grill and oven work.


  • Check stitching and get repairs done by a sailmaker if necessary.
  • Jackstay and Danbuoy lines: check condition and points of security.
  • If you have the traditional type, check the bulb, battery and that it actually works. The new types have various ways of testing, and all have an expiry date.

  • Inflate using mouth tube. Leave inflated overnight to check for leaks .
  • Wash with fresh water
  • Weigh cylinder and check lights if fitted.


  • Check stanchions and make sure lifelines are still suitably secured at each end and cords and pins are in good order.
  • Watch out for wire failing if you have plastic sheathing.
  • Make sure these are in date, in a watertight container and are easy to reach. It’s worth having gloves and goggles to hand too.
  • Make sure these are in date and registered with the correct contact details.
  • Ensure this and the hydrostastic release are within the service date, and you are aware of its contents .
  • If its secured with a rope, consider if you could release it in an emergency with ease.
  • Make a grab bag up with essentials

How to Put Together an Effective Log Book

April 10, 2015 9 Comments

You are required to keep a Ship’s Log at sea, but there are lots of ideas about what exactly is required or useful in a log book. Finding a flexible, affordable, weather resistant solution is also not easy. We’ve found some solutions that you might find helpful.

The first boat we bought had a huge leather-bound log that they had religiously kept from the day she was launched forty years earlier. It had a screw-post binder which allowed it to grow over time by adding more pages. The one trouble with that log book was that experiential anecdotes were mixed in with maintenance notes and voyaging notes – it was very difficult to find specific references. The leather also had gotten damp over the years and looked a bit worse – more charismatic – for wear.

So for Phoenix we created two screw post log books, one for maintenance and experiential anecdotes with an index on each page, and a second Ship’s log for voyaging notes. Both are screw post books and both are filled with pages that can be printed on any printer.

Ship’s Log Book

Page from Ship's Log Book

Journal / Daily Log Book

Top of log book page

The Daily Log is a sort of Journal where we write our thoughts, memories and keep notes on what we fixed. Our passengers are also welcome to write their impressions. In order to make it easier to find notes on what we fixed or broke, there is an index along the bottom of each page with the major systems (see above) such as Instruments, Plumbing, etc. By circling the system that is discussed on that page the log is much easier to visually search later. I also leave a large outside margin for adding dates, notes etc.  Daily Log – Sheets

Aluminum Screwpost Binders make a robust log book

Finding the right material for the cover of a screw post portfolio cover was a little challenging. First I tried a conventional hardback cardboard binding, but this warped in just a season or two. So I have two suggestions – the rigid  Acrylic Screwpost Portfolio Cover (Vista) which is less expensive and the  Aluminum Screwpost Portfolio Cover (Machina) which is very classy, indestructible, but more expensive and may scratch wood surfaces.

Get Logging

Whether you decide to use some of the resources here, or buy a log book from a chandlery, the important thing is to actually use these logs. The Ship’s Log is a bare minimum requirement for responsible seamanship. The Daily Log is wonderful to look back on and is a great memory jog for writing those facebook or blog posts when you return to the world of internet.

I’ve never heard of an anchoring log book – what purpose is it for? What data do you want to record?


Hi Marie, I just came across your website. It is very nice and lost of great info. I did not ask the original question regarding an anchor log however, I have heard from others that it is a good practice to record some basic info about it like depth of water, method of anchoring (e.g., 1 or 2, Mediterranean Mooring, etc.). I think the idea is then this info can be used for things like planning future trips, maintenance, etc. I hope this helps.

Thanks for the useful logbook pages. It took me a little while to figure out that “init” meant the initials of the person filling in the entry. I still haven’t figured out the meaning of the “Crs” column. What’s it for?

CRS is the course! Sorry – I should have deciphered those!

That makes perfect sense – course. I’m tweaking this by adding a temperature column under conditions. I’m also changing the speed / miles to a dual data set. GPS Speed and GPS Mile and Course Speed and Course Miles. My thought is that tacking back and forth you are building up miles but might not be making many miles along your course. If the GPS / plotting software is running you are likely getting two sets of numbers that might be of interest to record. If you aren’t really going anywhere you might just want to log the distance traveled …  Read more »

Great Info! One question…with your logs the pages appear to be 8.5×11 inch sheets, but the binders you point to are 11×17. What do you actually use? It appears the exact binders you linked to are discontinued…

I use 8.5×11, they may have changed their links. I’ll see if I can find the same product and fix the links. Thanks!

Andreassen Gjermund

Ahoy! Magnificent site you have here. I am reading The Log of the Cutty Sark, and dont understand this: After giving the fix position lat/long – the course always follows, given by three elements f.i. «S. 42˚ W.» I assume S.

Why Keep a Captain’s Log?

A captain’s log is an essential tool for any sailor. A logbook is designed to record important details about your journey, including weather, navigation, and crew information. However, a captain’s log serves several purposes beyond just recording information.

Importance of Accurate Record Keeping

An accurate and detailed record of your sailing journey can help you recall valuable information, such as the best routes to take, wind patterns, and the types of gear you need for future trips. It can also assist you in identifying patterns and trends in your sailing experiences . For example, if you notice that you consistently encounter rough seas in a certain area, you can adjust your route or prepare accordingly for future trips.

Additionally, keeping a captain’s log can help you track your progress as a sailor. You can see how your skills have improved over time and identify areas where you may need to improve further. This can be especially helpful if you are training for a specific sailing event or competition.

Legal Requirements and Regulations

In some areas, there may be legal requirements for sailors to keep a captain’s log. For example, if you are operating a commercial vessel or transporting passengers, you may be required to keep detailed records of the journey. It is important to check your local regulations to ensure you are in compliance.

Even if you are not required by law to keep a captain’s log, it is still a good idea to do so. In the event of an accident or emergency, a detailed log can provide valuable information to authorities and insurance companies.

Enhancing Your Sailing Experience

A captain’s log can help enhance your sailing experience by providing a detailed account of the journey. It can help you remember memorable moments, new sailing routes, and the people you sailed with. In addition, keeping a log can help you stay motivated and engaged with your sailing hobby.

One way to make your captain’s log even more meaningful is to include personal reflections and observations. For example, you could write about how the sunset looked from the deck of your boat or how the smell of the ocean air made you feel. These details can help you capture the essence of your sailing experience and create a lasting record of your journey.

Keeping a captain’s log is an important aspect of sailing. It can help you improve your skills, comply with legal requirements, and enhance your overall experience. By taking the time to record your journey, you can create a valuable resource that you can refer to for years to come.

Choosing the Right Logbook

Choosing the right logbook is an essential step in keeping a captain’s log. Not only does it keep track of important information, but it also serves as a record of your journey and experiences on the water. There are several types of logbooks to choose from, each with its unique features. Here are some key things to look for when selecting a logbook:

Types of Logbooks

Logbooks can be divided into two primary categories: paper and digital. Both types have their advantages and disadvantages. Paper logbooks are simple and easy to use, making them a popular choice for many sailors. However, they can be difficult to read and may not be as durable as digital logbooks. Digital logbooks, on the other hand, are easy to read and can be shared easily; however, they require a device to use and may not be available in all types of weather conditions.

It’s important to consider the type of sailing you’ll be doing when choosing between a paper or digital logbook. If you’re planning on doing extended offshore sailing, a paper logbook may be a better choice as it doesn’t require a power source. However, if you’re sailing in coastal waters and have access to power sources, a digital logbook may be more convenient.

Key Features to Look For

When selecting a logbook, consider the type of information you will be recording and choose a logbook that is designed to accommodate that information. Look for logbooks that have space for recording basic details such as date, time, and location, as well as weather information, navigation information, and crew and passenger information. Additionally, consider the durability of the logbook, as it will need to withstand the elements. A logbook with waterproof pages and a sturdy cover will be a good investment for any sailor.

Another important feature to consider is the size of the logbook. If you have limited storage space on your boat, a smaller logbook may be a better choice. However, if you’re planning on doing extensive sailing and need to record a lot of information, a larger logbook may be necessary.

Digital vs. Physical Logbooks

If you choose to use a digital logbook, be sure to research and test different options. Some popular logbook apps include Deckmaster, BoatLog, and Navily . These apps offer a range of features, from basic logbook recording to advanced navigation tools. However, it’s important to remember that these apps require a device to use, which may not be convenient for all sailors.

On the other hand, if you prefer a physical logbook, consider purchasing one specifically designed for sailors, such as the ASA logbook or the Rite in the Rain logbook. These logbooks are designed to withstand the elements and have space for all the necessary information. They also offer a sense of tradition and nostalgia that many sailors appreciate.

Ultimately, the choice between a paper or digital logbook comes down to personal preference and the type of sailing you’ll be doing. Regardless of which type you choose, a logbook is an essential tool for any sailor and will serve as a valuable record of your adventures on the water.

Essential Information to Record

Recording essential information accurately and diligently is critical to maintaining a useful captain’s log. Here are some of the most important things to record:

Basic Details

Basic details include the date, time of departure, and time of arrival. This information is essential for keeping track of the time spent on the journey and for calculating the distance covered. Additionally, record the name and type of vessel you are sailing on and the name of the skipper.

It is also important to note the purpose of the voyage. Are you on a pleasure cruise, a delivery trip, or an expedition? This information can help you plan your route and make necessary arrangements for the journey.

Weather and Sea Conditions

Weather and sea conditions are critical information to record, as they have a significant impact on the journey’s safety and enjoyment. Include data such as wind speed and direction, sea state, atmospheric pressure, and visibility.

It is important to note any changes in weather or sea conditions, as they can affect the vessel’s performance and the crew’s comfort. For example, if there is a sudden increase in wind speed or a change in sea state, the skipper may need to adjust the vessel’s course or speed to maintain safety.

Navigation and Position

Recording navigation and position information is essential for safety and route planning. Record information such as the course, speed, and position of the vessel and any aids to navigation used.

It is also important to note any hazards or obstacles encountered during the journey, such as reefs, rocks, or other vessels. This information can help you plan future voyages and avoid potential dangers.

Crew and Passenger Information

Record the names and roles of all crew and passengers, as well as any noteworthy experiences they have had during the journey. This information can be helpful for future reference and for assessing the suitability of future crew members.

It is also important to note any medical conditions or special needs of the crew and passengers, as well as any incidents or accidents that occur during the journey.

Maintenance and Repairs

Recording any maintenance or repair required and carried out can help you keep track of the vessel’s mechanical systems and ensure that it is in good working order.

It is also important to note any equipment or supplies that need to be replenished, such as fuel, water, or food. This information can help you plan for future voyages and ensure that the vessel is properly equipped.

By recording all of this essential information in your captain’s log, you can create a valuable record of your journey and ensure that you are prepared for future voyages.

How to Write a Captain’s Log Entry

Writing a captain’s log entry may seem daunting, but using a standard format and writing clear and concise entries can make the process much more manageable.

As the captain of a ship, you are responsible for recording important details about your journey in a captain’s log. This log serves as a historical record of your voyage and can be used for a variety of purposes, including legal documentation, maintenance and repair, and future planning.

Using a Standard Format

Using a consistent format makes it easier to read and interpret the data later. Begin each log entry with the date and time, followed by the basic details, weather and sea conditions, navigation, and position information, crew and passenger information, and maintenance and repair notes.

By following a standard format, you can ensure that your log entries are organized and easy to understand. This can be especially important in emergency situations, where quick access to information can be critical.

Writing Clear and Concise Entries

When writing entries, use clear and concise language and avoid using acronyms or technical jargon. Use bullet points or subheadings to break up the text and improve readability. Keep your entries brief but informative. Aim to record only the most essential information to avoid cluttering the entry with irrelevant or duplicative data.

Remember that the purpose of the captain’s log is to provide a clear and accurate record of the journey. By using clear and concise language, you can ensure that your log entries are easy to read and understand, even by those who are not familiar with nautical terminology.

Including Relevant Details

Include any details that are relevant to the journey, such as interesting events, observations, and wildlife sightings. Remember that the captain’s log should provide a comprehensive record of the journey, including any lessons learned, mistakes made, or changes in plans.

By including relevant details in your log entries, you can create a more complete picture of your journey. This can be especially useful for future planning or for sharing your experiences with others.

How to Become a Cruise Ship Captain

Sailboat Maintenance Checklist

Sailboat Maintenance Checklist

Whether your sailboat is stationary for a long time, or whether you live and travel with it, there are several key things to keep an eye on. Regular maintenance of your sailboat will ensure more years of use and better performance. Furthermore, your sailboat will be safer and it will keep its value longer. Below you’ll find a checklist for routine mission-critical checks. Some of these checks have to be performed both daily and monthly. Others require monthly and annual checks, but always make sure to inspect everything, thoroughly. Follow the steps of the list and ensure trouble-free sailing.

The engine of your sailboat is something that requires a lot of care and attention. Inspect regularly the condition of the engine and look for corrosion, as well as make sure that the outboard motor is securely in place. Daily maintenance of the engine consists of:

  • Check the engine’s oil level.
  • Check the belt tension.
  • Transmission fluid level.
  • Inspect pulleys as well as the alignment.
  • Alternator and water pump belts have to be tight.

And now we’re moving on to the monthly maintenance of the engine which includes:

  • Change the oil and filter of the engine.
  • Clean the thru-hull.
  • Clean the siphon break.
  • Fill up coolant and antifreeze if needed.
  • Check pump, impeller, and raw water strainer.

Finally, let’s see the annual maintenance of your sailboat’s engine:

  • Test the batteries.
  • Check the diesel tank for damages.
  • Inspect the shaft and propeller.
  • Change primary and secondary fuel filters.
  • Bleed the fuel system.

Check the Bilge and Bilge Pump

The bilge is situated at the bottom part of the sailboat and collects excess water. The bilge pump is the piece that removes water from the bilge. If the bilge pump is damaged, your sailboat can even be sunk! In order to keep yourself and your boat safe, check the pump hoses for debris that could cause clogs. In case you find a leak, the first thing you should do is to taste the water. Is it freshwater or saltwater? So, every few days survey the bilge for oil, water, or fuel leaks. Moreover, it’s important to lift a central floorboard often just to ensure that the bilge is dry. Leaks can be caused by different areas. For instance, leaks that come from holes in the deck, loose hatch seals, or improperly sealed windows.

Yacht Maintenance Checklist

>>Also Read: Common Sailboat Problems and How to Fix Them

Always inspect probable damages to your sailboat, even if it’s in a well-maintained condition. It’s recommended to make monthly and yearly checks to make sure it stays in perfect condition. Firstly, inspect the hull, keel, and rudder and look for any damages, cracks, and blisters. Then, make sure that the drain plugs are in place. Apply gel coat restorer or a rust inhibitor to the scratches or to the rusting of your sailboat’s bodywork. Moreover, you will also need to remove your sailboat from the water, once a year. It’s easier to do this during the winter months and although this can be a costly thing to do, is really worth it. Like this, you’ll get a better image of the hull’s condition and fix anything that needs repair. Finally, remember to annually carry out anti-fouling and any re-painting or zinc replacement.

Raw Water Strainers and Freshwater Levels

Don’t forget to check your seas strainers! If you’re running your generator, heat/air conditioning, or anything that requires saltwater or raw cooling system to function, you might want to surveil your strainers. Furthermore, inspect the water flow on all of the raw water cooling systems. You have to see an easy flow of heating, Genset, refrigeration, and aircon cooling water out of the system. If the freshwater system, which is pressurized by an accumulator tank gets too low, then it throws the whole system out and thus it will not be working properly. So, it’s imperative that you never let your water tanks empty.

As for the electrical system it is recommended to check it every month. Check the condition of the wires, if they’re neatly secured, dry, and inspect their casings to see if they are intact. However, there are some sailboats that have their generator running periodically to charge them up. So, keep an eye on your battery’s charge levels. Also, the electrical lines must be in good condition to keep the electrical system on your sailboat up and running. Any damaged lines could provoke a fire hazard. To prevent electrical lines from erosion, remember to keep them clean, and use a digital multimeter to make sure everything’s working properly.

Without the battery, which is the heart of your sailboat, the engine won’t start, nor the electrical components will work. So, take good care of the battery and check it once a year, or more often, i.e. during the boating season. Keep in mind that batteries naturally degrade over time, so this is a must task to perform. You can check the battery’s charge with a digital multimeter, and the connections for corrosion. Moreover, test the batteries and check if they’re clean and dry. There are sailboats that have solar and wind power that continuously tops up the batteries. Other sailboats depend on having the generator running periodically in order to charge them up.

In case you’re running the generator you will need to check its vitals at least once a week. So, check the oil, belt, water level, and inspect for leaks and loose connections. You can see the leaks easier if you keep the Genset clean.

Oil and Filter

Remember to regularly change the oil and oil filter. In case you don’t, then it is possible to provoke damage to the engine parts. In order to change the oil, let the engine run for about seven minutes, then turn it off. Subsequently, place a container under the drain plug. Take out the drain plug and loosen the screw that is located above. Then, let the oil drain out for about 30 minutes. During this process change also the oil filter. After the oil drains out, replace the drain plug and tighten the screw. Finally, fill the engine with the proper oil.

Fridge and Freezer Temperature

The effectiveness of a fridge often depends on the temperature of the sea. Many boat refrigeration systems get a charge over time which makes them less effective. Therefore they slowly reduce the temperature gauge. So, it is recommended to change the temperature gauge at least once a week. The temperature of the fridge has to be below 5 degrees and the freezer below freezing.

Sails and Rigging

Sails and rigging have to be checked at least once a month. Firstly, look out for any chaffing where the headsail sheets attach to the clew, and also to the traveller and boom vang. Secondly, examine thoroughly if there’s any wear on the mainsail. Then, check if the cotter pins and shroud are in place and in good condition. Finally, make sure that the turnbuckles and pelican hooks on the lifeline are in good condition.

Summary- Maintenance List

Your sailboat’s maintenance needs to be taken seriously. When you’re regularly maintaining your sailboat, you also ensure its life spanning. Some basic items that require constant maintenance are the generator, the battery, the plumbing, the bilge, oil, and the fridge and fluid levels, among others. However, there are others that require monthly or yearly maintenance, such as the engine, the electrical system, the sails and rigging, the propeller, zippers, hinges, upholstery, etc. In case you can’t repair or check the condition of these parts, then consider contacting a professional to help you with the maintenance process.

Boat maintenance log

by Simon Jollands | Boat Maintenance , Preparation , Yacht ownership

sailboat maintenance log

Keeping a boat maintenance log is an ideal way of reminding owners what needs to be done to a boat and when. Read on for some tips, advice and a sample maintenance log.

However keen you may be to work on your boat, organising yourself can be challenging on occasions. Planning routine boat maintenance in advance can really help you in the long term.

Getting organised

If you are thinking of doing the bulk of the work yourself then it is advisable to be realistic about how much work needs to be done and approximately how long it is going to take. The winter weather can often put a spanner in the works so you may need to build in some flexibility. For those fortunate enough to have friends or family who are happy to give you a hand, the sooner you can firm up dates in diaries for doing this work the better. Remember to give them plenty of advance warning, preferably when the sun is still shining.

Even if you are not going to do the routine maintenance work yourself due to the pressure of work, physical impediment, or because you can afford not to, then you still need to do some planning well ahead of time. This means speaking to your boatyard early on and explaining what tasks need to be done and when. It is a little foolhardy just to take the boat ashore at the end of the season and then three months later ask the yard to do all the maintenance just before you plan to go afloat in the spring. Not a good plan.

sailboat maintenance log

Doing the work yourself

Begin by checking through the boat’s maintenance history, noting when work was done in previous years, how much it cost and estimating how long each task took.

Make a list of the materials and tools you will need for each task coming up and remember to keep a note of what you spent on materials and where you bought them. With boating, it always pays to shop around to get the best price for parts.

While your local chandlery might be your favourite shop in the world to browse in, if you are after non-specialist products, such as sponges, brushes, paint rollers, thinners, solvents and tape, you will most likely find similar items in large hardware stores at a fraction of the price. Also, if you are really organised, then buy enough materials to last for a whole season and you will save yourself both time and money in the long run.

Maintenance log spreadsheets

There are some excellent downloadable boat maintenance log spreadsheets available and one in particular I would recommend is produced by Viki Moore of Astrolabe Sailing see www.astrolabesailing.com . Viki’s spreadsheet collates all kinds of information which is boating related including maintenance, boat details, spare parts, annual budget, personal inventory, passage log and more.

Viki’s boat maintenance worksheet is designed to work as a reminder of work to be done as well as a record of what has been done in the past. There are columns to add the parts required, their part number, measurements and other details to make life easier when you need to place orders and plan the work.

Below are some extracts taken from Viki’s maintenance log that gives an overview plan of the routine maintenance that needs to be carried out annually on a typical mid-size cruising yacht.

Should you decide not to keep a computer based maintenance log, it would still be a good idea to make a plan of what routine maintenance needs to be done through the year, noting the jobs that can be done only when the boat is hauled out. We hope the checklists above will help you get started.

Boat And Trailer Maintenance Checklist


Take care of the boat, trailer, and engine and the chances of a problem occurring on the water or the road will be minimized. Here's what you need to know.

Changing oil in lower unit

Whether you do it yourself or leave it to the pros, routine maintenance is essential to keep your rig in tip-top shape.

So you're a new boat owner. Your pristine center-console sits proudly in your driveway, the outboard shining brightly in the sun, and even the trailer is sleek and polished. How can you keep it at least close to looking and performing as it does now? Maintenance is the key.

But if you're not mechanically inclined, how can you properly care for your new rig? If you're all thumbs, budget in some bucks for dealer maintenance. In this case, it's probably best for both you and your boat if you leave the mechanical details to the pros. You can, however, perform all the tasks that don't require technical expertise. Such tasks as keeping fittings and moving parts lubricated, cleaning and waxing the finish, checking the drive lubricant and engine oil, making sure that fishing line isn't wrapped around the prop shaft — these are all examples of simple skills a responsible boater should learn, especially to protect his or her investment. While boats have never been cheap, they seem to be more expensive than ever when compared to the average paycheck, so it's smart ownership to make sure that all is up to snuff.

To help you out, we've created a simple Timeline and Maintenance Chart, one that works for DIYers and tech-savvy boaters alike. Refer to the chart to check maintenance items before every outing and at every 20, 50, and 100 hours of use. Seasonal boaters should consult the chart before every layup. With our chart as your guide, your rig will stay like new for longer and command top price at resale or trade-in time, particularly if you keep records of what you've done and when. The chart is the suggested schedule, although some boats may require more frequent checks. If in doubt always follow the manufacturer's recommendations for your particular boat, engine, and trailer.

Click on checkmarks in the chart below to watch our how-to videos.

Always follow recommendations in manual first Every Outing Every 20 hrs. Every 50 hrs. Every 100 hrs. Before Layup Video

Maintenance log.

On our previous boat , we were (just barely) able to remember when all mechanical systems needed service as the hours mounted and time passed. But that system broke down when we got the current boat. There are far more systems, many of the intervals vary greatly, and when running offshore, up-to-date service is even more important. We knew we needed some form of automation to help track all the systems and their varying maintenance schedules.

Many approaches to maintenance logs exist and, in fact, entire businesses have been built on tracking service items and notifying when service is needed. We are fairly hands-on and, for long-range cruisers, even though it takes time to understand all the systems, this feels like time well spent. One thousand miles from shore, there won’t be someone else flying in to help. A good approach for maintenance and service tracking is to use a database, and drive all tracking and notification from a software application built upon the database. We still may take this route someday in the future, but didn’t feel like taking the time to write this complete application up front. Instead we elected to use an Excel-based spread sheet model. Just as many exotic financial instruments are first implemented in spreadsheets and only migrate to full applications when they are successful and need to scale, we went first to Excel. It’s actually working out remarkably well.

The log contains one entry per service item, where each item has an associated number of hours and/or number of months between service intervals. For example, in the screenshot below, the cells highlighted in blue indicate the main engine oil and filter are due to be changed every 6 months or 375 hours. This information is entered per service item, one time only. Service intervals can be expressed in only hours or only months. In the screen shot below, the start batteries need to be tested every 12 months, but have no hour-based service interval, and the harmonic balancer should be changed every 8,000 hours, but has time-based service interval.

The top of the sheet lists the current number of hours for each piece of equipment. For example, the number of main engine hours, 5,208, are highlighted in yellow below. When we update the number of hours on a piece of equipment, the log tells us when the next service is due in 1) hours for each item that depends on that piece of equipment and/or 2) months based on the current date. In this case, the cells highlighted in green indicate that the main engine oil and filter are due to be changed in 4 months or 93 hours.

Service items

As service work is performed, we enter the date and/or number of hours on the associated equipment when the work was done. In the screen shot below, the main engine oil and filter were last changed on 2015/01/09 at 4,926 engine hours. This data, combined with the current date and the main engine hours at the top of the spreadsheet, are used to calculate the months and/or hours left before the next service is required.

Work done

The most useful aspect of the spreadsheet is the highlighting of a service item near due or overdue. In the screenshot below, we’ve incremented the number of main  engine hours by 200 to 5,408. The main engine oil and filter change is now overdue by 107 hours, and that service item now shows in red. In addition, the service item to clean the air filter is orange. This indicates that the service item is near due, but is not yet overdue. The orange coloring uses the warning thresholds that we’ve highlighted in blue below. In this case, we want to display a service item in orange if it is within 1 month or 50 hours of being due.

Service items are grouped based on the equipment they depend on, if any, and the warning threshold. For the wing engine below, we have a warning threshold of 1 month and 15 hours. We could also choose, for example, to add another main engine group with a different warning threshold, such as 25 hours.

Warning thresholds

When a service item is near due or overdue, the normal way to change the text color back to black is to perform the service and update the date and/or associated equipment hours when the work was done. But sometimes this either isn’t feasible or necessary. That is where the Acknowledge column comes in. The screenshot below shows that the stabilizer fin zincs are 37 hours overdue for a change, but that’s best done in the yard. So we’ve entered “ACK:Yard” there and that changes the color from red to green. This still highlights the item as not done, but showing it in green will keep it visually separate from items that we really do want to handle as they become due. The “ACK:” portion of the text is all that is necessary for the acknowledgement, anything after that is for descriptive purposes only.

Extending a due date is different from an acknowledgement. The bottom cleaning currently is due after 3 months, but on inspection it’s still pretty good, so we’ve entered “M:1” below to extend the due interval by 1 month. In Seattle we used to change our zincs every 6 months.  But since we’re not in marinas as frequently, we’re able to go longer as we’re no longer supporting other boats in the marina. So we instead check the zincs periodically and extend the due interval if they are in good shape. Below we’ve extended the due interval for the zinc change by 12 months using “M:12”, and it shows as 11 months overdue. The 12-month extension makes the zinc change due in April of 2015, 1 month from now. Since that is within the 1-month warning threshold for that service item group, the zinc change shows in orange. We’ll check the zincs soon and either change them or extend the due interval again.


In a similar vein, we also created an expiration schedule spreadsheet for non-maintenance items that we need to track, such as renewing our passports or drivers licenses. These are grouped based on the amount of lead-time needed to process each item.

Expiration schedule

The text color changes are implemented using conditional formatting. We have added extra columns, normally hidden, that extract some of the data from the service items plus their warning threshold and base hours. This puts the relevant data for a service item on a single row and simplifies the conditional formatting formulas.

James, Jennifer,

This is great, I just adapted it for our GB42 and it will be super handy to keep on top of the many systems that are hidden our of sight.

That’s great. We’re glad it looks like it’ll work for your Grand Banks.

Is there a reason for some of the cells having their own special conditional formatting – cell b22, b105, b100? Here are all of the conditional formatting cells. I am sure I will figure it out, and will maybe just stick with the last two conditional formula. I realize this is not turn-key and you have to understand Excel really well. I really like the fact that it is Excel and not a fancy application that could go away someday!

Main =IF(ISBLANK(J22) = FALSE, 1, 0) b22 – drain water off fuel filter $B$22 Main =IF(OR(IF(ISNUMBER(C22),((NOW()-F22)/30>C22),FALSE), IF(ISNUMBER(D22),((O22-G22)>D22),FALSE)),1,0) $B$22 Main =IF(OR(IF(ISNUMBER(C22),((NOW()-F22)/30>C22-M22),FALSE), IF(ISNUMBER(D22),((O22-G22)>D22-N22),FALSE)),1,0) $B$22 Main =IF(ISBLANK(J105) = FALSE, 1, 0) b105 – lubricate bicycle chain $B$105 Main =IF(OR(IF(ISNUMBER(C105),((NOW()-F105)/30>C105),FALSE), IF(ISNUMBER(D105),((O105-G105)>D105),FALSE)),1,0) $B$105 Main =IF(OR(IF(ISNUMBER(C105),((NOW()-F105)/30>C105-M105),FALSE), IF(ISNUMBER(D105),((O105-G105)>D105-N105),FALSE)),1,0) $B$105 Main =IF(ISBLANK(J100) = FALSE, 1, 0) b100-104 top off $B$100:$B$104 Main =IF(OR(IF(ISNUMBER(C100),((NOW()-F100)/30>C100),FALSE), IF(ISNUMBER(D100),((O100-G100)>D100),FALSE)),1,0) $B$100:$B$104 Main =IF(OR(IF(ISNUMBER(C100),((NOW()-F100)/30>C100-M100),FALSE), IF(ISNUMBER(D100),((O100-G100)>D100-N100),FALSE)),1,0) $B$100:$B$104 Main =R10 $B$57:$B$58,$B$71:$B$79,$B$48:$B$53,$B$83:$B$99,$B$37:$B$44,$B$10:$B$22,$B$26:$B$33,$B$62:$B$67 Main =IF(OR(IF(ISNUMBER(C10),((NOW()-F10)/30>C10+P10),FALSE), IF(ISNUMBER(D10),((O10-G10)>D10+Q10),FALSE)),1,0) $B$57:$B$58,$B$71:$B$79,$B$48:$B$53,$B$83:$B$99,$B$37:$B$44,$B$10:$B$22,$B$26:$B$33,$B$62:$B$67 Main =IF(OR(IF(ISNUMBER(C10),((NOW()-F10)/30>C10-M10+P10),FALSE), IF(ISNUMBER(D10),((O10-G10)>D10-N10+Q10),FALSE)),1,0) $B$57:$B$58,$B$71:$B$79,$B$48:$B$53,$B$83:$B$99,$B$37:$B$44,$B$10:$B$22,$B$26:$B$33,$B$62:$B$67

I didn’t check the expiration schedule spreadsheet—I’d forgotten there were two.

I’ll fix both spreadsheets tomorrow so that they’re both absolutely error-free.

On your question about =R10, that is referring to the value in hidden column R. R10 will be 1 if the J10 in the Acknowledge column has a value starting with “ACK:” in it, and that will show the item in green. When a service item is near due or overdue, the normal way to change the text color back to black is to perform the service and update the date and/or associated equipment hours when the work was done. But sometimes this either isn’t feasible or necessary. That is where the Acknowledge column comes in. Entering “ACK:xxx”, where xxx can be any text, changes the color from red to green. This still highlights the item as not done, but showing it in green will keep it visually separate from items that we really do want to handle as they become due. The “ACK:” portion of the text is all that is necessary for the acknowledgement, anything after that is for descriptive purposes only.

I am not sure if my comment got in or not – regarding the maintenance spreadsheet has one conditional formula that I am not sure what the function is:

=R10 ( on the range: $B$57:$B$58,$B$71:$B$79,$B$48:$B$53,$B$83:$B$99,$B$37:$B$44,$B$10:$B$22,$B$26:$B$33,$B$62:$B$67)

I will try to figure it out, but the sample expiration spreadsheet has REF# in some of the formulas ( which means the formula references cells that no longer exist). I am trying to figure out what the conditional formatting REF# cells should be referring to.

Sorry you’re having trouble with the spreadsheet. I don’t see any fields display REF#–is it possible you’ve edited/cleared something? Note that there are some hidden columns M-R that the other formulas reference–you might have accidentally deleted them.

If that isn’t the problem, could you tell me the row/column of one of the cells where you see REF# and the formula in that cell?

First thank-you so much for responding. The spreadsheet is amazing!! I have been able to dive deep into the logic and how the spreadsheet works to have it all work perfectly for me! Now I am moving onto the maintenance schedule!

The REF# references were in the Conditional Formatting for the worksheet. I was able to delete the rules that have “REF#” in them ( the REF means they were were referring to fields that do not exist). This was a problem with the base .xlsx before I made any changes at all.

Thank-you for sharing your work!! We just bought a new-to-us boat. I hope to be really good about keeping track of all maintenance and upgrades. This really paid off well for the motorcycle I just sold, although simpler records :)

The posted spreadsheet has no #REF errors in the Conditional Formatting. It’s easy to change something and create one though. The best way to make changes to the spreadsheet is one at a time, looking for any problems as you go, and undo the change if you get an error.

Glad you got it working, and hope you enjoy your new boat.

You can see the #REF in the conditional formula – here are all of the conditional formulas. Look at line 6. I hope this helps, but I am all set with the spreadsheet with making changes. It is great!!! Thank-you.

Sheet Formula Range ExpirationDates =IF(ISBLANK(F8) = FALSE, 1, 0) $B$8 ExpirationDates =NOW()>C8 $B$8 ExpirationDates =IF(ISBLANK(F6) = FALSE, 1, 0) $B$14,$B$6:$B$10,$B$18:$B$20 ExpirationDates =(C6-NOW())/30 <= 0 $B$14,$B$6:$B$10,$B$18:$B$20 ExpirationDates =(C6-NOW())/30#REF!),FALSE), IF(ISNUMBER(#REF!),((#REF!-D14)>#REF!),FALSE)),1,0) $B$14,$B$18 ExpirationDates =IF(OR(IF(ISNUMBER(#REF!),((NOW()-C14)/30>#REF!-L14),FALSE), IF(ISNUMBER(#REF!),((#REF!-D14)>#REF!-M14),FALSE)),1,0) $B$14,$B$18

I should have added that the formulas are what came directly with the sheet provided in your link. This is without me making any changes at all. But again, I am all set, and love what I have working with my expiration sheet – all works great!

Hello James, Nice spreadsheet and thank you for sharing. I just bought a sailboat with a diesel engine. You say that “…When we update the number of hours on a piece of equipment, the log tells us when the next service is due in 1) hours for each item that depends on that piece of equipment and/or 2) months based on the current date. In this case, the cells highlighted in green indicate that the main engine oil and filter are due to be changed in 4 months or 93 hours…”

I am looking for how updating C1 cell automatically updates H14, but I do not see C1 referenced in the H15 formula. Is C1 value used just for manual tracking?

Also, what is the 4.34 multiplier referencing or correcting for?

Thank you!!

Glad you find the spreadsheet helpful.

The hours at the top (C1 etc) are used for the calculation of “Hours left” in column I (based on the values in hidden column O).

The calculation for “Weeks left” in column H only depends on the last service data and the “Months due” value in column C, so won’t use hours from C1 etc. The 4.34 multiplier is to convert from months to weeks.

Excellent, thank you!

SO nice of you two to share this! I was going to sit down and build something like this from scratch, but you just saved me hours. : )

Good to hear. I hope it works well for you.

My version of your spreadsheet (modified for my vessel) seems to have lost its ability to color code items based on date timing (yellow, red, etc.). I cannot find the location for the conditional formulas that control the text colors. Could you please clarify where I can find the formulas?

The color coding is based on the values of hidden columns M-R. See the bottom of this blog post for an explanation with a screenshot.

' src=

just found your maint log schedule. tried to import it onto my iMac and a number of formula wouldn’t transfer , any suggestions ? Regards Paul

It sounds like some incompatibility between the Excel or whatever you are using on your iMac. When you say “import” it sounds like you might not be using Microsoft Excel. If you aren’t, that or Office365 should open the spreadsheet without problem. If you are using Microsoft Excel might try latest patches or installing the new version. If that isn’t practical, Google docs will probably read the spreadsheet: https://www.google.com/sheets/about/ .

James, just found this blog and your maintenance spreadsheet. I’ve been looking for a good tool for tracking maintenance on our 34′ PDQ power catamaran. Question… could you please clarify to purpose of the “Base Hours” column?

Hi Mac. Glad to hear the spread sheet might be useful to you. The “base hours” column is explained in the blog: “We have added extra columns, normally hidden, that extract some of the data from the service items plus their warning threshold and base hours. This puts the relevant data for a service item on a single row and simplifies the conditional formatting formulas.” ( https://mvdirona.com/2015/03/maintenance-log/ ).

We’re just picking up the current engine hours from the top left hand corner of the spread sheet and repeating it as a hidden column. This just makes it easier to code the rest of the spread sheet and can be and should be ignored. If you just copy full rows or delete full rows, everything will work fine. Base hours is essentially just a programming convenience to make the spread sheet simpler to write.

James, thanks for your reply. Another question… what do you do for a maintenance “log”? (a chronological history)

The maintenance log probably should have been done using a database application but the excel version is easy to use and serves to remind me to do what needs to be done. We have a separate boats log where I keep all boats movements, consumption, uses, anomalies, events, and maintenance. The excel spreadsheet reminds to get the work done and the ships log is where the record is kept.

Thanks for providing your maintenance log. We are the new owners of a Kadey Krogen Whaleback and are slowly getting our heads wrapped around all the systems. Your log will be a great help in keeping things maintained properly. Do you have an example of your Ships Log that you’d be willing to share? I did search the blog and couldn’t turn it up.

BTW, I really enjoy your blog. Very inspiring to us as we start to plan our travels.

Our ships log isn’t very automated. We just use a word document with a computer generated trip summary that we just copy into the log. More detail on it here: https://mvdirona.com/2020/08/ships-log/ .

Hi James Thks for your entry – valuable and highly useful. I am presently considering a secondhand 47′ and would be interested in stalling the Matron equipment here. Have received the ‘N2K Builder_UM_1 116’ and wonder if you are willing to post your DIRONA details here as well. It would give me a good comparison and be of great help in evaluating details and cost. Was your installation done from the PAE factory or did you do it yourself?? Your are welcome to reply by mail directly. Thks for your entries -interesting and great for a NordhavnDreamer. Best regards Erik/Denmark

Hi Erik. Sure, I’m happy to post more data on the Maretron system but I don’t have a current n2kbuilder example. What we could post is the n2kanalyzer output showing all the attached devices and the underway and at rest screens. I’ll plan to do a blog posting with that data — let me know if that will cover your interests.

The NMEA backbone was installed at the yard but all devices where attached since delivery of the boat. I don’t think I gained much in running the backbone NMEA cable at the boat yard. Later this week, I’ll get a blog post up with the data you are after.

Hello James – great will look forward to this and am convinced this will cover for the time being. Will test the builder meanwhile..

James, Thanks for posting these spreadsheets. They are just what I am looking for as I start the maintenance plan for Sorpresa. This summer we’ll leave SFO and up for Desolation Sound. Old news for you but we’ve never been! Kind regards, Pete PS> Glad you missed the Sydney storms.

Glad to hear that the maintenance log will work for you. Enjoy Desolation Sound, we have been up there many times and really enjoy it. Our favorites were sunny winter days where the weather was nice, it’s comfortable on deck, the circling mountains are snow capped, and there is not another boat for miles. It’s like a trip back in time to a period when far fewer boats visited.

While you are up that way, you should get the Waggoner Cruising guide ( http://www.waggonerguide.com ) and, if you like to get a bit off the beaten path, our cruising guide might help as well: http://www.amazon.com/Waggoner-Cruising-Guides-Secret-Coast/dp/0935727299
