What is a Yacht? History, Types of Yachts, Styles, and Sizes

In this article, we explain the definition, history and origin of the word yacht, and break down some of the more common types of yachts along with various styles and sizes.

Yacht Definition & Origin

The word yacht comes from the Dutch word “jacht”, which means to hunt, and refers to the quick and lightweight sailboats the Dutch navy used to pursue pirates and other enemies in shallow waters. Today, the word takes on a very different meaning. While there is no strict definition of the word today, a yacht is generally considered as a boat used for pleasure, whether you’re cruising open waters, racing or island-hopping for the weekend. Typically, we consider a boat to be a yacht if it has an overnight cabin onboard, is more than 33 feet long, and generally looks nicer than your average vessel.

Pleasure boats have been around for hundreds of years, which is no surprise when you consider our options for transportation around that time. Without planes, cars, bikes or scooters, humans turned to the one form of transportation they knew well for pleasure – the ship.

Sailing Yacht History

Sailing yachts have been a thing since at least the beginning of the 1660s in Europe, when King James of England commissioned a sailing yacht for his son Henry, the Prince of Wales. But it was Charles II, the Kind of Scotland, who brought the term “yacht” into the mainstream after spending time exiled in the Netherlands. Once Charles got home, he began commissioning royal yachts left and right.

Steam Yacht History

Steam Yachts also have quite the history, which started as massive and luxurious sailing yachts with steam auxiliary engines. These yachts were much larger, and carried full crews complete with a cook, captain, engineer, stewards and deck hands. By the late 1700s, screw propellers were installed and the engines became far more efficient. Eventually, compound engines came about and persisted until the internal combustion took over.

Power Yacht History

Powerboats with 4-stroke gas engines were first developed by Nicolaus Otto and Gottlieb Daimler in 1876. Then in the 1900s, diesel engines became the more popular option because of their lower cost and improved reliability.

Yacht Types

Today, yachts fall into one of two general categories – sailing yachts and motor yachts.

Sailing Yachts

A sailing yacht is a leisure craft that relies on its sails for the primary method of movement, made from natural, synthetic or carbon fibers. Sailing yachts are split into two main categories: cruisers and raisers.

Cruising Yachts

A cruising yacht is designed for comfort above anything else. These yachts are ideal for overnight and lengthy journeys, typically equipped with all the comforts of home, including full kitchens (galleys), bathrooms (heads) and beds. They’re also designed to be slightly easier to maintain.

At the smaller end, we have what’s called as a “trailer sailer”. These yachts are generally shorter than 25 feet, and can be pulled by the average car. But anything shorter than 33 feet is considered a small sailing yacht. The next level is 33-45 feet, referred to as near-shore yachts. Offshore yachts are the largest category, including vessels larger than 45 feet.

Racing Yachts

A racing yacht is designed with performance top of mind, rather than comfort. World Sailing, the governing body for the sport of international sailing, recognizes 11 different classes of sailing yachts, but each share some general characteristics.

On a racing yacht, aerodynamics is prioritized. These yachts come in a variety of shapes and weights, but performance is the underlying motivation for all. Similar to aerodynamics but underwater, hydrodynamically efficient hulls allow boats to pull through the water with minimal drag or extra motion. Finally, for peak performance, these sailing yachts typically use full-battened Kevlar or carbon fiber sails.

Motor Yachts

Motor yachts come in all shapes and sizes, built with a variety of different materials. Generally speaking, they range from 30-130 feet in length, but there are superyachts out there exceeding 500 feet (that’s over 150 metres!).

The hull of a motor yachts comes in three basic styles. A yacht with a full-displacement hull moves the water up and away, creating waves. These boats have the potential to be plenty powerful, but their speed is limited. Semi-displacement hulls are slightly faster, because they’re able to partially rise above the water. Last are the yachts with a planing hull. These yachts are the fastest, because of a flat underside and enough power to lift them onto the surface of the water.

The majority of modern motor yachts have at least one diesel engine. A boat with two engines is certainly more expensive, but well worth it when you consider the reliability and increased handling/performance.

When it comes to motor yacht styles, there are many. Here’s a brief introduction to a few different motor yacht styles:

• Sport Motor Yacht : These powerful crafts are built with a semi-displacement and planing hulls, making them fast boats great for weekend adventures and short trips.
• Trawler Motor Yacht : A trawler is known for its more traditional style with a displacement hull, designed for medium distance passage-making.
• Cruising Motor Yacht : A cruising yacht is built for comfortable longer distance travel, equipped with a displacement hull.
• Expedition Yacht : Similar to a cruising motor yacht, expedition yachts are built with a displacement hull for long distances, but these crafts specialize in passage-making in remote areas.
• Mega Luxury Yachts : The mega luxury yachts is what you see and hear about on TV and in magazines. They’re hundred of feet long, designed for dozens of family and friends, and reserved for the super-rich.
• Sports Fisherman Yacht : These yachts have semi-displacement or planing hulls for quick fishing trips where you need to be able to move well. On a sports fisherman yacht, there will also be extra space for fishing gear and large fish.
• Lobster Yacht : A lobster yacht is similar to but quicker than a trawler, built with a semi-displacement or planing hull. These yachts get their name from their unique style – looking like classic Maine lobster boats.

Yacht racing is one of the most popular activities associated with yachts, and it has a long and storied history.

Yacht racing dates back to the 1800s and has been a popular pastime ever since.

The sport is often divided into two main categories: offshore and inshore racing.

Offshore racing involves navigating the open waters of the ocean, while inshore racing is confined to the waters near shore.

The History of Yachts

The term yacht has been around since the 1600s, and it has come to represent a broad range of luxurious recreational boats.

The word itself is derived from the Dutch term jacht, which translates to hunt.

In the 1600s, yachts were used for military purposes, such as scouting and patrolling.

Over time, however, the term yacht has come to refer to any large, luxurious recreational boat.

Modern yachts are typically larger than other recreational boats, and range from modest day-sailers to luxury mega-yachts with all the amenities of a home.

Yachts are typically crewed by professional or paid crew and can be used for activities such as fishing, cruising, racing, and even as a floating holiday home.

The evolution of the yacht has been quite remarkable.

In the late 1800s and early 1900s, yachts were primarily used by the wealthy and elite to show off their wealth and status.

Yachts of this era were often quite elaborate and ornate, with richly decorated decks, lavish interior spaces, and even an onboard orchestra.

As technology improved, so did the capabilities of yachts.

In the late 1920s, the modern sailing yacht was invented and became the norm, allowing for a more comfortable and efficient sailing experience.

In the mid-20th century, motor yachts were developed, making navigation and speed much easier.

By the latter part of the 20th century, yacht builders began to focus more on luxury and comfort, with modern yachts featuring amenities such as spas, fitness centers, multiple decks, luxurious cabins, and more.

Today, yachts are still seen as a symbol of wealth and status, and there is a great deal of competition in the luxury yacht market.

There are many different types of yachts to choose from, from modest day-sailers to mega-yachts that can cost millions of dollars.

Yacht definitions: What is a yacht? And does it need to have sails?

• Top stories

By far the most common question we get asked here at Motor Boat & Yachting is ‘how can you call that a yacht if it doesn’t have sails?’ Here we explain why a boat doesn’t need sails to be called a yacht...

What’s in a name? Quite a lot if you’re a yacht! Not only are the names of yachts a source of endless amusement, but by defining your boat as a yacht in the first place, you’re setting up certain expectations.

Yacht definitions: A brief history

Whilst boating for fun dates back to Ancient Egypt and possibly even further than that, the word yacht comes from the Dutch ‘jachtschip’, which means hunting ship. Jachts were originally a class of sailboat used in the 16th century to hunt down enemies of the Dutch Republic.

However by the 19th century the term ‘yachting’ had developed to mean recreational boating in general, and with the advent of steam boats, sails were no longer the only method of propulsion available to Victorian yachtsmen.

In the early 20th century (1904 to be precise), our humble magazine was launched under its original title The Motor Boat , but by the 1950s the ‘& Yachting’ suffix had been added to refer to the general pastime enjoyed by motorboat owners. We even reviewed the occasional motorsailer for those who liked to enjoy the benefits of both power and sail.

Today’s Motor Boat & Yachting is dedicated purely to powered leisure vessels from 25-125ft with the occasional foray above and below that when interest dictates. Current editor Hugo Andreae insists that he is ‘terminology agnostic’ saying, “I’m not bothered whether people refer to their boats as yachts, cruisers, power boats or gin palaces just so long as they enjoy using them. But for the record my 22ft Karnic is definitely a gigayacht!”

Editor Hugo’s Karnic 2250 is his family’s pride and joy, but should it be called a yacht?

What makes a yacht, a yacht?

Some would argue that a yacht has to have sails, and as we’ve seen, that was originally the case, but we here at Motor Boat & Yachting beg to differ, as its common to refer to large motorboats as motoryachts, superyachts or even megayachts without any expectation that they would have sails.

Others assert that a yacht should have to have a cabin in order for it to be fully considered a yacht, or that it has to measure at least 10m in length. If that’s the case then some longer narrowboats could be technically considered as yachts, although you’d be hard pushed to find anyone who agrees with that definition.

The final test for something to be considered a yacht is harder to pin down, but it is generally accepted that all yachts have to have a certain aesthetic or architectural appeal in order to earn this haughty moniker.

Whether a boat is worthy of being called a yacht is clearly subjective, but there’s one thing we won’t budge over – it certainly doesn’t have to have sails!

If it’s sailing yachts specifically that you’re interested in, you won’t find many of them here, but we can heartily recommend our sister titles Yachting Monthly and Yachting World , who know much more about them than we do.

Bigger yacht definitions: Superyacht, megayacht or gigayacht?

Beyond the simple term yacht, there are a few other yacht definitions worth clarifying. The most commonly used of which is superyacht .

The debate still rages over what constitutes a superyacht. Any pleasure yacht with a load line length of 24m or more (not length overall or waterline length as is often misquoted) and a gross tonnage of 80GT is classified as a Large Yacht under MCA coding rules, causing a number of additional regulations to kick in, most crucially the requirement for the skipper to hold a commercially endorsed Yachtmaster Offshore Certificate. This is the closest thing to a technical definition of a superyacht.

At 180m Azzam is currently the largest yacht in the world, but an 183m gigayacht called REV is currently under construction in Norway. Photo: Wikimedia Commons

However, while this used to mean most leisure boats with an overall length (LOA) of 80ft or more fell into the Large Yacht category, yards have become so adept at designing bigger boats with a load line length of just under 24m that many craft with an LOA of 90ft or more still count as regular pleasure vessels.

For that reason some people prefer to use the simpler definition of a superyacht being any privately owned vessel with an LOA of 100ft or more. Even then some would argue that a true superyacht should be a custom built yacht of at least 35m or 120ft.

Such is the inflationary pressure on yacht sizes and terminology that the term superyacht itself has begun to lose currency among the yachting elite. Owners of craft over 50m now use the term megayacht to categorise their larger vessels, while the lesser-spotted gigayacht is reserved for yachts over 100m.

Fewer than 100 gigayachts have been built to date, making this the rarest of rare breeds. That said with the world’s largest yacht now measuring over 183m, it’s surely only a matter of time before the 200m mark will be broken and yet another term will be needed. Got any suggestions?

Boat vs. Ship vs Yacht: What’s the Difference?

Language is a tricky thing, and picking out the differences between similar terms can be confusing. This is especially true when some of the definitions overlap. This is the case with the case of boat vs. ship vs. yacht . What’s the difference? We know in our gut that there are differences between these three seafaring vessels, but unless you’re a harbor master do you really know what counts as what?

Let’s get into some definitions, and we’re going to start with the easiest to explain: What is a yacht? What is a ship? And what is a boat?

Yacht vs. Ship vs. Boat

What is a yacht.

A yacht, I think everyone would agree, is fancier than a ship or a boat. “Yacht” infers some amount of luxury , and definitely recreation. There’s also something to be said about size. A yacht tends to be anywhere between 35 feet up to 160 feet. And some yachts, known as superyachts, go even beyond that. (Jeff Bezos just built a 417 foot yacht, but that’s really breaking yacht records.)

Because of the size, yachts tend to operate in larger bodies of water–generally the ocean. Yachts are able to handle rougher ocean waves, and they are also equipped with more advanced navigation and guidance instruments than smaller boats. Likewise, a yacht tends to have a full crew to help with the navigation, engineering, repairs, as well as having stewards that serve the yacht’s guests. This can be anywhere from a crew of four or five up to a crew of a few dozen on large yachts. 

One interesting thing to note is that outside of the United States, a yacht refers to a sailboat , and a motorized yacht is called a “motor yacht”. 

So, is a yacht a boat? Yes, technically a yacht is a boat. But a yacht is a very specific kind of boat.

What is a Ship?

The term ship is most commonly associated with a very large boat, and something that is not as fancy as a yacht (one exception is that cruise ships can still be very fancy, but are referred to as ships because of their size and power.)

Ships are generally so large that they would never be found in a lake, with some exceptions for the Great Lakes, and are made for navigating the high seas of the open ocean. An ship can refer to a cruise ship, a naval ship, a tanker, a container ship, and many other commercial vessels.

Ships tend to have advanced navigation and technology, but much more advanced than that of a yacht due to the size, the speed, and the routes that a ship will take. They are meant to be traversing the open ocean for very long periods of time, from one continent to the next, while a yacht may only rarely set across the ocean and most often stays somewhat near land. 

A ship will also have a much larger crew than a yacht or a boat. Ships are typically so large that they need not only one trained navigator but a set of navigators, plus an entire engineering team, and includes many more positions. 

Finally, a ship is meant to carry things. This may be passengers, yes (in reference to cruise ships and some navy ships) but most ships are for carrying cargo–or even carrying equipment to do work on other ships including repair work or refueling. 

What is a Boat?

Well, a boat is harder to define, because a yacht is technically a boat, and a ship is technically a boat. But when people refer to boats, they are almost always referring to something smaller than either a yacht or a ship. Boats may be motorized, like a speed boat, or they may sail, or they may be man-powered, like a rowboat or a kayak. Really, anything up to and including a liferaft, can be called a boat.

(As a side note that will just muddy the waters even further, submarine captains are adamant that their subs are boats. They are not ships.)

So, Boat vs. Ship Vs. Yacht?

Ultimately it comes down to this: all three of them are boats, but yachts are fancier, larger, and used for recreation, and ships are even larger, used commercially or by the navy, and are meant to cross oceans. The dividing line is sometimes thin, but generally speaking, when it comes to boats vs. ships.vs. yachts you can go by the adage “ I know it when I see it .”

Yacht : modern meaning of the term and types of boats

• Luca D'Ambrosio
• February 25, 2023

The etymology of the term yacht comes from the Dutch word ‘jacht’, which was used in the past to define the fast sailing vessels used to hunt down pirates along the coasts of northern Europe.

Today, the term ‘yacht’ is used to describe all recreational vessels, whether sailing or motor-powered, with at least one cabin that allows the crew to sleep on board.

There is no established definition for the length of this family of boats, but common usage tends to define a yacht as a vessel longer than 33 feet, or about 10 meters.

As mentioned above, a yacht may be equipped with sailing, motor or mixed propulsion. It can have more than one hull, and if it exceeds 25 meters it also deserves the definition of superyacht . When a yacht is over 50 meters it is called a megayacht and, more and more frequently, when it exceeds 100 meters it becomes a gigayacht.

A yacht normally flies a flag that corresponds to the country where the vessel is registered, not least because, if it does not, it may be captured and taken to the nearest port for ‘flag survey’. As far as international maritime law is concerned, the yacht is considered in all respects to be the territory of the country of the flag it flies, to whose sovereignty the crew is subject.

A yacht flying the flag of a country, unless there is well-founded suspicion of illegal activity, can only be stopped for inspection by the military vessels of that country. When a yacht enters the territorial waters of a country other than that of its flag, it is obliged to fly a courtesy flag.

This is tantamount to a declaration of submission to the navigational laws of the country in which it is sailing.

Sailing and motor-powered yachts

The first major distinction is between sailing yachts and motoryachts. The current worldwide spread of these two families has shifted decisively towards motor yachts, which make up about 75% of the total sailing fleet.

Progress and design have produced many different categories of motor yachts, so let’s discover them together.

Motoryachts

Seen from the stern, a flybridge yacht is often equipped with a “beach club”, a platform that facilitates access to the sea and on which water toys are placed or simply used for diving. A staircase, or even two symmetrical staircases, leads from this platform to the main deck. Sometimes there is a “garage” between these two staircases to house the engine room, a tender and other on-board equipment.

The main deck is characterized by the presence of a helm station, inside of which a large open-space salon houses settees and a galley. The helm station often leads below deck, also known as the lower deck, where the sleeping quarters, or cabins, are normally located.

The foredeck often has a large sundeck bordered by a “bowplate” for hauling anchor. The bow is often “fenced in” by the handrails, which are vital grips for safety at sea.

Let’s get to why a yacht is called a flybridge. The flybridge is an upper deck, open 360 degrees and often covered by a hard-top, a roof usually made of fibreglass. The flybridge usually has an additional helm station to steer from a more panoramic position. An additional galley is often located on the flybridge, as well as additional lounge seating and sun decks.

Open Yachts

An open yacht has no flybridge and its main deck is commonly all open. The helm station can frequently be sheltered by a T-Top. Below deck, depending on the length of the yacht, there are living spaces for the crew which may include dinette, cabins and facilities. Open yachts can be walk-around, i.e. with the possibility for passengers of walking freely around the perimeter of the boat, or they can have an enclosed bow and thus have a raised deck.

A coupe yacht is a yacht without a flybridge, characterized by a sporty design, with the main deck open aft. Very often it has a sunroof and is always equipped with side-decks connecting the stern to the bow. It is a vessel that, depending on its size, is suitable for medium to long-distance cruising.

This is an important type of yacht, which has its origins on the American East Coast where it was used to catch lobsters. It has a romantic, sometimes vintage aesthetic, and is endowed with sinuous lines that, for some, are evocative of the 1950s. Very suitable for cruising and conviviality, thanks also to a large sofa in the cockpit, the lobster is an iconic boat that offers plenty of comfort and space below deck for at least one cabin and one head.

The trawler is essentially a yacht for owners who want to spend a lot of time on board. This is why interior volumes are maximized and the upper deck is always present. Also part of the trawler family are the famous Menorcan boats, inspired by the llaüts of the Menorca island..

Increasingly popular among motor yachts, too, is the multihull, due to its inherent features of stability and capacity. In most cases it is a catamaran designed for long stays at sea.

Sailing yacht

Sailing yachts are vessels where propulsion should mainly rely on the power transmitted by the wind. In the past, sailing yacht engines were low-powered and mainly used for entering and leaving ports, but today, for obvious reasons of practicality and ease of use, they have enough power to make the sailing yacht cruise at a speed at least equal to its theoretical hull speed. This means that sailing yachts can be used efficiently even in the total absence of wind.

A sailing yacht can be rigged in many different ways, these being the most common in modern times:

Sloop : this is the most common rigging on modern boats, characterized by the presence of a single mast with a mainsail and a jib or genoa. Sloop rigging has become popular over the years because it is the easiest to handle with a small crew and also offers the best ease of use/sailing performance ratio.

Cutter : Widely used for long distance sailing, it is characterized by the presence of a mainsail and two jibs rigged on a single mast. Normally the two jibs are a genoa and foresail that are used individually, depending on the weather conditions.

Ketch : this is the most commonly used rig on two-masted sailing yachts, with a mainmast, rigged with a mainsail and genoa, and a mizzenmast, forward of the rudder shaft, rigged with a single mainsail. The splitting of the sails makes this type of yacht suitable for sailing in bad weather.

Yawl : exactly the same as a ketch but with the mizzen mast located aft of the rudder shaft.

Sailing yachts can be monohulls or multihulls, i.e. catamarans or trimarans, but in all cases they can be divided into these categories:

Easy to handle and with plenty of space above and below deck, this type of yacht is normally characterized by an unbalanced length/width ratio favouring the latter, a small sail area and more powerful than average engines.

The interiors are fully equipped and sophisticated, with each cabin often having its own en-suite head.

The deck plan and sailing equipment are simplified, often electrified and minimal.

Cruiser-Racer

This yacht, while still featuring a luxurious and complete interior, also has all the equipment needed for sail fine-tuning and a generous sail area.

This is a category where special attention is paid to both the overall weight of the boat and the hull shape.

The hull lines are in fact designed to enhance performance and, inevitably, this results in a slightly smaller interior than that of pure cruising yachts of the same length.

Racer-Cruiser

The owner who buys this type of yacht has already competed in club competitions and now wants to engage in higher level racing. The hulls are light and can sometimes be made of carbon, and all the sail adjustments are fine-tuned to achieve maximum performance.

The deck plan is definitely designed for crewed racing and the sail area/displacement ratio is unbalanced in favour of the former, making this yacht more difficult to handle with a smaller crew but, conversely, capable of performance similar to a pure racing yacht.

A pure racing yacht is a sailing yacht built exclusively for racing. Free from any commercial constraints, it is built according to the type of race to be competed in and, above all, the rating to be obtained. The interiors of this boat are minimal. This yacht is capable of planing and sailing upwind at very low wind angles, but is almost never used for recreational purposes.

What is a Yacht?

A yacht does not have to meet any specific requirements to be considered a yacht. For our purposes a yacht is any recreational boat of around 30 feet or more that includes at least one cabin and is used for cruising or racing. This definition is not a hard and fast rule to go by as there is no settled definition for the word at all or what specifically makes a boat into a yacht.

Because a yacht is not a specific type of easily identified vessel like a pontoon boat or a fishing boat, we’ll cover the features of what makes a yacht worthy of the name so make it easier for you to identify one in the wild.

Defining What a Yacht Is

The difficulty in defining the term “yacht” is that, unlike the specific vessels mentioned above, a yacht is more of a description than a type. Yachts can be sailboats or motorboats, center console boats, house boats or any other kind of vessel that meets the generally accepted size and feature expectations of a yacht.

The definition I gave above includes a few key points:

• A yacht is a recreational boat
• A yacht is 30 feet long or more
• A yacht has at least one cabin
• A yacht is used for cruising or racing

This description allows you to weed out some things such as:

• Boats under 30 feet which most recreational boats are
• Specific purpose boats like commercial fishing vessels, barges, tugboats
• Most pontoon boats, speed boats for racing, jon boats and recreational fishing boats

Reaching a Definition

Usually when people think of yachts they’re thinking of a medium to large vessel that is well appointed and higher end with a lot of luxury features. The word evokes a sense of value and expense. We consider a yacht to be an expensive boat.

Yachts can be very similar to a cabin cruiser or day sailing boats , but the difference seems to be in size and what may be included above and beyond a “normal” boat. For these reasons, “yacht” as a term is sometimes hard to define and definitions will not be consistent from one source to another.

Motor Yacht Vs. Sailing Yacht

The initial definition of yacht that we provided doesn’t specify if a yacht is a boat that requires wind power to move or an engine. But the fact is that a yacht can be a sailing vessel or a powered vessel and either one can still qualify as a yacht.

Motor Yacht

The power source for a motor yacht is an engine. Some yachts are hybrid vessels which can run under sail but also have a backup engine in case of emergencies or if the wind is not reliable. These are sometimes called motorsailers.

Motor yachts are considered leisure vessels more often than sailing yachts due to how they work. A motor yacht takes less skill to operate than a sailing yacht.

Sailing Yacht

Sailing yachts run strictly on wind power. Most larger sail boats with cabins could be considered yachts. Many boaters still consider a sailing yacht a boat for people who are more adventurous and a little wild as they represent that idea of cutting loose at sea.  A sailing yacht is harder to operate than a motor yacht and requires more skill.

A motor yacht is going to get you where you want to go faster than a sailing yacht. That’s not to say these aren’t fast sailing vessels as modern yachts can reach great speeds, but they are still at the mercy of the wind. For that reason you’ll often see far more motor yachts around than sailing yachts as they tend to be more convenient for most boaters.

Motor yachts have no concrete average speed thanks to numerous factors that go into what makes a yacht. The largest yacht in the world is nearly 600 feet long. Obviously a boat of this size has many variables that will affect its speed compared to a 60 foot yacht. That said, yachts of any size tend to have cruising speeds that range from 20 mph to 30 mph.

Because a sailing yacht is powered by wind only it will be slower, on average, than a motor yacht. Sailing yachts often reach speeds of just 5 mph to around 10 mph. The size and construction of the vessel, its weight, and the skill of the captain can all affect these numbers.

A motor yacht has to make space for an engine room, which can get quite huge especially on large yachts. Space is also needed for fuel tanks. On some mega yachts they have fuel tanks that can hold over a million liters of fuel, which is absolutely staggering and requires a large portion of the vessel.

Motor yachts are more likely to devote space to luxury amenities like hot tubs or even swimming pools. The largest motor yachts have multiple luxury cabins, helipads, tenders, gyms and more. Some motor yachts can have up to 8 decks. You can expect a motor yacht at 150 feet to have around 50% or more space available than the exact same length in a sailing yacht. 

Sailing yachts can be designed smaller than motor yachts because they don’t need engine or fuel space. So a smaller sailing yacht can hold as many passengers as a larger motor yacht without sacrificing comfort or luxury. A sailing yacht is going to have a smaller and probably narrower structure than a motor yacht.

Sailing yachts often offer comfortable cabins but usually have few hotel-like luxuries on board.  A sailing yacht needs a lower profile to function properly. They will have fewer decks as well.

Motor yachts lend themselves more towards really having fun at sea. These are true recreational vessels. This is owing to the fact motor yachts are more likely to have tender garages and include jet skis and other equipment for getting out and having fun. 

Motor yachts also tend to be the ones that are more outfitted like small resorts. You can find dance floors, bars, swimming pools, jacuzzi tubs, gyms and more on some big luxury yachts. At some point they really start to look like small cruise ships. With the extra decks and of course because they don’t have masts in the way, there’s a lot more space for this kind of thing. 

Modern sailing yachts have been designed with more luxury features than older models and it’s not unheard of to find a jacuzzi on a sailing yacht or even a cinema on some, but it’s still a rarity when compared to motor yachts.

Sailing yachts can be used for some more limited type fun at sea – lots of snorkeling, swimming, fishing and so on, just not to the extreme that a motor yacht will do. A lot of the appeal of a sailing yacht is the fact that it’s for sailing, so the act of sailing itself is the draw. Usually people who own and operate sailing yachts want to engage in the activity of sailing, rather than the extra things you might enjoy on a motor yacht.

Cost of Motor Yachts vs Sailing Yachts

Motor yachts are more expensive than sailing yachts. The initial cost can vary widely but it’s the long term costs that nail you. Fuel and maintenance costs over time for a motor yacht will always keep raising the price. The largest motor yachts may cost millions of dollars to buy outright and also have yearly operating costs in the hundreds of thousands or even millions if they are fully crewed. The highest priced yacht in the world has a $1.5 billion price tag.

A sailing yacht continues to coast along at a much lower cost in terms of necessary maintenance. After all, you never need to refuel your sailing yacht. Some smaller yachts may cost under $30,000. 

Yacht Classifications

Yachts are often classified by size. As we defined early, any vessel over 30 feet can potentially be a yacht. But if you are talking about a vessel that is over 400 feet in length, it’s not an accurate picture to use the same term. 

We often classify yachts using common size or metric prefixes. You may have heard the terms “superyacht” and “megayacht.” These are ways of attempting to differentiate between the sizes of yachts because some of these vessels can get massive. The world’s largest yacht, the Azzam, is about 600 feet long. 

Large Yacht

According to the Commercial Yacht Code, a large yacht is any yacht that has reached 79 feet or more. At this size the boat needs to have an actual crew to keep it running. Anything under 79 feet would just be a standard yacht.

Super Yacht

To qualify as a super yacht, a vessel has to be at least 131 feet in length. Obviously this size means it needs a fairly extensive crew and, if it’s not a commercial vessel, it’s probably owned by someone extremely wealthy in order to maintain it. 

The term mega yacht is a bit sketchy which is no surprise given how there’s only a loose definition for the word “yacht” in the first place. Mega yacht and superyacht are often used synonymously. However, for some people, the term mega yacht can only be applied when the vessel reaches at least 200 feet. This doesn’t seem to be a definite rule though so if you hear the term it’s still best to look at the specs of the boat to see what’s being referred to. 

You hear this term a lot less frequently but it’s been tossed around to account for those yachts that would even leave a mega yacht in the dust. After all, if a super yacht is 131 feet and a mega yacht is 200 feet then a yacht like Azzam, at 600 feet, should probably be known by a different term since it’s so much bigger.

Giga yacht is sometimes used to represent these largest yachts. But again, this is an informal label for such a large boat and there are no hard and fast rules about what size a boat has to be in order to be called a giga yacht. In general it just means the biggest of the big. 

Racing Yachts

If the point of the yacht is specifically to be involved in racing, then it will likely be stripped down of many of the more luxurious but unnecessary amenities seen in recreational and cruising yachts. Usually a racing yacht has less space for relaxing or sleeping, for instance, but there are definitely yachts being built that offer a lot of nice features while still being designed to race.

The Bottom Line

There are no distinct rules for the size of a yacht or what it can even do. A yacht can operate under motor power or under sailing and you can use it to race, to just have fun, or for cruising. They can range in size from just 30 feet all the way up to the massive 600 foot Azzam. 

A yacht is a vessel that is fairly luxurious and used recreationally for a variety of purposes. A luxury yacht may be chartered for business or events and come with a full crew while smaller motor powered yachts and sailing yachts tend to be used for pleasure cruising.

Yacht classification definitions

The merchant shipping sector is ruled by safety regulations developed since the beginning of the 20th century, and is familiar with international conventions such as SOLAS, MARPOL and Load Lines. But the application of common safety requirements to pleasure vessels is something relatively new – a continuous work in progress – and is very much dependant on the service and the flag of the yacht.

Defining the problems

Definitions do not help. How often have we read of large yachts, superyachts, megayachts, gigayachts or other bombastic adjectives? How many times have we mentioned MCA, RINA, and Lloyd’s, without having a clear idea of who’s doing what?

A good starting point for understanding the subject is to clarify the main definitions and the roles of the main players:

Large yacht

A large yacht is a pleasure vessel with a load line length equal to or over 24m. Almost all the flag administrations have adopted safety codes dedicated to large yachts and this is, therefore, the only definition having a universal meaning in the international regulatory framework of yachts.

Commercial yacht

A motor or sailing vessel in commercial use (i.e. charter) for sport and pleasure, carrying no cargo and not more than 12 passengers.

Private yacht

A pleasure vessel solely used for the recreational and leisure purpose of its owner and his guests.

Flag administration

The government of the state whose flag the yacht is entitled to fly . This administration sets the safety regulations, manning requirements and fiscal aspects relevant to the yacht registration.

Different flag administrations can inspect the safety aspects of yachts with their own inspectors (see MCA for example) or delegate this activity partially or totally to other recognised bodies such as the classification societies.

The main flag authorities in the yachting industry are: The UK-MCA, Cayman Islands, Isle of Man, Malta, the Marshall Islands, Italy and Luxembourg.

Classification societies

Organisations that establish and apply technical standards in relation to the design, construction and survey of ships.

Classification rules are developed to assess the structural strength and integrity of the essential parts of the hull, the reliability and function of the propulsion, steering systems, power generation and all the other features installed on board which contribute to guarantee the main essential services.

In addition to this ‘third party check’ function, class societies carry out statutory duties on behalf of the major flag administrations in accordance with specific delegation agreements signed with each government.

The main class societies involved in yachting are: American Bureau of Shipping, Bureau Veritas, Det Norske Veritas, Germanischer Lloyd, Lloyd’s Register, and RINA.

Large yachts: Applicable rules and certificates

Private yachts

The mandatory requirements for these boats are very light. For the majority of flag states, a registration survey and a tonnage measurement, carried out by an authorised surveyor, are sufficient.

The only mandatory international conventions are those relevant to the marine environment: MARPOL and the Anti-Fouling System Convention.

The International Convention for the Prevention of Pollution from Ships (MARPOL) is intended to eliminate the intentional pollution and to minimise the accidental pollution of the marine environment caused by harmful substances.

The Anti-Fouling System Convention’s purpose is to eliminate the presence of harmful substances for the marine environment contained in anti-fouling paints applied to ships.

Classification

While classification is not mandatory, building and maintaining a private yacht in class is the only evidence that the boat has been designed, constructed and operated in compliance with appropriate technical standards. It is therefore highly desirable, especially in relation to insurance and re-sale purposes.

Commercial yachts

All flag administrations require commercial yachts to be certified in accordance with a specific large yacht safety code.

The most popular of these safety codes, and the first that was developed, is the MCA Large Commercial Yacht Code (LY2) published in 2004. It replaced the Code of Practice for the Safety of Large Commercial Sailing and Motor Vessels (LY1) published in 1997.

LY2 is applied by the Red Ensign Group Flags (UK, Cayman Islands, Isle of Man, Bermuda, Gibraltar, British Virgin Islands, etc.) and is recognised as a reference standard for all the yachting industry.

Other flags have developed similar codes. Luxembourg, Italy, Marshall Islands, Malta, Belize and The Netherlands are some examples.

While introducing a stricter set of rules and regulations compared to private yachts, commercial registration offers yacht owners the possibility of making a profit from the chartering activity of their boats, and allows them to take advantage of all the other benefits of a commercial operation (in particular VAT exemption on the purchase, sale, bunkering, provisions, dry-docking, and others).

Mandatory certificates

The number and type of the mandatory certificates depends on the size of the vessel; the following is an indicative list:

• International Tonnage Certificate : A measurement of the internal volumes of the yacht expressed in gross tons (GT). This measurement should not be confused with displacement tonnage, which quantifies the weight of a vessel.
• Large Yacht Code Certificate : Covers life-saving appliances, fire protection and means of escape, navigational and signalling equipment, intact and damaged stability, manning and crew accommodation.
• Class Certificate : This mainly deals with the yacht’s hull, machinery, electrical equipment and outfitting.
• International Load Line Certificate : This certifies the weather-tightness of the yacht.
• Safety Radio Certificate : This is applicable if gross tonnage exceeds 300GT This concerns the radio communication and distress installations.
• MARPOL Annex I Certificate : This is applicable if gross tonnage exceeds 400GT This deals with the disposal of oil and bilge water from machinery spaces.
• MARPOL Annex IV Certificate : This is applicable if gross tonnage exceeds 400 or the yacht is certified to carry over 15 persons. This deals with the disposal of sewage from ships.
• MARPOL Annex V : This is applicable to all ships. It covers the disposal of rubbish.
• MARPOL Annex VI : This is applicable if gross tonnage exceeds 400GT as well as to all main and auxiliary engines with a power exceeding 130kW. It concerns the emissions from main and auxiliary engines (NOx and SOx).
• Safety Construction and Safety Equipment : These are additional prescriptions on machinery, electrical parts, life-saving and navigational equipment for yachts with a gross tonnage above 500GT.
• International Safety Management Certificate : This is only applicable to yachts having a gross tonnage greater than 500GT. A certified management company is requested to carry out this service, preparing operational manuals, procedures for drills, and taking care of the maintenance of the yacht and its installations.
• International Ship and Port Security Certificate : This is only applicable to yachts having a gross tonnage greater than 500GT and deals with the anti-piracy certification. A certified management company is requested to provide the ashore assistance and establish on-board procedures and operational manuals.

The GT Factor

The gross tonnage value (GT) is a key issue, not only as a reference for the registration fees applied by the different flag administrations, but also because it determines whether an international convention, rather than a particular safety standard, applies to a yacht.

The table below summarises how the conventions and relevant certificates come into force depending on the gross tonnage of the yacht. In particular, the following values may have a critical impact:

300GT: In many codes, when you reach this value the yacht must be certified in unrestricted service (stricter requirements regarding stability, load line and life-saving appliances).

400GT: This is the threshold for almost all the environmental conventions such as MARPOL and Anti-fouling System.

500GT: This is the threshold for the application of the SOLAS Convention, meaning stricter requirements on machinery, safety systems, materials of construction, fire protection, life-saving appliances and navigational equipment. Furthermore an external certified management company is requested for the ISM and ISPS certifications.

The tonnage issue could also arise on existing yachts when undertaking major refits or modifications, in that any change to the internal volumes of the boat – such as adding enclosed deckhouses or superstructures, or modifying the hull transom or bow – will modify the tonnage value with the risk of subjecting the yacht to stricter mandatory rules.

UPDATE: Since this article was originally published, LY2 has been superseded by Large Commercial Yacht Code Revision 3 (LY3) .

• 7 Differences Between a Ship and a Boat

Although most people know the difference between a ship and a boat, some can get confused between the two.

While talking about the difference between a ship and a boat, the first thing that comes to mind is their sizes. Usually, people consider ships to be massive whereas boats are smaller.

However, there are other aspects too, apart from size, which are discussed in this article.

1.  Size of Ship and Boat

The most important aspect while stating the difference between a ship and a boat is the size. It is said that the best way to differentiate between a ship and a boat is to remember that “A ship can carry a boat, but a boat cannot carry a ship.”

Technically speaking, a mode of water transport that weighs at least 500 tonnes or above is categorised as a ship. In comparison, boats are small in their structural size and displacement.

2. Operational Areas

Ships ply in deep waters, oceans and high seas. They are of various types like cruise vessels , naval ships, tankers , container ships , RoRo ships , and offshore vessels . They are mainly built for cargo/ passenger transportation across oceans.

Boats, in contrast, operate in restricted waters, near the coast and include ferrying and towing vessels, sail vessels, paddle vessels, kayaks , canoes , patrolling boats etc.

 3 . Navigation and Technology

Boats are simple vessels with less complicated equipment, systems and operational maintenance requirements.  Since ships are huge and carry large volumes of cargo over large distances, they feature advanced engineering, heavy machinery, and sophisticated navigational systems .

4. Crew Size

This is one of the major differences between a ship and a boat.

Ships have a large crew which consists of the Captain who commands the vessel, Second and Third Officers, Engineers, Cooks etc.

On the other hand, a smaller boat does not need many people.

5. Cargo Capacity

A boat is hardly used for carrying cargo. It is mostly used for recreational purposes like boating, fishing or ferrying people across short distances. Ships are built to be seaworthy since they carry thousands of tonnes across different ends of the planet.

Ships can also accommodate passengers or boats, whereas boat is a generic term used for a variety of watercraft.

6. Construction and Design

When it comes to construction and design, ships are complicated structures with various onboard machinery systems and equipment to ensure they are safe and stable to cross the rough seas.

A boat has a simple design and almost no machinery, though sophisticated ones have navigation systems, however they do not take up much space.

7. Propulsion

A boat can be powered by sails, motor, or human force, whereas a ship has dedicated engines. (Ships can also be propelled by sails or other advanced propulsion technologies)

Even though all vessels on the high seas are referred to as ships, submersible vessels are categorically termed as ‘boats.’

This is mainly because earlier, submersible vessels could be hoisted on ships till they were used in naval operations.

However, while talking about differences between a ship and a boat, only the vessels floating on the water surface are taken into consideration.

The use of the term ‘ship’ or ‘boat’ also depends on the region it is being used in. People often refer to a medium-sized fishing vessel as a boat, a medium-sized ferry or a recreational boat as a ship. As can be seen, people tend to generalise a vessel based on its size.

However, it is to be noted that the difference between a ship and a boat depends on many factors as discussed above.

Please i am a National Diploma student of Maritime Academy of Nigeria Oron studying nautical science, i want to know more about the course

Hi.thank its so good and sufficient

As a profesional mariner of over 25 years I would like to “weigh in” on this subject. What I will say is not about the currently accepted distinction between ship and boats, but rather historical. When ships (powered by sails) began to start losing trade to vessels powered by engines (boats) they as an industry attempted to associate these vessels with unplesant attributes like noise, soot, vibration, and in some cases slower speed. The sailoing industry (both cargo and passanger) would say that you could SAIL on a quiet, clean, calm, fast ship or go one of those dirty loud vibrating slow BOATS with an engine. The concept a ship being superior and a boat being inferior was sucessfully instituted. The engine powered vessels simply side stepped the ridicule bestowed on the term “boat” and made bigger, faster, clean, quiet vessels and took the market from the sail powered vessels along with the defination of SHIP for themselves. i wont step into the curret debate of what constitutes a boat or a ship but the origins of the debate stem from new technology (steam engines) fighting over market share.

A large freighter (1000′ x 85′, think of the Edmund Fitzgerald) hauling iron ore on the great lakes is referred to by her crew and company as a boat, never as a ship!

“Boats in contrast, are operable in smaller/ restricted water areas and include ferrying and towing vessels, sail vessels, paddle vessels, kayaks, canoe, patrolling vessels etc. Boats are mainly used for smaller purposes and mainly ply in areas near to the coast.” “Technologically, boats are simple vessels with less complicated equipment, systems and operational maintenance requirements.”

Correct me if I am wrong but, isn’t a submarine classed as a boat? That kind of contradicts what you have stated above.

comment:the any where abroad/indian officers you can any time call me on 30 year’s on merchant officers

You can put a boat on a ship but not visa versa eg life boats…

What is the difference between a boat and a ship?

1. The boat leans to the right when turning right

2. The ship leans to the left when turning right.

This is what I have been told by a old (90 Year old boat capt)

Great reply’s. some years ago while on the QE 2 a passenger asked one of the officers when does this boat dock? The young officer replied. “Madam, this is a Ship not a boat, a boat is those you get into when this ship is sinking!

Hello. May I please ask for some assistance from the forum?

I am writing a blog/journal on the differences between ships and yachts. What has prompted this conversation is the plethora of ‘superyachts’ now plying the international oceans and performing well on deep water passages.

Surely some of these can come under the category of ‘ship’, and not yacht, since many are being built on a larger scale than anything we’ve seen in past years. My understanding of the determination of a ‘ship’ is : Length, Tonnage, Draft and Displacement.

I have read your forum discussion regarding use, but I am still unclear as to where the line is drawn for this category. Many of the ‘superyachts’ carry cars, helicopters, pools, and require very advanced equipment, captain and crew. Perhaps we will soon see this as a real conversation in the industry.

Appreciatively, Rosanne Allen-Hewlett For ‘The LUXE Report’ ( Sailor, racer of only boats and yachts )

I was told that the difference between a ship and a boat is that a ship has a funnel and a boat doesn’t, no matter it’s size….

David Musselwhwite’s comment is the best way to determine a boat of a ship. This holds true for submarines (boats). If it leans into the turn, it is a boat. If it leans out on a turn, it is a ship.

In response to comments about the Edmund Fitzgerald, when you spend your life on one you can call it whatever you want. I am sure they all knew it was a ship, I served 20 years in the Navy and always said I was heading back to the boat even though I knew it was a ship.

While in Boot camp in 1964, US Coast Guard, we were told that a ship is 95 feet or longer and a boat is 94 feet and under. That makes it pretty simple.

With over 30 years in the marine industry including working at sea, ship building and ship repair, I would offer my comments.

Yes all above is true. My understanding is that the bottom line is ” a Ship carries boats ie Lifeboats”. If it doesn’t have a proper lifeboat, it is not a ship.

The best a boat has is dinghies or liferafts etc. Consequently a submarine does NOT carry life boats. There are many broader requirements Size and the ability to navigate very heavy seas, such as those whipped up by a tropical Revolving storm (TRS). It must be designed to travel in the open sea in all weather conditions and have lifeboats that can do the same. They carry cargo or passengers and have a substantial crew to operate it including engineers.

As far as the Edmund Fitzgerald is concerned, these vessels are an enigma. They were large and qualify in most areas, but – was it capable of going to sea and did it have sea-going lifeboats? Ironically it suffered probably as bad a storm as it would have done at sea. The problem is that in fresh water the waters are more treacherous than salt water as they rise up far more quickly.

But then again it sank meaning that it couldn’t handle it. Yes it was a large vessel but was it a Ship – ?

What is difference among?

Marine Boat Marine Ship Marine Craft Ship Boat

What is difference between Marina and Marine?

Being the son of a WW II submariner. My dad cruised the Atlantic of the east coast of US and in many conversations about the war he always called his boat a boat never a ship.Thats it!!

The simplest and most accurate definition I stay with is that a ship can carry a boat but a boat cannot carry a ship . SIZE MATTERS !

Captain chalga: try to form a coherent sentence.

I asked a friend of mine, “What is the difference between a boat and a ship?” He said, “About 100 feet . . .”

Thank you for the information. My husband won this discussion. God Bless all who are bravely floating on/in one. I am terrified of the ocean or even a small lake. You have my utmost respect for your sacrifice. I love seafood but would never know the pleasure of eating it without you brave souls. Thank you.

As a proud Submariner I have to disagree and will always say that I serve on a boat.

There is the Boat of Millions of years,which is a very advanced spacecraft able to.travel the millions of light years betwen Galaxies.

And you have vessels such as the Motor Vessel Arlene out of Port Arthur.

I was once told that a ship had multiple decks and a boat had only one.

When I queried sailing yachts that had berths under part of the deck, it was modified to the deck on a yacht is as much structural as deck, but if a vessel has 2 or more non structural “floors” it is a ship.

Then I mentioned tug boats and fishing boats and it all got confused.

It’s a bit like the difference between horse and pony. Despite every one saying it’s size, the falabella is a horse and polo ponies are ponies.

A naval architect (constructors) view is that to be a ‘ship’ a vessel must have at least one continuous internal deck running the length of the vessel. Large Submarines may have complete decks forward however, going aft, it is normal to have to descend a ladder onto a lower ‘engine room’ deck-level or platform. Some large freighters have a similar construction with internal split deck levels and that is why they are correctly known as boats, although in some cases the term ‘ship’ feels more appropriate because of their large displacement. The argument regarding leaning into or out of a turn is an interesting idea, however this may have more to do with hull and propulsion characteristics than vessel construction. In reality, as with most nautical expressions, whatever feels best to use is probably best and relying on the opinion of a sailor, with regards to an explanation of nautical expressions, puts you at the mercy of a sharp sense of humour.

It might be worth mentioning that some might refer to a ship as “boat” as a diminutive term of endearment, similar to the personification of a car or a pet by assigning the human pronouns to them.

I was once told a SHIP sails the oceans, a BOAT sails on rivers and lakes.

IT SEEMS WE HAVE VERY KNOWLEDGEABLE SEA MEN IN THE HOUSE . BUT I AGREE TOTALLY WITH JEREMY MEYER

It’s always been my info is that a boat can be up to 197’ whereas a ship is over that length. As with anything, I’m sure there are exceptions.

some of the people got it spot on. Tilt away from direction of turn = ship. Tilt towards the direction of turn = boat.

There are two points on every vessel. Center of buoyancy and center of gravity. A ship’s center of gravity is above its center of buoyancy. A boat’s center of gravity is below its center of gravity.

Anyone can answer me why we only know the bareboat charter for any size of the ship? It never mentions bareship charter?

“some of the people got it spot on. Tilt away from direction of turn = ship. Tilt towards the direction of turn = boat. There are two points on every vessel. Center of buoyancy and center of gravity. A ship’s center of gravity is above its center of buoyancy. A boat’s center of gravity is below its center of gravity.”

Except a kayak (or canoe) is like a ship – cg is above cb. If you get a ruddered kayak up to speed and hit the rudder hard it will heel outward like a ship. Since the paddler can easily influence heel, if you want to make a hard turn you heel the ‘boat” outward (to lessen the ends in the water) and sweep stroke on the outward side to spin the “boat”. Is a kayak then a “ship”? Hardly. This is exactly the problem with trying to make one pithy statement to define a ship or boat. It is far more complex than that.

I completely agree with you that the difference between a ship and a boat is the size. One of my friends have a boat, she bought it from Boat Lagoon Yachting. Thanks for sharing!

If you can haul it on the back of truck (even trailered), it’s likely a boat…but if the anchor weighs in like a truck it’s definitely a ship. Obviously, some subs are one or the other regardless of whether you can stuff a (non-inflatable) life boat inside. [Army logic from qualified ex-boat commander, combat support boats, bridge section, Corps of Engineers.]

I grew up near the Welland Canal, and it’s true: vessels which plied the Great Lakes were called “lake boats”, or more commonly, “Lakers”. Oceangoing vessels a were always and reflexively called “ships”..

I am wondering if the naval architect”s comment about internal decks makes the difference, as even a non-engineer can see that a deck extending stem to stern would provide more stability to a vessel’s structure.

The lake boats are always longer than the ocean-going ships, so it’s not size.And we occasionally get a visit from “tall ships”, which are oceangoing sailing vessels, but relatively short.

That’s really informative post. I appreciate your skills, Thanks for sharing.

I will take a shot at this. The word marine is redundant before ship and boat. The word “marine” relates to the sea and one of the conditions of being a ship is that it is ocean going. This does leave the possibility of not being a river boat but a marine boat. I would use the expression sea-going boat.

Marine craft is a useful expression when there is a need to make it cleat that you are not referring an aircraft, space craft etc.

On a general note there are no absolute rules or definition. All we can do is give examples of how the words are used. Companies, governments, navies and anyone else are free to make gheir own definitions but nobody else is bound by them.

I served on the U.S.S. CG-19 ‘THE DZLE & U.S.S. CV-63 KITTY HAWK FOR THE US NAVY in the 80’s. So what about the placement of the helm being center of Bridge on a ship & on starboard side usually on a boat?

With many years of sailing lakes to blue water sailing and large power yachts I can offer this for abot of levity. Afterall,the SeaView had the ‘Flying Sub” flown or driven undersea,on the surface and flown by Captain,Admirals and sadly Polititians and insane quasi research criminals. The Flying Sub also had an inflatable Zodiac,so both could be considered Life saving vessels. Plus,it was really cool!

Can be as difficult as we want. My training was as a NCO (enlisted man in the USN. As others have stated, A ship will lean away from its turn. A boat will lean into the turn. This is naturally due to there the center line of gravity is located. Cargo ships mass above that line. A boat can be loaded onto a ship (lifeboats). Regarding Submarines, they are affectionately referee to , by the crew, as boats and that goes back to WWI /II, the ELB. Electric Boat Div of General Dynamics, located Groton Connecticut .

This design is wicked! You obviously know how to keep a reader entertained. Between your wit and your videos, I was almost moved to start my own blog (well, almost…HaHa!) Fantastic job. I really loved what you had to say, and more than that, how you presented it. Too cool!

More importantly… are they all “She’s” ?

I’ve been wondering about this since I was younger and saw The Hunt for Red October. The COB (Chief of the Boat) was an interesting character, and I wondered by a Sub Chief was called Chief of the Boat, if a sub was a naval ship. Some very interesting and fascinating answers in here! I like the one about how a ship turns, leaning into it or not. That makes sense to me. As for the tiny kayak/canoe exceptions to this, I’d guess that if a human weighs more than the ‘vessel’ and can manipulate it’s attributes of buoyancy or center of gravity whichever, with their own body, then it doesn’t really count as either a boat or a ship. It really has no deck, nor propulsion other than human muscle, no anchor, etc. I don’t see it as much more than a modern design for what used to be termed a ‘raft.’ But I am just spit-balling here, don’t blast me! lol

That’s really nice post. I appreciate your skills. Thanks for sharing.

All the information that you shared with us is very useful for us. Thank you for sharing with us.

“Boat” vs. “Ship”: Chart A Course To Understand The Difference

• Boat Vs. Ship
• Yacht Vs. Boat

Ahoy, me hearties! A true seadog worth their salt would never let aboard a landlubber who calls their ship a boat . That kind of mixup is the talk that gets you walking the plank!

In this article, we’ll sail the seven seas of nautical knowledge to define the difference between the words ship and boat , explain what they refer to in technical and casual use, provide examples of different kinds of both ships and boats , and we’ll even clear up the meaning of the word yacht .

🚢 Quick summary

In casual use, the word boat is often used to refer to any watergoing vessel, regardless of its size or how it’s powered. However, large oceanfaring watercraft—those that use multiple sails or engines—are more properly called ships . In contrast, the word ship isn’t commonly applied to smaller craft. The word yacht is typically used to refer to any larger noncommercial vessel—one used for sailing or other recreation, as opposed to business.

What’s the difference between a boat and a ship ?

By definition, a boat is “a vessel for transport by water,” “a small ship,” or “a vessel of any size built for navigation of rivers or inland bodies of water.” In casual use, the word boat is used to refer to any vehicle used to travel on the water—anything from a canoe to an ocean liner.

In this kind of casual and general usage, the word boat is often used to refer to watercraft of all sizes and types, as you can see in the variety of terms that include the word, such as sailboat , motorboat , fishing boat , rowboat , tugboat , paddleboat , and lifeboat .

In contrast, the word ship is typically reserved to refer to a large, ocean-faring vessel propelled by multiple sails or engines.

(Of course, the word ship is also used to refer to large, nonwater craft, such as airship and spaceship .)

In technical, nautical contexts, the word ship sometimes specifically refers to a sailing vessel that has three or more square masts. As is the case with boat , though, the word ship is applied in the name of a variety of large watercrafts, including cruise ship , cargo ship , pirate ship , battleship , longship , and steamship .

In contexts where it’s important to distinguish the difference, the distinction made between ship and boat is typically based on the size of the craft being discussed and if it is used only for ocean or sea travel. Additionally, the word boat can refer to vessels that don’t have any sails or engines, such as a kayak or a rowboat, whereas the word ship usually refers to vessels with many sails or large engines. Even in casual usage, it’s very uncommon for someone to call a small craft a ship , unless they’re doing so jokingly.

One distinction made in nautical contexts is that the word ship often refers to vessels too large to fit inside other vessels. By contrast, the word boat is often used to refer to smaller craft that can fit inside larger ones. For example, a massive cruise ship may have a large number of lifeboats inside it.

Yacht vs. boat

The word yacht typically refers to a vessel used for private, noncommercial reasons (those other than business), such as sailing or racing. As a general term, the word yacht can refer to any watercraft that isn’t intended to be used to make money, which includes anything from racing sailboats to billionaires’ floating ultra-luxury mansions.

The word yacht is not used to refer to small vessels, such as row boats or canoes. In casual usage, a yacht may be referred to with the more general terms boat or ship , but certainly not all ships and boats are yachts .

Boat vs Ship: 8 Ways to Help You Tell the Difference

Welcome to this article! At first glance, you might think that distinguishing between a boat and a ship is simple—ships are big, and boats are small, right?

Well, that may have been true in the Age of Sail, when the distinction between a sailing ship and a boat was clear. In modern times, however, the lines between these two terms have become blurred, and the simple distinction of size is no longer sufficient, leading to some confusion.

In this article, we’ll explore eight key differences that will not only help you distinguish between a boat and a ship, but also give you a deeper understanding of how these terms have evolved in today’s maritime world. Keep reading to uncover the details!

Before we learn the difference, let’s look at the definitions and origins of the two terms.

The term ship originates from the Old English word scip , which traditionally referred to larger seafaring vessels capable of undertaking long voyages to transport people or goods. Ships were historically vital for trade, warfare, and exploration.

On the other hand, boat derives from the Old Norse word bátr , which was used to describe smaller watercraft. Boats were typically employed in rivers, lakes, and coastal waters, often for fishing or short-distance travel or specific tasks.

Ability to Sail Long Distances

One of the most fundamental differences between a ship and a boat is their ability to travel long distances

Ships are typically designed to carry goods or passengers over long distances, including ocean voyages.

Examples of ships include passenger ships, oil tankers, cruise ships, aircraft carriers, and cargo ships.

They can carry large numbers of people, equipment, and goods, allowing them to travel across oceans and even between countries.

Boats, on the other hand, are generally designed for shorter distances or more specialized tasks.

Examples include yachts, jet boats, fishing boats, canoes, lifeboats and rescue boats .

They are mainly used for more straightforward journeys, such as moving between marinas, covering short distances or carrying out recreational activities close to the point of departure.

Size and Capacity

While no strict size boundaries distinguish ships from boats, in general, ships are significantly larger.

Ships often exceed 140 meters in length, with the largest container ship (MSC Irina) stretching beyond 400 meters! They typically weigh more than 10,000 tonnes and have substantial capacities for crew, cargo, and complex operations.

In contrast, boats are generally smaller. Their lengths can vary from 7 to 20 meters, depending on their type and purpose.

Unlike ships, boats are not designed to carry large amounts of cargo or passengers and have smaller structural sizes and displacements.

The distinction becomes blurred with large yachts, such as the superyacht Azzam, which measures 180 meters (590 feet) in length.

Despite their considerable accommodation space, fuel reserves, and provisions, large yachts are still classified as boats due to their primary function and design, which typically support short trips between islands.

Direction of Lean When Turning

Boats typically feature simpler designs. They are often open and lack complex structures—examples include canoes, sailboats, and fishing boats. Their center of gravity is generally below the freeboard.

Ships, on the other hand, have taller superstructures, usually consisting of multiple decks, expansive engine rooms, and large living areas. This construction places the center of gravity above the freeboard, giving ships a different stability profile.

From a naval perspective, there’s a clear and practical distinction. A ship will heel outward during a turn, while a boat will lean inward.

This difference occurs due to the way ships and boats handle turns. Ships turn with a rudder located above the keel, which causes them to lean outwards during a turn.

In contrast, small boats often rely on directional changes initiated by the propeller (such as jetboats and speedboats), making them lean inwards during a turn, with their undersides facing the water.

Purpose and Use

Boats are typically used for recreation, short-distance travel, or specialized tasks such as fishing or rescue operations.

They are often designed for brief excursions and don’t usually need to carry large amounts of supplies or equipment.

Ships, on the other hand, are built for long-duration operations and have the capability to operate independently for extended periods without needing to return to shore for resupply.

Equipped with advanced navigation systems, ships are ideal for freight transport, long-distance voyages, military operations, and various other commercial purposes, thanks to their larger carrying capacity and endurance.

Operational Areas

Another key differentiating factor is the environment in which they operate.

Ships are designed for deep-water, ocean-going voyages, and can withstand heavy sea conditions.

They are often used for international trade, long-distance travel, and military operations. Only well-equipped, large ships can navigate waters with higher sea states and rough conditions.

Boats, by contrast, are typically designed to operate in inland waters such as lakes, rivers, and coastal areas.

They are not built to handle the challenges of open oceans, where a single large wave could potentially capsize them.

So, when you see a vessel on the open ocean of the appropriate size and capacity, you can confidently call it a ship. But on inland waterways, smaller vessels are generally referred to as boats.

Evolution of technology

You might have heard the saying, “ A ship can carry a boat, but a boat cannot carry a ship. ”

For a long time, this was considered an undeniable truth—ships had the capacity to carry boats onboard, often transporting people or goods across the sea, while boats, by definition, were too small to carry ships.

However, in modern times, this saying is no longer as clear-cut. The boundaries between ships and boats have been blurred with the advancement of shipbuilding technology.

Floating docks now can carry massive ships such as warships and cruise ships. They can load, transport, and even sail with these colossal vessels onboard.

Ferries and heavy lift carriers can also transport a variety of smaller boats, cars, and even large naval destroyers.

In 2019, for example, the heavy transport vessel BOKA Vanguard carried the damaged Carnival Vista cruise ship back to port for repairs. So would you call a cruise ship a boat in this case?

Additionally, jack-up rigs and liftboats function as both ships and offshore platforms, further complicating the definitions.

These advancements in technology have caused the distinctions to evolve over time. In certain situations, a ship can carry another ship, which challenges the traditional definitions and makes the terminology dependent on the specific circumstances.

Cultural Interpretations

In cultural contexts, ships often symbolize exploration, power, and adventure. Iconic vessels like the Titanic or Columbus’s Santa María evoke deep historical and emotional connections. Ships represent monumental achievements and pivotal moments in history.

On the other hand, boats are seen as more personal and recreational. They are associated with leisure, simplicity, and intimate adventures. Boats are integral to local customs and traditions, such as the fishing boats found in coastal villages.

Linguistically, there isn’t a strict line separating the terms “ship” and “boat,” so context is crucial when using these terms.

Generally, shipowners and maritime professionals may take offense if their ship is referred to as a boat, viewing it as a sign of disrespect towards their profession and the vessel’s significance.

In maritime traditions, it’s common for sailors to affectionately refer to their ships as “boats,” similar to how one might name a personal car.

While this is acceptable within the crew, non-crew members should be cautious. For example, a new sailor referring to a warship as a “boat” might upset the captain, who may firmly correct them, saying, “It’s a ship!”

Ownership and Accessibility

Generally, acquiring a small boat or yacht is relatively straightforward and affordable for individuals. The cost ranges from approximately $50,000 to $500,000 USD, making it accessible for personal enjoyment.

Owners typically do not need to employ a large crew; they can simply bring family or friends along for recreational purposes.

In contrast, ships are usually owned by large organizations such as shipping companies or navies and come with substantial operational costs.

Individuals generally cannot purchase ships due to their complexity and expense.

Operating a ship requires a professional crew, including skilled technicians, sailors, navigators, engineers, and a commanding officer, to manage its intricate systems and ensure safe and efficient operation.

So what are Vessels?

The term “vessel” comes from the Latin word vassis, meaning “container,” originally referring to something that holds or carries.

In the maritime world, it is a broad term that applies to any watercraft navigating the seas, rivers, or lakes, regardless of size or function—ranging from small recreational boats to massive oil tankers.

“Vessel” is a universally recognized and formal term often used in legal, regulatory, and technical contexts, symbolizing the authority and structure of maritime operations.

Interestingly, maritime professionals use “vessel” for convenience to describe anything that floats on water, be it a ship, boat, or even a simple piece of driftwood.

So, when you’re uncertain whether to call something a “ship” or a “boat,” you can never go wrong by referring to it as a “vessel.”

Are Submarines Ships or Boats?

Reading this, you might wonder: submarines can float and sink, so which category do they fall into—boat or ship?

While submarine sailors often refer to submarines as “boats,” submarines are technically and normatively considered ships.

This stems from the early days when submarines were much smaller, typically around 15-20 meters in length, and could only accommodate crews of about 10 people, so the navy referred to them as ‘boats’.

Today, modern military submarines average over 100 to 150 meters long, with crews of 150 or more, making them—by any legal and operational standard—definitely ships.

By now, you should have learned how to differentiate between boats and ships based on principles, structures, uses, features, and habits.

To be honest, there isn’t a universally accepted definition for “ship” or “boat,” and classification often depends on the context of the conversation.

While the terms are usually not used strictly in everyday situations, accuracy becomes crucial in professional settings, particularly in maritime activities and communication.

More importantly, precise terminology is essential when necessary to avoid ambiguity in legal and technical environments.

Captain, 2 crew members from Mike Lynch's family yacht reportedly under investigation over sinking off Italy

By Anna Matranga

Updated on: August 28, 2024 / 10:47 AM EDT / CBS News

Rome — The engineer and a sailor from the crew of the luxury superyacht that sank off the coast of Sicily , killing British tech entrepreneur Mike Lynch and his 18-year-old daughter along with five other people, have been placed under investigation by Italian prosecutors along with the captain of the vessel, according to the Reuters and ANSA news agencies. CBS News could not immediately reach the prosecutors or lawyers for the Bayesian yacht's crew members to confirm the development, which comes about a week and a half after the vessel capsized on Aug. 19.

Engineer Tim Parker Eaton and sailor Matthew Griffiths, who was on night watch duty when the incident occurred, were reportedly placed under formal investigation for possible manslaughter and culpable shipwreck a few days after the 184-foot Bayesian yacht's captain, James Cutler, whose lawyers have confirmed that he's a subject of the probe.

After meeting with prosecutors for several days, Cutler, a 51-year-old New Zealander, has declined to answer any further questions, his lawyer said Wednesday.

"The captain exercised his right to remain silent for two fundamental reasons," attorney Giovanni Rizzuti told reporters. "First, he's very worn out. Second, we were appointed only on Monday and for a thorough and correct defense case, we need to acquire a set of data that at the moment we don't have."

Lynch and his daughter Hannah, 18, were among the passengers and one crew members who died when the superyacht sank rapidly during a violent storm in the pre-dawn hours of Aug. 19. The capsize of the high-tech vessel quickly raised questions, as another sailboat that had been anchored nearby off the coast of Palermo made it through the storm unscathed.  

Fifteen people, including Lynch's wife Angela Bacares, escaped to a life raft and were rescued by another boat that had been in the vicinity.

According to reports by Italian media, investigators are looking into whether the engineer, Eaton, might have neglected to activate security systems designed to automatically close all the hatches on the vessel, leaving the engine room to flood and possibly causing a power outage and the subsequent rapid flooding of the entire yacht.

Under Italian law, being placed under investigation does not necessarily mean formal charges will follow. 

During a press conference on Saturday, prosecutors said the investigation would require the wreck of the Bayesian to be salvaged from the seabed, where it currently sits at a depth of about 160 feet. 

Chief prosecutor Ambrogio Cartosio said his team would work to determine whether the captain, other crew members, or the yacht's manufacturers bear any responsibility for the sinking.

How safe are luxury yachts? What to know after Mike Lynch yacht disaster left 7 dead

The Bayesian was a world-class yacht.

The 19th largest yacht designed by luxury Italian manufacturer Perini , it boasted a sleek interior design by French designer Remi Tessier, a double engine, and one of the tallest aluminum masts in the world. It won multiple awards, including for "best sailing yacht" the year after its release.

But, almost two weeks ago on Aug. 19, the luxurious vessel sank to the bottom of the ocean off the coast of Sicily in an internationally-followed disaster, dumping 22 people aboard into the water and leaving seven dead , including British tech magnate Mike Lynch and his 18-year-old daughter Hannah .

"The impossible happened on that boat," Giovanni Costantino, the yacht manufacturer's CEO, told Reuters.

In the wake of the disaster, an ongoing investigation into possible criminal errors committed by the Bayesian's crew and lingering questions surrounding its design underscore the need for proper yacht safety measures and practical ship designs, according to experts.

Italian prosecutors from a nearby town have now widened their investigation into possible criminal actions by the ship's captain in the lead-up to the shipwreck to include two additional crew members, a judicial source told Reuters on Wednesday.

Tim Parker Eaton and Matthew Griffith are now under investigation for manslaughter and shipwreck, days after news broke that investigators are probing whether Captain James Cutfield committed the same crimes.

Authorities are looking into whether Parker Eaton, a ship engineer, failed to protect the ship's engine room and operating systems. Griffith, a sailor on the ship, was on watch duty on the morning the ship sank.

Cutfield "exercised his right to remain silent" when investigators interrogated him on Tuesday, Giovanni Rizzuti, his lawyer, told Reuters.

"First, he's very worn out," Rizzuti said. "Second, we were appointed only on Monday, and for a thorough and correct defense case, we need to acquire a set of data that at the moment we don't have."

Rizzuti did not immediately respond to a request for comment emailed to him by USA TODAY.

Rescuers found the bodies of Chris Morvillo, an American citizen and lawyer for Clifford Chance, his wife, Neda Morvillo, Jonathan Bloomer, a non-executive chair of Morgan Stanley International, and his wife, Judy Bloomer, inside the ship two days after the wreck. Recaldo Thomas, the ship's cook who also went by Ricardo, was the first person pronounced dead in the disaster – his body was recovered on the day of the sinking.

Captains must follow safety procedures before storms

Costantino chalked up the boat's fate to a "series of indescribable, unreasonable errors" committed by the crew. The ship's crew made an "incredible mistake" in not preparing adequately for the storm, he said.

Costantino said the crew should have summoned passengers from their rooms earlier, as the storm picked up. The keel, a heavy weight under the ship to counterbalance the ship's large mast, should have been lowered, and portholes should have been closed – both factors that could influence whether the captain is found culpable, according to experts .

Captains should always check weather forecasts and look into local weather patterns, Mitchell Stoller, a maritime expert witness and captain, told USA TODAY . When in stormy weather, captains should also weigh anchor, so that a ship can float over unstable waters, he added.

"The general standard of care in this situation is to monitor the weather, exercise caution, have a night watch, have the engine going, ready to maneuver," he said.

Wealthy clients push for impractical designs, expert says

Costantino said the ship's design and construction was error-free. But one yacht design expert disagrees.

"There's so many other factors, and this huge, complex boat is part of it," said Tad Roberts, a British Columbia-based yacht designer who has worked in the industry for nearly 40 years.

The Bayesian's giant mast is part of a trend of bigger and bigger yachts, according to Roberts. He worked on the design of the Asolare, formerly the Scheherazade – at 154 feet long, the largest cold-molded sailing yacht in the world when it was released in 2003, according to its manufacturer, Hodgdon Yacht Services. "It's small today," Roberts added.

Roberts said problems emerge when yacht designers can't say no to wealthy clients' demands for more and more extravagant and overgrown designs.

"The clients are wealthy people. They are very used to getting whatever it is they want," he said.

But owners' requests can compromise security, he said.

"Owners are not naval architects," he said. "They don't understand the issues involved, and trying to explain to them may or may not work, but there are compromises being made all the time."

Yacht buyers are more likely to get a better boat than they would 50 years ago, since yachts are exported and built towards international standards, he said. Still, the worsening effects of climate change and extreme weather are growing risks to anyone sailing the high seas, he added.

"Be aware. That's the biggest part of it," he said. "There's a possibility that things could go bad, that there is risk involved."

Yacht owners install million-dollar, AI-powered security systems

Piracy on yachts is even rarer than sudden storms – only two cases were reported between 2019 and 2023, according to the International Maritime Bureau's Piracy Reporting Centre . Still, superyacht owners are investing in James Bond-esque technology in an effort to protect their vessels.

"There's definitely increased concern," said Frederik Giepmans, managing director of safety and security at MARSS, a technology company that offers high-tech surveillance and security systems for superyachts with a price tag "from the hundreds of thousands into millions," he said.

NiDAR, a software program manufactured by MARSS to provide protection for superyachts, can pick up on objects approaching a yacht from the air or water "while underway, at anchor and in port," according to the company's website.

The surveillance system uses artificial intelligence and machine learning to handle data from sensors monitoring all sides of a vessel. The AI system provides "constant, long range monitoring of the air, of the surface, of the underwater, to try and give the crew as much response time as possible," said Giepmans.

That way, yacht owners can pick up on any manner of approaching objects, from "small, fast craft approaching on the surface" to divers and submarines under the water.

But if a threat is detected, a yacht owner's "options to respond are limited," Giepmans said. "You can get out of the way. You can bring people to safety. But, for instance, a more military response is not available to you."

Giepmans pointed to a recent increase in attacks on commercial ships, like attacks carried out by Houthi rebels on ships cruising through the Red Sea. "There's a gap there in terms of security," he said. "Because there isn't really, right now, a way for commercial or private clients, to respond, perhaps, in an appropriate way to these threats."

Luxury yacht owners cruising off the coast of Monaco, for instance, shouldn't be as concerned about a direct threat to their security, as compared with boats sailing through other locations, he said. "It really depends on that, as to what extent they will go to protect their ship."

The greater danger could come from adverse weather events, as the planet warms every year.

Meteorologists have pointed to a water spout, a tornado that spun up over the water amid the storm that hit the Bayesian, as a possible factor in its wreck.

Water temperatures in the area were more than three degrees higher than average that day, the perfect conditions for the spout to form and the likely result of climate change, Rick Shema, a certified consulting meteorologist and former member of the Navy, previously told USA TODAY.

"The water spout was an uncommon occurrence. But again, these things happen, especially in warmer water," he said.

'it's just crazy': crews readying to tow 1 month after multimillion-dollar yacht capsized.

A month after a multimillion-dollar yacht capsized in the West River near Edgewater, crews are getting ready to tow it out of the area.

On July 27, the Love Bug took on water and made a mayday call before capsizing .

"It's just crazy, right? It's not every day a multimillion-dollar yacht gets capsized off your home," said Samantha Kaplan, who lives in the nearby Beverly Beach neighborhood near where the boat went down.

Some neighbors have had a front-row seat for all of it, even watching as all five people on the boat were rescued.

"They actually rescued people to that dock right there, so we saw people getting off the boat," said Ann Gaines, a neighbor. "I guess the owner and a couple people had already been rescued by another boat."

For nearly a month, neighbors looked at the boat lying on its side. They said after the remnants of Hurricane Debby blew through, artifacts from the boat washed ashore, including the boat's bar.

"Countertops and chairs and all of these liquor bottles, like Maker's Mark, and one of our neighbors gathered it all together and set it up like it was a bar," Gaines said.

"I found a frozen burrito that was no longer frozen, and added it to the bar collection," Kaplan said.

That's all gone now, and the Love Bug soon will be too.

Last week, salvage crews, barges and cranes surrounded the yacht and stood it upright. Crews had to rig it up and patch holes before the boat could be towed away to New Jersey.

Neighbors said it's been an interesting month, and even once the boat is gone, they will still have quite the story to tell.

"Every time we've had a person come and visit us the last few weeks, we're like, 'Also this is the million-dollar yacht that sank off our coast.' It's definitely been a good storytime for a little bit," Kaplan said.

The investigation into what caused the ship to take on water is ongoing.
