How Big Are Yachts? 5 Types Explained (With Numbers)

Yachts can come in a variety of sizes and weights. Before you purchase a yacht, you must know what size yacht you need.

The size and weight of the yacht that you need will depend greatly on what your intended use is for the yacht that you are purchasing.

Table of Contents

Here’s everything you need to know about the weight of yachts:

Here’s an Idea of How Big Yachts Are:

The term “Yachts” refers to a pleasure vessel that is at least 30 feet in length and has some type of cabin with some amenities. The biggest luxury yacht is 590 feet (180 meters) and 13,136 gross tons.

What Do We Mean When We Talk About Weight?

There are two types of weight for a boat, dry weight, and wet weight.

Dry weight is the weight of the boat without any fluids in the tanks. Wet weight is the weight of the boat with the fluids in the tanks.

You can also have a loaded weight, which is the wet weight, including any additional toys or equipment you have stored onboard.

What Do We Mean When We Talk About Length?

There are many different ways to calculate a boat’s length. For this reason, you want to make sure that you have a clear idea of what the length of your boat really is.

The boat’s registered length is generally the maximum overall length, which is the length on deck plus any bowsprit or swim deck.  The length of the boat on the waterline is also an important boat characteristic that you should know.

Due to the shape and construction of the hull, these numbers may differ.

For example, if you have a boat that has a 50-foot deck with no bowsprit, your registered length will be 50 feet.

Some boats are measured using “LOA,” otherwise known as length overall.

Why Is Knowing The Weight And Length Important?

The most important reason to know your boat’s weight and length is for when you choose to shop for trailers or even to determine if your vehicle can haul it.

If you try to tow a boat without an accurate representation of the weight or length, you can ruin your vehicle’s engine and even your towing equipment, not to mention have serious safety issues.

Another reason to know about your vessel’s weight is to know how much you can bring for your trip without packing more than the maximum weight allowed.

It is also important to know your weight and how it can affect your boat, especially when it comes to speed.

Different Types of Boats and Their Average Weight and Length

Below are some different types of boats and their average size and weight, and the factors that go into them.

1. Luxury Yacht

Yachts are normally classified as any watercraft that can be used for pleasure or sport and can range from 30 ft to over 100 ft.

While a yacht can be as small as 30 ft. long, a yacht is often considered a cabin cruiser until it is 39 ft. or more, then it is considered a proper yacht.

A yacht would be considered a large yacht once it’s length is over 79 feet. A yacht is considered a superyacht or megayacht if it is over 115 feet long.

The yacht the holds the record for being the longest yacht is 590 feet long. This yacht is called the “Azzam” and has held onto its title for over 5 years.

Because of the wide variety of sizes, the weight can vary greatly when it comes to yachts, and it is hard to nail down an average.

Some more distinctive differences between yachts include:

• These yachts are single-deck yachts with one living quarter below . They are often sleek and sporty.
• Also known as a sedan bridge or sport bridge yacht. This yacht has an area on top of the superstructure that features a view all the way around the vessel.
• This deck up top can offer a control station or even lounge seating, depending on its size.
• Also known as a pilothouse motor yacht, cockpit motor yacht, or sky lounge. This term can be used for any large recreational vessel that is motor powered.
• Usually, this means a multi-deck vessel similar to a flybridge but instead has a large interior deck.
• Often classified as a mega yacht, which is normally any vessel 80 ft. or more. This vessel is exactly what it sounds like.
• It is a yacht with three levels of enclosed living space.
• A sportfishing yacht is any yacht that is geared towards fishing.
• They often have areas designated to storage for rods, bait, tackle, and even areas to store the day’s catch.

2. Sailboats

Large sailboats are yachts propelled by sails and can be found in lakes, rivers, and even out on the ocean.  Today, they almost all have auxiliary power in the form of an engine.

While the weight and length of a sailboat can drastically vary, the average weight of a sailboat is about 8,800 pounds. This weight does not include added gear, equipment, or fluids.

The weight will vary greatly depending on the length of the sailboat. Sailboat lengths can range between 8 feet to 472 feet.

The 472-foot sailboat also carries three masts that tower at over 91 feet each. This can definitely add more weight than the 8-foot vessel.

Listed below are 6 examples of sailboats and their weights and lengths:

• Catalina 16 LOA: 16 ft. 4 in. Hull Weight: 430 pounds
• Hunter 22 LOA: 21 ft. 4 in. Hull Weight: 3,200 pounds
• C&C 27 LOA: 27 ft. 4 in. Hull Weight: 5,180 pounds
• Erickson 28.5 LOA: 28 ft. 7 in. Hull Weight: 8,500 pounds
• Pearson 39 LOA: 39 ft. 3 in. Hull Weight: 17,000 pounds
• Swan 48 LOA: 47 ft. 11 in. Hull Weight: 36,000 pounds

3. Speed Boats (Cigarette Boats)

Speed boats are sleek and built for achieving high levels of speed.

These boats are not made for watersports and should not be confused with ski boats.

A speed boat’s average weight is slightly less than that of a sailboat at roughly 8,000 pounds.

Some of the factors that determine a speed boat’s weight can include their length, engines, and sleekness.

Listed below are some examples of speedboats and their weights and lengths:

• Cigarette 38 Top Gun LOA: 37 ft. 8 in. Hull Weight: 9,175 pounds
• 32 Thunder Cat LOA: 32 ft. Hull Weight: 5,400 pounds
• M35 LOA: 35 ft. 4 in. Hull Weight: 9,250 pounds

4. Deck Boats or Pontoon Boats

Deck boats and pontoon boats both have large decks and are mostly intended for recreational use.

Pontoon boats have the lowest average weight at 3,100 pounds .

Because they do not have large hulls, they can be lighter and cut across the water easier than boats with larger hulls.

Listed below are some examples of deck boats and their weights and lengths:

• NauticStar 211 Angler (Deckboat) LOA: 20 ft. 9 in. Weight: 2,100 pounds
• Stingray 212SC (Deckboat) LOA: 21 ft. 11 in. Weight: 3,100 pounds
• Hurricane SunDeck 2690 LOA: 26 ft. 4 in. Weight: 4,475 pounds

5. Cabin Cruisers

Cabin cruisers are large boats that are sometimes looked at as mini-yachts.

These boats allow for sleeping accommodations and other luxuries afforded in their cabin space.

Like the sailboat, a cabin cruiser’s weight can vary. However, they do tend to have a smaller range than sailboats.

The average weight of a cabin cruiser is about 8,700 pounds.

One of the major factors in the weight of cabin cruisers is the size of the sleeping accommodations below. Some models of cabin cruisers can even sleep up to 10 people.

Listed below are some examples of cabin cruisers and their weights and lengths:

• Larson 274 Cabrio LOA: 28 ft. Dry Weight: 6,001 pounds
• Rinker 301 Express Cruiser LOA: 32 ft. Dry Weight 7,640 pounds
• Bayliner 285 SB LOA: 28 ft. 9 in. Dry Weight: 8,056 pounds

Picking a Yacht:

Yachts can vary in a wide array of sizes, weights, styles, and even purposes.

You can race them, fish on them, and cruise around at an easy pace.

You can take a day trip or even take personal cruises that last days or weeks.

With ample deck and cabin space that offers activities, sunbathing, kitchens, lounges, and sleeping quarters, a yacht is often the most comfortable way to experience the open water.

To choose a yacht, you will want to know what type of yacht you are looking for and what you want to use it for.

You also want to make sure when picking a yacht; you make sure you keep the weight and length in mind to make sure you have a proper towing vehicle and trailer for your vessel.

Easy Guide to Understanding Yacht Sizes

Navigating the sea of yacht choices can feel as challenging as sailing the seven seas themselves. But don’t worry, because understanding the classes and sizes of these luxurious vessels is the first step in charting your course to the ideal maritime experience. Whether you’re looking to host grand soirees on the deck, embark on long tranquil voyages, or enjoy sporty adventures on the waves, there’s a yacht out there that’s perfectly sized for your needs and desires.

What Determines a Yacht’s Class?

The class of a yacht isn’t just about its length; it encompasses several factors that contribute to the overall experience. These factors include the yacht’s size, style, facilities, crew requirements, and intended use. Yacht classes can range from sleek, racetrack-ready vessels to floating palaces designed for opulence and comfort. Understanding the classification can help you visualize what life at sea could be like aboard these different vessels.

Size Matters: The Various Yacht Size Categories

Yachts typically fall into specific size ranges, each offering its own unique set of benefits and considerations:

• Day Sailing Yachts : Under 30 feet in length, these are ideal for casual trips close to shore.
• Weekender Yachts : Typically 30-40 feet, they offer basic cabins suitable for short stays.
• Cruising Yachts : Usually measuring 40-50 feet, these combine comfort and storage for longer voyages.
• Luxury Yachts : At 50-100 feet, they often come with indulgent amenities and can accommodate guests and crew.
• Superyachts : Exceeding 100 feet, these are the epitome of nautical splendor, with bespoke features and unparalleled luxury.
• Mega Yachts : Over 200 feet, these are the rarified realm of extraordinary custom features and space akin to a floating mansion.

Deciphering Size and Space: Understanding Tonnage

Contrary to what it sounds like, tonnage doesn’t refer to weight. Instead, in yachting terms, it represents volume, and it’s a critical component in understanding the size of a yacht. This measurement can provide insights into onboard space, which can be a better indicator of whether a yacht will suit your space needs than length alone.

The Day-to-Day of Yacht Life: Layout and Usability

Imagining yourself aboard is essential. Consider how the yacht’s layout will cater to your lifestyle. Does the deck have ample space for relaxation and social gatherings? Are the cabins configured for privacy and comfort? Is the galley equipped for gourmet cooking, or will simple fare suffice? Envisioning each area’s functionality will guide you toward the right yacht size.

The Crew Factor: How Size Influences Staffing

Operating a yacht is no small feat, and the larger the vessel, the more hands you’ll need on deck. From captains and chefs to engineers and stewardesses, understanding crew requirements is an integral part of yacht ownership. Not only does it impact the day-to-day running of the yacht, but it also affects the overall experience for you and your guests.

Navigating Through the Seas: Technological Considerations

Advancements in technology have transformed maritime navigation, but with larger yachts, the complexity increases. Sophisticated navigation systems, stabilizing technology, and communication equipment are just a few aspects that play a bigger role in larger yachts’ operations, requiring a crew that is well-versed in these modern marvels.

If These Decks Could Talk: Entertainment and Amenities

With size comes opportunity, and larger yachts bring the potential for more lavish entertainment and amenities. Are you dreaming of a cinema room, a gym, or perhaps an onboard spa? The spectrum of customization is virtually endless, allowing your seafaring sanctuary to be as unique as your imagination.

Exploring the World in Style: The Yacht as Your Oyster

Think of your yacht as a gateway to the world’s most exclusive locales, accessible only by sea. The array of destinations you can explore is as boundless as the ocean itself. Whether it’s the cerulean waters of the Caribbean or the hidden coves of the Mediterranean, the right yacht size empowers you to embark on these adventures with ease and elegance.

Anchors Aweigh: Making Your Dream a Reality

Once you’ve familiarized yourself with yacht sizes and what they entail, the voyage toward purchasing your dream yacht begins. Knowing which size aligns with your aspirations is crucial to ensuring a future filled with unforgettable maritime memories.

Yacht Types and Sizes

Which yacht types and sizes exist in the world.

Are you curious which yacht types and sizes exist in the world? Spoiler: there are plenty!

In this article, we explore different types of yachts, such as motor yachts, sailing yachts, catamarans and trimarans.

We talk about their unique features, advantages and disadvantages.

We also cover the difference between serial, semi-custom and custom yachts and see which one is right for you. 

Finally, we learn about how yacht size is measured and how it affects overall yacht volume and operations.

Let’s get started! 

YACHT TYPES

If you consider buying a yacht, you need to decide on its type.

Which yacht type do you prefer: motor yachts, sailing yachts or catamarans?

These three categories are the most popular types of yachts, although there are also other ones.

Let’s look at each of them separately.

Yacht Types: Motor Yachts

Motor yacht is the most common type of a superyacht. Around 80% of world’s yachts are motor yachts.

These luxury boats are powered by strong engines, do not have sails and over time have become symbol of a classy and laid-back lifestyle.  

Pros of Motor Yachts: 

• Powerful and fast 
• Greater technological advances 
• Greater deck space, more living volume 
• Easier to find suitable crew members 
• Easier to operate than a sailing yacht 
• Easier to host guests of all personalities 

Contras of Motor Yachts:

• Less sustainable, higher fuel consumption 
• Less adventurous feel (if you are looking for it) 
• Shorter range (can only be powered by motor) 
• Engine noise 

Motor yacht is probably the first thing which comes to your mind when you think superyachts.

Classy and sleek design, plenty of deck space, comfortable staterooms and lots of entertainment options – all this you can find aboard a motor yacht.

Motor yachts come in different types and sizes and with different purposes. The latest trend is explorer motor yachts, which are explicitly equipped for cruising in cold polar regions.  

Yacht Types: Sailing Yachts

Sailing yachts are the second most popular yacht type. If you love the wind and want that classy sporty feel while aboard, then a sailing yacht is the right yacht type for you.

Another advantage is that when not powered by motor, sailing yachts are very quiet. It is only the sound of waves and wind (and an occasional seagull) around you.   

Pros of Sailing Yachts: 

• Unique feel of adventure 
• Can combine peaceful cruise with racing  
• Very quiet when powered by sail  
• Lower fuel consumption 
• Lower maintenance cost 
• Can sail in shallower waters  

Contras of Sailing Yachts: 

• Tend to be slower that motor yachts (in case you like speed) 
• Less stabilization  
• Smaller cabin space 
• Might have less lifestyle equipment available (Jacuzzi, gym, cinema) … 

There are only two types of people out there: sailing yacht fans and motor yacht fans. Rivalry between fans of the two yacht types has become legendary.

Probably, you already know which group you belong to. Nevertheless, we still recommend you charter both sailing and motor yachts to be sure you are making the right choice. If you are still unsure, read about the third yacht type below. 

Yacht Types: Catamarans  

Catamaran is defined as a vessel with two parallel hulls which are joined together. Due to its form, catamaran is the most stable of all yacht types.

If you are looking for stability and comfort, or have family members who easily get seasick, buying a catamaran is a valid option to consider. 

Pros of Catamarans: 

• More fuel efficient & sustainable 
• More stability  
• Can be used in shallow waters 

Contras of Catamarans: 

• Less volume for staterooms 
• Higher dockage rates than for a monohull 
• Different sailing feeling compared to a sailing boat 

Catamarans offer a great opportunity for taking family vacations, which will leave every family member happy. Since they are more difficult to sink, they are also considered the safest boats.

If you are looking for extra stability, comfort and space, but also do not want to compromise on adventures and possibility to explore shallow waters, catamaran is right yacht type for you. 

Yacht Types: Trimarans 

Big brother of a catamaran, a trimaran, has even three hulls – one main hull in the center, and two smaller hulls on each side.

You will not see them as often, but there are certainly also big fans of trimarans out there. Trimarans are designed for racing or leisure but are also widely used for military and shipping purposes. 

YACHT PRODUCTION TYPES: SERIAL, SEMI -CUSTOM, CUSTOM YACHTS

Now that we’ve covered yacht types, let’s investigate which production options are out there. Unlike the automotive industry where most of the car models come from production lines, the yachting world offers future owners more possibilities.  

SERIALS YACHTS 

This is the most common and less expensive way to get to your new dream boat. Serial or production yachts are yacht models which are produced by shipyards in various quantities based on model and size.

Serial does not mean that you cannot tune it to your taste though. Manufacturers offer different sets of modifications with certain yacht models. You will likely get to choose between several layout models and different equipment options.

Obviously, if you order a newly build yacht, you are likely to get more space for your improvements, than if you decide to refit an already existing yacht. 

SEMI-CUSTOM YACHTS  

A good way for owners who wish more character and comfort to their boats but at the same time do not want to order a fully customized vessel, is to order a semi-custom yacht.

Semi-custom yachts stand between serial and fully customized boats. You save a lot of time and effort by picking an existing engineered platform from which to start planning.

Then, together with experienced naval architects and designers, you enhance it up to your expectations by customizing layout (possibly including superstructure) and interiors.

Ordering a semi-custom yacht gives you more freedom to decide how your yacht will look like. Construction time is also much shorter in comparison with a fully customized yacht, since many parts are already designed, engineered and possibly even pre-built.

By ordering a semi-custom yacht, you can shorten construction time from two – three years up to several months!

Shipyards are also less likely to fall behind the delivery schedule, since they have produced similar yachts before and know which time is needed for delivery.

Most semi-custom yachts are designed to suite majority of potential future owners, which means that layout, size, engineering etc will be well thought-through in advance.

Due to extensive previous testing & refining of semi-custom hulls by the shipyard, it is possible that your new yacht will turn out more reliable and problem-free than a fully customized yacht. 

CUSTOM YACHTS 

If you wish to be unlike anybody else and want to take your dream a step further, a fully custom-built yacht is exactly what you need.

Almost anything is possible and achievable in today’s superyacht building industry. The only considerations are your budget and international safety and security standards, more on which you can read in our article on Safety and Security Onboard Superyachts. 

With a custom-made yacht, you can be sure you will get exactly the boat you want, tailored just for your preferences, no other yacht in the world being similar.

Consider longer delivery time and substantially higher cost, since R&D expenses are not shared between yachts of the same series.

Many owners buy a smaller replacement yacht, while they are waiting for their customized dream boat to leave the docks. 

A fully customized superyacht is surely the most exclusive type of a yacht one can own.

Yacht Sizes

Now let’s look at different yacht sizes. But first, let’s find out what yacht size actually is.

How is yacht size measured?

Length Overall (LOA) is the most widely used metrics of yacht length. It is measured from the aftmost tip of the hull to the furthermost point of the stem, measured parallel to the waterline. It is probably the only yacht length definition you need to know as an owner.  

*For yachting geeks out there, here are other yacht size definitions used in the industry:

Length of Deck (LOD) : deck length excluding bow sprits and other projections. Makes particular sense for sailing boats, since their Length Overall can considerably vary from their Length of Deck.

Length of Hull (LH or LOH): Length of hull including fixed fendering but excluding any bow sprits. It can be shorter than LOA.

Length of Waterline (LWL): length of a boat at the level where the boat sits in the water.

Interesting fact: Did you know that with each additional 1 meter of length, the internal volume of a yacht increases by 6-7 cubic meters? A 40-meter yacht is not just twice longer than its 20-meter companion. According to Cube Law, it is also 6-7 times larger in volume!  

Motor yacht sizes by group

Let’s look at different sizes of motor yachts. To make things easier, we divided them into 4 groups.  

Please note that the following crew and guest numbers per yacht size are only approximate.  

Factual crew numbers will depend on specific yacht length, cruising style, owner preferences and whether the yacht charters or not.

Factual guest numbers will depend on yacht registration type, especially with larger yachts.

22 – 40 meter motor yachts

Motor yachts in of this size are most likely serial production yachts. This means that you can buy a specific yacht model which has been designed before, and choose your own details, such as finishings and furniture.

Yachts of this size will need 4-6 crew members: yacht captain, one or two deckhands, one or two stewardesses, a yacht chef, and presumably an engineer.

22-40 meter long motor yachts normally can host up to 8 guests.

40-60 meter motor yachts

Motor boats of 40 meters length and larger are considered superyachts also within circles of superyacht industry professionals.  

This is where operations and crew requirements become considerably more sophisticated. There are also more semi-custom and custom boats in this size segment.

A 40-50 meter motor boat will require a crew of approximately 9-13 crew members, depending on specific owner requirements and cruising / charter preferences.  

A possible crew setup would be: yacht captain, first officer, bosun, two engineers, three or two stewardesses, two deckhands, one or two chefs (often a guest and a crew chef).

Crew of a 60 meter motor yacht will count around 20 members.

40-60 meter long motor yachts normally can host up to 12 guests.

60 – 80 meter motor yachts

Here the yachts grow much larger, and so do the costs of maintenance.

A yacht of 60 meters length will have a crew of 20-23 members. A yacht of 80 meters length can have a crew of up to 80 members.

The maximum number of guests will depend on yacht registration type. Many owners choose to keep maximum of 12 guests, since it allows for a simpler regulation regime.

80 – 180 meter motor yachts

A 100 meter motor yacht will require 80-100 members crew. Its tonnage will exceed 500 GT, which means that the yacht will fall under more regulations: STCW, SOLAS, ISSC, ISM and others.

A 170 meter motor yacht can have up to 100 crew members.

The largest yacht worldwide at the time of writing is Azzam, at 180 meters built by Lürssen. Azzam can host 36 guests and a least 80 crew.

Maximum guest number on a yacht of this size can still be only 12 guests. But if the yacht is registered as a passage vessel, it can be significantly more.

How does yacht size affect my yachting experience?

Size does matter after all.

Let’s look at factors that change with the growing size of a yacht.

While thinking of upgrading to a bigger vessel, do not forget that as the yacht size grows, following factors also increase: 

• Yacht price 
• Availability and price of marina dockage 
• Fuel consumption 
• Number of full-time crew members 
• Time you can spend away from ports 
• Quantity of water and other supplies the yacht can carry 
• Functionality and entertainment options 
• Complexity of repairs  
• Applicability of laws & regulations 
• Time needed to sell the yacht  

Budget is the main factor which determines how big your boat can be. To learn more about the cost of yacht ownership, read this article.

During the past decade, superyachts increased in size dramatically, and this trend continues. According  to an article  by Boat International, there has been around 10.000 yachts over 24-meter LOA in the world. Around 80% of them were motor yachts.

Most of the owners start small and upgrade their boats over years. Once you owned a smaller yacht for some time, you will understand exactly what you love about it.

Also, you will know what you want to improve. So why not initiate a new-build of a new more exciting and possibly larger boat? You can still have the older yacht at your disposal, while waiting for the new delivery.  

SUMMARY: YACHT TYPES AND SIZES

In this article, we classified all yachts into 3 main types: motor yachts, sailing yachts & catamarans. We also discussed their pros & contras.

We explained the difference between serial production, semi-custom and custom yachts.

Finally, we learned how yacht size is measured and how it affects various aspects of yacht operations. We looked at crew and guest numbers for each yacht size.

Yacht Classifications

• By Dudley Dawson
• Updated: July 17, 2009

ytgjul17perf525.jpg

Let’s take a peek into the dark back corner of a London pub a couple hundred years ago, when Britain was the unquestioned ruler of the sea, as a group of Lloyd’s of London insurance underwriters licked their financial wounds from the latest loss of a cargo ship to Davy Jones’s locker. They’d had enough, and proposed to form an independent society to make ships safer by developing standards for construction, operation, and maintenance. Thus was born Lloyd’s Register of Shipping, no longer affiliated with Lloyd’s of London, but still the granddaddy of maritime classification societies.

The concept was so successful in improving safety and cutting losses that spinoffs and imitators soon appeared in other seagoing nations. There are now ten full members and one associate member of the International Association of Classification Societies ( www.iacs.org.uk ). Not all of them class yachts, and of those who do, not all class smaller yachts. The American Bureau of Shipping (ABS), for instance, does not class yachts under 24 meters, or about 79 feet, in overall length.

Each society also has different sets of rules and guides, several of which will be applicable to any given yacht. While national codes, such as the U.S. Coast Guard regulations, and international treaties, such as SOLAS, are mandatory, classification is in most cases voluntary. A shipowner or yachtowner elects to have his vessel classed in order to better assure a certain level of sound design and construction, and consequently, to reduce insurance premiums and losses.

Although there are differences in the details, the societies have much in common. Each issues written rulebooks and guides for use by designers, reviews and approves the vessel plans in advance of construction, and employs dedicated surveyors to assure that the vessel is built in accordance with the plans. There are also periodic inspections by this same corps of surveyors throughout the vessel’s service life to check that it is being maintained to the required standards.

The voluntary nature of classification creates a number of possibilities for a yacht owner. He can pick and choose from the several classification societies that cater to yachts. For instance, an American owner having a fast yacht built in Holland could choose to have it classed by the Norwegian society, DNV (Det Norske Veritas). This is where those detail differences come in, as some designers consider the DNV construction rules for high-speed vessels to be more realistic than those drafted by some other societies. Such shopping for classification is commonplace, and that’s why you’ll find surveyors for each society in each shipbuilding nation. In an Italian yard, for instance, you might find an ABS surveyor working on one vessel and a Lloyd’s inspector working on another, alongside the first. In some cases, where the surveyors are independent, or “non-exclusive” in society parlance, you might find him wearing a DNV jumpsuit one day and ABS coveralls the next.

In addition to choosing his classification society, an owner can choose the level of involvement he wants with classification. Full classification means plan approval before construction, inspection and approval of both construction and installed equipment (anchors, engines, generators, etc.), and periodic inspections and required maintenance after delivery. An owner can also add various options, including most recently, an environmentally based endorsement of the yacht as “green.”

All of this comes at a price, of course, both in meeting the initial requirements and in continuing costs. Some owners view any financial outlay as justified in protecting their vessel and those aboard; others elect to have the yacht designed and built to class, and then drop the class designation when fees and mandated maintenance expenses begin to exceed the savings in insurance premiums.

Finally, an owner can opt to have his designer and builder use the written classification standards as a guide in the construction of his new vessel, without actually contracting with the society. This avoids some of the expenses of questionable value, such as factory testing and equipment certification. Then an independent non-society surveyor or project manager can oversee the construction up to delivery, and the captain, vessel management firm, or favorite boatyard can track maintenance requirements. It’s not official, but it’s still classy.

Classification of yachts by length. From motorboat to megayacht

•   Nautical Expert
• Yacht Buyer's Guide

Updated on March 17th, 2024

The difference between a motorboat, a motor yacht, a superyacht and a megayacht is only in size. We will not delve into the history of the origin of terms, for us it is not so important. In short, the name “yacht” previously denoted a class of vessels (moreover, sailing) that were used for official transportation from ship to shore or between ships.

Today we use the term “yacht” to refer to any vessel, sailing or motorized, designed exclusively for recreation and having the necessary amenities for a comfortable long stay on board. And the word “motorboat” today means the junior class of multi-purpose vessels, certainly motor ones, which can be both civil and official.

There is another definition of a yacht that is not tied to size: if it has a crew working aboard, it’s a yacht. But this definition is not precise, since a professional crew may be present on small boats, and at the same time absent on large ones.

A motorboat (or powerboat) has a stationary or outboard motor and is usually no longer than 7.6 meters (up to 25 feet). Work boats can be larger, as well as have a cabin-shelter, a simple galley and a latrine. The classification of a small fleet by size is very relative, here it is rather necessary to look at the purpose of the vessel, the level of its equipment and the degree of habitation.

Motor cruisers

Motor cruisers are vessels that are designed for recreation and travel both on inland waters and on sea routes, if their seaworthiness category allows it. A mandatory requirement for cruise boats is the presence of a minimum set of amenities: a cabin with sleeping places, a latrine, a galley, a shower.

Cruisers generally range in length from 7.6 to 13.7 meters (25-45 feet).

Motor yachts

Motor cruisers are followed by motor yachts. These are larger vessels for travel and recreation with stationary engines, allowing you to live on board for as long as you want, along with your guests, completely covering your needs for comfort and living space.

Generally speaking, motor yachts typically range in length from 13.7 meters to 24 meters (45-79 feet).

You must understand that in the official classification of yachts, when obtaining various types of licenses, we are not talking about the overall length (LOA), but about the load waterline (LWL), the length of which can differ significantly from the overall length. However, for general understanding this is not so important.

Superyachts

Yachts over LWL 24 meters usually already have a professional crew on board. Therefore, this class of vessels automatically belongs to the category of superyachts. Today, a crewed private large motor yacht is the norm, so the term “superyacht” tends to move farther along the length scale.

Megayacht is the informal name for the world’s largest motor and sailing yachts. The term is sometimes used as a synonym for superyacht, but it mostly refers to floating palaces over 70 meters (200 ft) in length.

If you go even further, you can even find the expression “gigayachts”, but in the yachting industry it is practically not used, and its definition is rather vague.

Boat Size Classifications & Requirements

Boat Classes By Length

Federal and state law requires that you have specific safety equipment on board depending on the class of your boat. To know whether you need flares, a fire extinguisher, a flashlight, an air horn or all of the above, you'll need to know the boat's class. Boat classes are determined by boat length. Let's review the four different classes of recreational boats as determined by length.

Boats measuring less than 16 feet.

Boats measuring more than 16 feet but less than 26 feet.

Boats measuring more than 26 feet but less than 40 feet.

Boats measuring more than 40 feet but less than 65 feet.

How To Determine a Boat's Size

To find out a boat's length, measure along its center line from the outside of the bow to the outside of the stern. That means any attachments, such as swim platforms or wakeboard towers, don't count towards its length.

Blog | Owner’s Guide to Yacht Classification

Yacht classification is a system used to categorize yachts based on various factors such as size, construction, and intended use. The specific classification categories and requirements can vary between different yacht classification societies, but some common classifications include:

• Pleasure Yacht: A yacht intended for leisure use, typically not engaged in commerce.
• Charter Yacht: A yacht that is available for hire for pleasure use, also known as commercial yacht.
• Large Yacht: A yacht that exceeds a certain size or gross tonnage.
• Small Commercial Yacht: A yacht that is used for commercial purposes but does not exceed a certain size or gross tonnage.
• Passenger Yacht: A yacht that is used to carry passengers for hire.
• Workboat: A yacht or vessel intended for work-related use, such as a survey vessel, cable layer, or other specialty use.
• Ocean Going: Yachts that are able to make ocean passages and are built and equipped to meet the requirement of such voyages
• Coastal: Yachts that are intended to operate in coastal and sheltered waters and meeting less stringent requirement than ocean going yachts.

The main differences between yacht classification societies are their specific rules, regulations, and requirements for yacht classification. While many societies have similar overall goals of ensuring that yachts meet certain standards of design, construction, and maintenance, they may have slightly different interpretations of these standards and how they should be applied.

Some societies may have stricter or more detailed rules and regulations than others. For example, one society may have more stringent requirements for fire protection, while another society may place more emphasis on stability calculations.

Another difference is the type of yachts they cover and the services they offer. Some societies focus primarily on pleasure yachts, while others also cover commercial yachts and workboats. Societies may also offer different levels of classification, such as “unrestricted” or “restricted” class, and this might vary depending on the intended use of the yacht.

Lastly, some societies have a more global presence than others, or have more experience or expertise in certain types of yachts or regions. This can be important for yacht owners who plan to take their vessel to different parts of the world and may need to comply with different regulations in different countries.

In short, yacht classification societies are similar in their overall goals, but they can have different rules, regulations, and requirements for yacht classification, different services and different areas of focus. Yacht owners should research and compare different societies to determine which one is the best fit for their specific needs and intended use of the yacht.

There are several yacht classification societies that provide certification and inspection services for yachts and other small vessels. Some of the most well-known include:

• American Bureau of Shipping (ABS)
• Bureau Veritas (BV)
• Germanischer Lloyd (GL)
• Lloyd’s Register (LR)
• RINA (Registro Italiano Navale)
• Det Norske Veritas (DNV) now known as DNV GL

These organizations are responsible for ensuring that yachts and other vessels meet certain standards of design, construction, and maintenance, and they issue certificates of compliance to vessels that meet these standards. They also conduct periodic inspections to ensure that vessels continue to meet these standards over time. Some of them also provide additional services such as collision avoidance, navigation and stability calculations and other specialized services.

Introduction To Different Types Of Yachts

We have discussed the differences between cruise ships and their older counterparts, ocean liners in one of our previous articles. We have also learned about the various types of cruise ships.

In this article, we shall discuss the types of yachts.

To begin with, what are yachts? Yachts are those small to average-sized vessels used for pleasure, vacation, or sports activities like racing. The most distinct feature that distinguishes yachts from any other boat or vessel is their aesthetics.

Yachts are attractive and sleek in appearance, have narrow and streamlined beams, and are often pleasing to the eye. However, size is also another important parameter taken into consideration.

As per classification rules, a vessel dedicated for the aforesaid purposes is deemed to be a yacht only when it is over a certain length of at least 10 meters or 33 feet.

Though sizes of yachts can be as large as more than 70-80 meters, they are rarely 100 meters or more. Larger vessels of such extents come under the purview of cruisers or passenger ferries as discussed before. A handful of exceptions exist.

The private megayacht Azzam, having a length of 180 meters, is the longest existing motor vessel in the world to be classified as a yacht.

Types of Yachts 

Based on length and size, yachts can be classified into the following categories:

Megayachts: These are the largest of their kind. Most yachts under this category have lengths of over 50 meters. They are used for leisure or recreational purposes and are suitable for large families or groups. Most of such yachts are owned and operated by organizations similar to cruise lines but private ownership also exists. These vessels have dedicated crew to cater for the services of passengers. In terms of facilities and amenities, they are very much close to luxury cruisers and are often replete with everything from swimming pools to pubs, cafeterias to movie halls, gyms to restaurants, suite rooms to conference banquets. Of course, provisions of all these depend on the size of the vessel.

Superyachts: These are lesser in size than the former. Their average length ranges from 30-50 meters. They also have appealing features like Jacuzzis, sky lounges, dining rooms, and bars. Superyachts can be both motor-driven or have sails (shall discuss more on this later). They also are often served by professional crew members. Both superyachts and megayachts are also called offshore yachts for their ability to tread deeper waters.

Medium-sized luxury yachts: With lengths ranging from 20-30 meters, they are suitable for large families or tourist groups. They may have a small number of dedicated crew members. Though not having many amenities like their larger counterparts, they offer a significant degree of comfort and luxury. They operate near the shore or in rivers.

Smaller Yachts: These vessels range between 10 meters to 18 or 20 meters. Most of such vessels are privately owned and are used for purposes such as leisure or water sports. They can be both motor or sail-driven or a combination of both. They have the main deck and living quarters comprising of at most 2 or 3 rooms below it. These yachts may have a small promenade deck or a flybridge. These yachts are compact, streamlined, and aesthetically attractive. Such yachts have limitations for venturing beyond a certain limit of the sea or river.

By propulsion

Sailboats: Like most other ships, yachts have evolved from having prominent sails for plying in the waters by the virtue of wind forces to having motorized propulsions. Unlike cruisers and ferries which became popular at a much later date during the 17th or 18th centuries, yachts or the concept of pleasure boats saw their advent as early as the Pharaonic Egyptian era.

For several centuries, these pleasure boats were characterized by different forms and sizes of sails. The areas of the sails depended on the size of the vessel, of course, and were primarily composed of natural materials such as flax or cotton fibers.

However, with the introduction of synthetics, sails made of polyester or nylon became increasingly popular and have continued to be used to date. Sail yachts are of numerous types, most of their designs derived from traditional variants of monohull sailboats like sloop, catboats, cutter, ketch, or schooner.

These vessels can be single sail-single mast (like catboats), double sail-single mast (sloop), or other versions of multiple sails-multiple masts (like ketches or schooners). Though almost all modern yachts employ mechanized propulsion, many still feature sails simply for aesthetics (see gullet yachts below).

Motor Yachts: After the Industrial revolution, yachts, in tandem with other vessels, incorporated engines for their propulsion. Coal-fired steam engines used both fire-tube and water-tube boilers. Over the years, steam engines became superseded by modern fuel-powered combustion engines. Yachts feature both four-stroke gasoline engines, especially for smaller and high-speed designs, as well as two-stroke diesel engines, for larger designs. Yachts may use single or twin-screw propellers of 3-blade, 4-blade, 5-blade, or even 6-blade propellers based on the requirements.

Gulet Yachts: They are a hybrid of the above types and employ both sails and engines for propulsion. As mentioned above, often the sails, even when no longer required, are kept for aesthetic appearance.

Based on Hull Design

Monohull: Commonly, yachts are of monohull configuration. Such hulls can be either of displacement or planing type. For displacement-type hulls, the buoyancy is created by the displacement and such vessels have average speeds not exceeding a certain limit.

Planing hulls, as we know, are meant for high-speed crafts where a substantial portion of the hull weights at high speeds are supported by the component of hydrodynamic lift as opposed to the hydrostatic lift from buoyancy. These vessels have very low wetted surface area during high speeds (and thus less frictional resistance) and the forward portion of the hull mainly stays above the waterline.

During rest or low speeds, once again, they are supported by buoyant forces. Yachts with planing-type hulls are quite small in size and are primarily meant for pleasure or water sports activities. Some designs combine both the elements of planing and displacement characteristics forming semi-displacement hulls.

Multihull: Yachts can also be multi-hull configurations, i.e., catamaran (two hulls) or trimaran (three hulls) types. Catamaran designs are chiefly characterized by two slender hull structures joined by the extension of the bridge deck or a large crossbeam. These vessels are highly stable and seaworthy.

Trimarans have a central hull and are further connected to a pair of hulls on either side by beams, superstructures, or decks. Multihull yachts mainly rely on their inherent stability and are not very fast like planning crafts. As expected, they are very expensive in construction. They are mainly composed of fibreglass and other composites.

Based on Purpose

Cruiser Yachts: They are conventional yachts of varying sizes meant for passenger pleasure and vacationing. These vessels are permitted for long-distance travel up to moderate depths of the ocean. They are mainly of displacement type. Luxury yachts often come under this category.

Fishing Yachts: These yachts are chiefly built for fishing purposes as a recreational activity. These yachts have space for ample fishing equipment and gear and are characterized by open decks favourable for fishing as well as hauling up the catch. These vessels are permitted to venture into areas having the best chances of fishing but are barred from deeper depths of the seas.

Trawler Yachts: Their purpose is similar to a conventional fishing vessel designated for mass-scale commercial fishing. However, unlike the bland design of trawlers, these vessels imbibe some degree of aesthetics familiar to a yacht.

Sports Cruisers: These cruisers are meant for recreational or sports activities and short fast trips. Such vessels are mostly characterized by either planning or semi-displacement hulls. They are relatively smaller in size and thus accommodation spaces are limited. Such vessels have a stylish and sleek-appearing flybridge and an open deck for a better experience. Such vessels reach speeds from 30 knots to 50 knots. Sports yachts are also often deployed for racing purposes. They are sometimes also known as open yachts. For those willing to indulge in a bout of adrenaline rush like in sports cars, these yachts are the apt choice!

Sport Fishers: These vessels combine both the purposes of luxury as well as fishing. Like fishing yachts, they are equipped with fishing gear as well as have features for ample passenger comfort and amenities. They often have semi-displacement or planing configurations. During fishing activities, they are idle or operate at low speeds and during pleasure, they may be operated at high speeds. Though generally not very big in size, larger vessels with sizes around 30 meters exist.

Expedition Yachts: For those having an appetite for some real adventure or exploration, these yachts are just the right ones. They are designed for longer voyages and often receive permits for long-distance trips, often to uncharted and remote locations. Since adventure or exploration groups involve quite a number of people and unpredictable sea states, these vessels are significantly large in size. They are strict of displacement hulls, often strengthened to suit various types of conditions likely to be encountered. For those vessels venturing into icy waters, the hulls are designed and constructed based on Ice-Class regulations. From coral reefs to the wilds of the Pacific, such vessels are capable of literally traversing anywhere! Modern competent designs incorporate all elements of passenger comfort, luxury, amenities, power, endurance, strength.

Classic Yachts: Some still have a taste for vintage times. Classic yachts are the older restored and retrofitted vessels or newly built ones designed in a way similar to yachts built in the yesteryears. The hull is as per the older variants and often has sails. They are strictly for shallow water and near-shore leisure for those seeking a touch of royalty and the glorious past. These are mainly owned by vintage collectors or connoisseurs.

Rules are developed to establish standards for the structural strength of the large yacht’s hull and its appendages, and the suitability of the propulsion and steering systems, power generation and those other features and auxiliary systems which have been built into the ship to assist in its operation, and even pollution protection systems. A yacht may be maintained in class provided that, in the opinion of the Society concerned, it remains in compliance with the relevant Rules, as ascertained by a periodic or non-periodic survey(s). Today a vessel either meets the relevant Class Society’s Rules or it does not. As a consequence, it is either “in” or “out” of “Class”.

In summary, Class Notations on Yachts will tell you a lot about the building quality and condition of each vessel and its components on an annual basis, according to the excellence of its construction and its adjudged continuing soundness. A yacht that has been designed and built to the appropriate Rules of a Society may apply for a Certificate of Class from that Society or for a periodical survey (generally required every 5 years) meant for the Renewal of Class Certificate . Class Societies have often developed two separate sets of Rules for Commercial and Private Yachts . They can be applied to New Construction as well as Existing Yachts .

Classification Societies

Classification Societies play a fundamental role in today’s marine industry. A Society will act on behalf of ship-owners and builders to ensure high build quality and the safety of a ship’s main structural parts . Classification also provides a point of reference with regard to those who were involved in the supply chain including builders, charterers and insurers.

As an independent, self-regulating, externally audited, body, a Classification Society has no commercial interests related to ship design, shipbuilding, ship ownership, ship operation, ship management, ship maintenance or repairs, insurance, or chartering.

The process begins with the design and construction phases, focussing on the implementation and manufacture of key components as well as technical specifications. The standards which must be adhered to are dictated by the regulations of the chosen society and are published as rules, evolving continuously to incorporate new technologies and client requests via the advice of highly competent engineers and architects.

All Classification Societies waive liability for future faults as a surveyor can only record a vessel’s quality at the time of inspection; it is then the responsibility of the yacht owner to maintain the vessel and inform the society in the event of damage or structural alteration. Although the surveys are thorough, they do not cover all aspects of a ship’s build and operating service. This can include crew qualifications, navigational aids and manoeuvrability.

Classification Societies are often simply referred to as “Class Societies” or just “Class”. There are currently 13 members of the International Association of Classification Societies (IACS) , each with a unique set of rules, classification layouts and notations. Five of the biggest Classification Societies are listed below, along with their identifying signature, to denote a ship constructed under special survey in compliance with the Society’s rules, suitable for unrestricted sea-going service:

The marks following the Society’s standard signature are not interchangeable between organizations, meaning each letter or number will represent a different characteristic for each society. Each mark can be broken down to highlight a yacht’s capabilities, equipment or restrictions.

Each of the Classification Societies has developed a series of notations that may be granted to a vessel to indicate that it is in compliance with some additional voluntary criteria that may be either specific to that vessel type or that are in excess of the standard classification requirements.

The Classification of a yacht does not absolve the Interested Party from compliance with any requirements issued by Administrations and any other applicable international and national regulations for the safety of life at sea and protection of the marine environment such as SOLAS, ILLC, MARPOL, ILO or IMO.

Smaller vessels are categorized differently, adhering to different requirements and statutory regulations. With a heavier focus on passenger numbers and distance of operation from shore, the Maritime and Coastguard Agency (MCA) outlines guidance for UK vessels (up to 24 meters in length) which are used for charter or commercial use.

As RINA is today the most reputed Classification Society in the Mediterranean and a leader in the yachting certification business, developing and offering services of ships classification, certification, verification of conformity, inspection, and testing, we will hereby provide you with a summary of their more common Class Notations on Yachts , this will be helpful to identify these most peculiar symbols :

CLASS NOTATIONS – RINA

Main class symbol.

The main class symbol C is assigned to ships built in accordance with the requirements of the Rules or other rules recognized as equivalent and maintained in a condition considered satisfactory by the Society. The period of class (or interval between class renewal surveys) assigned to a ship is a maximum of 5 years.

Except for special cases, a class is assigned to a ship only when the hull, propulsion and auxiliary machinery installations, and equipment providing essential services have all been reviewed in relation to the requirements of RINA’s Rules.

With the 5 year class period is to be understood as being the highest class granted by the Society.

Construction Marks

The construction mark identifies the procedure under which the yacht and its main equipment or arrangements have been surveyed for the initial assignment of the Class.

Construction marks defined below are assigned separately to the hull of the yacht and its appendages, to the machinery installation.

The construction mark is placed before the symbol HULL for the hull, before the symbol MACH for the machinery installations, and before the additional Class Notation granted, when such a notation is eligible for a construction mark.

When the same construction mark is assigned to both hull and machinery, the construction mark is assigned globally to the ship without indication HULL and MACH after the main class symbol.

Hull Construction Mark (HULL)

• Construction mark ✠ is assigned to the hull when it has been surveyed by RINA during its construction in compliance with the new building procedure.
• Construction mark ✠ is assigned to the hull when it was built under the survey of another Society.
• Construction mark ● is assigned to the hull in all cases other than those listed above.

Machinery Construction Mark (MACH)

• The construction mark ✠ is assigned when the propelling and auxiliary machinery has been designed, constructed, certified, installed and tested in accordance with RINA Rules.
• The construction mark ✠ is assigned when the propelling and auxiliary machinery has been designed, constructed and certified in accordance with the rules of another society and installed and tested under the survey of RINA.
• Construction mark ● is assigned in all cases other than those listed above.

Navigation and Operating Notations

The navigation notation UNRESTRICTED NAVIGATION is assigned to a ship intended to operate in any area and any period of the year.

Restricted operating area notations are optional and will be marked accordingly like, for example, on a specified operating area or operation service within “x” miles from shore.

Additional Class Notations

An additional Class Notation expresses the classification of additional equipment or specific arrangement, which has been requested by the Interested Party. The assignment of such an additional Class Notation is subject to the compliance with additional rule requirements.

Some additional Class Notations, due to the importance of relevant equipment or arrangements, are assigned a construction mark. This is indicated in the definition of the relevant additional Class Notations. Class Notations which may be assigned to a ship are listed according to the category to which they belong:

Automated Machinery Systems (AUT)

AUT notations are relevant to automated machinery systems installed onboard ships.

Automated machinery systems (AUT – UMS (Y))

The additional Class Notation AUT-UMS (Y) may be assigned to yachts that are fitted with automated installations enabling machinery spaces to remain periodically unattended in all sailing conditions including manoeuvring.

Integrated Ship Systems (SYS)

SYS notations are relevant to the operation of integrated systems regarding navigation, machinery, communication and specific cargo, as applicable.

Centralised Navigation Equipment (SYS-NEQ)

The additional Class Notation SYS-NEQ is assigned to yachts which are fitted with a centralized navigation control system so laid out and arranged that it enables normal navigation and manoeuvring operation of the ship by two persons in cooperation.

Centralised Navigation Equipment (SYS-NEQ-1)

The additional Class Notation SYS-NEQ-1 is assigned when, in addition to the above, the installation is so arranged that the navigation and manoeuvring of the yacht can be operated under normal conditions by one person, for a periodical one-man watch. This notation includes specific requirements for the prevention of accidents caused by the operator’s unfitness.

Integrated Bridge System (SYS-IBS)

The additional Class Notation SYS-IBS is assigned to yachts which are fitted with an integrated bridge system which allows simplified and centralized bridge operation of all main functions of navigation manoeuvring and communication, as well as monitoring from the bridge of other functions related to specific cargoes and pollution; for passenger ships, heating, ventilation and air conditioning are also included in the monitored functions

Communication System (SYS-COM)

The additional Class Notation SYS-COM is assigned to yachts which are fitted with a local area network including the alarm, monitoring and control systems and computers used for management operations and external communication devices for reporting ashore navigation, maintenance and operational information.

Damage Stability (DMS)

The additional Class Notation DMS may be assigned to yachts complying with the damage stability requirements.

STAR Notation

General STAR is a System of Trace and Analysis of Records integrating rational analysis with data and records from ship-in-service concerning planned inspection and ship maintenance.

The additional Class Notation STAR-HULL is assigned to ships on which an Inspection and Maintenance Plan (IMP) for the hull is implemented.

The notation may be completed by the suffix NB when a structural tridimensional analysis has been performed for the hull structures, at the new building stage. The suffix NB is removed when the ship enters the STAR-HULL survey program through the implementation of the Inspection and Maintenance Plan (IMP).

The additional Class Notation STAR-MACH is assigned to yachts on which an Inspection and Maintenance Plan (IMP) for the machinery is implemented. This plan is based on a risk analysis review of the installation.

STAR Notation (STAR)

When yachts are granted both STAR-HULL and STAR-MACH, the two separate notations are superseded by the cumulative additional Class Notation STAR.

Crew Accommodation and Recreational Facilities (MLCDESIGN)

According to the Maritime Labour Convention 2006 Notation:

The additional Class Notation MLCDESIGN is assigned to yachts having crew accommodation and recreational facilities complying with the Maritime Labour Convention 2006 (MLC).

GREEN PLUS Notation (Eco-Friendly Yachts)

Issued in 2008 and updated yearly, the GREEN PLUS additional Class Notation has been revised in 2012 to cover new issues for seagoing ships and ships operated at a fixed location. The additional Class Notation GREEN PLUS is assigned to Eco-Friendly yachts compliant with the Society’s environmental protection framework of airborne gases, spillage/leakage of substances, oil, sewage, greywater, garbage disposal and noise mitigation systems to prevent pollution.

Safety Class Notation EFP (Bureau Veritas)

The following additional Class Notations are assigned to yachts complying with the requirements of this Section:

• EFP-A : for yachts having Enhanced Fire Safety Protection in accommodation spaces,
• EFP-M : for yachts having Enhanced Fire Safety Protection in machinery spaces,
• EFP-C : for yachts having Enhanced Fire Safety Protection in cargo areas,
• EFP-AMC : for yachts complying with all the requirements of this Section.

Yacht classifications, also referred to as classification societies or class societies the that rules are an integral element of owning a yacht and an important part of maritime safety. These classifications dictate the design, construction and ongoing maintenance of large commercial vessels and superyachts.

The classifications provide highly detailed and technical standards which cover the yacht’s hull, its engines, and key safety systems. Naturally technology is constantly advancing and so new safety features and procedures are frequently evolving to cater for this.

Standard Yacht Types

Yachts are typically segmented based on overall length and how many passengers they can accommodate. The standard yacht classification types are large yachts, sailing yachts, commercial yachts and private yachts.

Commercial yachts are those yachts which engage in commercial activities, i.e charter yachts. These yachts do not transport or carry any cargo and can carry no more than 12 passengers when underway. In contrast, private yachts are typical pleasure vessels used solely for recreational or leisure purposes.

Classification society

Classification societies are organizations which ‘set the rules’ that govern the construction, maintenance, and operation of yachts and vessels. Currently, there are a total of 12 members of the International Association of Classification Societies, of which the main societies involved with yachting are::

• ABS (American Bureau of Shipping)
• Bureau Veritas
• Lloyds Register
• RINA (Royal Institution of Naval Architects)

Classification societies were first started when insurance underwriters Lloyds of London set standards for the ships that they would ensure.

What is a flag state?

A vessel’s flag state is the jurisdiction or nationality under whose laws the vessel is registered or licensed.

The flag state has the authority and the responsibility to create regulations for vessels registered under its flag. These typically involve those relating to the inspection, certification, and issuance of safety and pollution prevention documents for the vessel.

Different flag states may perform inspections on the safety aspects of yachts using their own inspectors or use classification societies or other recognised organization to perform these inspections.

I have written a separate blog post which goes into further detail on Flag States and the importance of choosing the right flag for your yacht.

What is the classification process?

The first step of classification involves the assessment of a yachts design and regular inspections during the construction or conversion of a yacht. Once it is confirmed that all standards have been met, a certificate of classification is issued.

The certificate details the standard met, the intended use for the vessel, and whether the vessel should be used only in sheltered waters. The certificate is aevidence evidence that the yacht has been built too and meets industry standards.

In order to maintain classification regular surveys of the yacht are required. These surveys typically take place every 5 years. These surveys assess things such as the thickness of the hull, possible fractures, and other potential damage. They also consider the condition of electrical systems, machinery and equipment.

Mandatory Classification Certificates

There are a variety of different classification certificates. The number and type of mandatory certificates for a given yacht will depend on its size.

International Tonnage Certificate

This expresses the internal volumes of the yacht in gross tonnes. Unlike displacement tonnage, this does not quantify the weight of a vessel.

Large Yacht Code Certificate

This certificate covers navigational and signaling equipment, life saving appliances, fire protection, means of escape, and manning and crew accommodation. `

Class Certificate

This mainly deals with the yacht’s hull, machinery, electrical equipment, and outfitting.

International load line certificate

This certificate covers the weather tightness of the yacht

Safety Radio Certificate

This certificate only applies if the yacht’s gross tonnage exceeds 300GT. It covers radio communication and distress installations.

MARPOL Annex I Certificate

This certificate only applies if gross tonnage exceeds 400GT and covers the disposal of oil and bilge water

MARPOL Annex IV Certificate

This certificate only applies if gross tonnage exceeds 400GT or if the yacht is certified to carry more than 15 people and covers the disposal of sewage from ships

Marpol Annex V

This certificate covers the disposal of rubbish and applies to all ships

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 mains and auxiliary engines (NOx and SOx). Safety Construction and Safety Equipment

These cover machinery, electrical parts, life saving and navigational equipment for yachts with a gross tonnage above 500GT. International Safety Management Certificate

This only applies to yachts with 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 only applies to yachts and ships with a gross tonnage greater than 500GT and covers the anti piracy certification. A certified management company is requested to provide ashore assistance and establish onboard procedures and operational manuals.

Demystifying yacht classification A, B, C, D

N.B. For your information, a more recent article was published on 24 Oct 2022 on the same subject, click here for direct access.

Demystifying yacht classification :  Class A, B, C and D

Since 1998, CE certification is required for all recreational boats entering or being sold in Europe obliging boat manufacturers to respect certain building and security standards.  Therefore, yachts ( boats ) are classified into four categories depending on their aptitude to confront navigational conditions taking into account both force of the wind and height of the waves.  The categories are not to limit the area and distance of navigation (that is defined by security equipement onboard) but  to  sensitize the owner and/or captain of the boats capacities to navigate in complete security.

Let us start with the Beaufort Scale.   A scale for classifying the force of the wind ranging from 0 (calm) to 12 (hurricane).   It was devised by an admiral in the British Navy, Francis Beaufort, to uniform the description of the effect of different winds at sea.

There is a direct link between the Beaufort scale and boat classification.   For discussion purposes, we will use only the 6, 7 and 8 forces.

A Class A yacht ( boat ) is a vessel that is built to navigate the open ocean and surpass a force 8 on the Beaufort scale and surpass waves higher that 4 meters.   These yachts are constructed to be self sufficient in hostile seas.

A Class B yacht ( boat ) is a vessel built to navigate on the offshore waters (200 miles and less) and can substain UP TO force 8 and waves UP TO 4 meters.

A Class C boat is a vessel built to navigate inshore such as lakes, rivers, bays and close to the shore and can sustain UP TO force 6 and waves UP TO 2 meters.

A Class D boat is built for protected or sheltered waters such as canals, rivers, small lakes and sustain a force 4 and waves UP TO .3 meters (less that 1 ft).

With this said, you can understand that the Class A yacht ( boat ) respects a rigorous building code more so than a Class B and so forth.    But regardless of the class, it is strongly discouraged to navigate in a force 7 for the reasons of safety and comfort as « pleasure » should always be on the agenda.  Always consult the weather forecast prior to leaving any port and check hourly the weather situation.

Classification is very important and should be on your question list before purchasing any boat or yacht.

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 of yacht.

Also for a class A, the portholes will be more resistant against a sustained wave, the drains to evacuate the water more abundant and of good size, the joints of the hull more hermetic, in short everything is in place to prevent water from s’ infiltrate on board.

By way of information, let us quote for example all the Ferretti yachts (60 to 96 feet), Pershing (60 to 115), the Riva (44 to 122) are all of class A just like the Magellano range at Azimut including also the 66 Flybridge.

Ferretti yachts (500, 550, 670 fly and over), Pershing (7X and over), Azimut Yachts (62, 64, 66, 68 Fly and over, the Sport Series 7X and over, all Magellano) are Class A.  There are also other classifications such as RINA and American Bureau of Shipping, Bureau Veritas, Det Norske Veritas, Germanischer Lloyd, Lloyd Register, that are more precise regulations and we will cover this later in another article.

Below is the graph of the Beaufort Scale along with photos.

What are the Different Classes of Boats?

Classes of boats and types of boats are two different things. Every type of boat fits into one of four classes of boats. While a type of boat can vary significantly in appearance and function, class is easy to understand. Boat classes are all determined by the overall length of the vessel.

The class of a boat is significant for you as a boat owner. Boats classes are required to meet certain safety guidelines based on those classes. The size of your boat determines what you need to keep on board. Let’s take a look at the different classes of boats. We’ll also get into different types of boats and see where they fit in terms of class.

Class A Boats

Any boat that clocks in at under 16 feet in length. That means it could be:

• a fishing boat
• A personal watercraft
• An inflatable boat

Recreational boats that are less than 16 feet in length are not required to carry any day signals on board. That said, there are safety requirements. These are regulated by the US Coast Guard. It’s also worth noting that these regulations are slightly different for canoes and kayaks.

Canoes/Kayaks Under 16 Feet

For these vessels, a Type I, II, III or V personal flotation device must be available for every person on board. These need to be US Coast Guard approved flotation devices. They need to be the right size and wearable by the person who plans to wear them as well. If the person is not wearing it, it needs to be someplace they can reach it easily. We recommend anyone on a boat of this size keep their flotation device on at all times. The minimum requirement is that one be available and easy to reach. In an emergency, you can save yourself precious time by having it on already. This is especially true for children on boats.

Visual distress signals are required on the vessel if it’s being operated at night. Your night signal has to be made within the last 42 months as well.

Sound devices are required as well. A whistle is recommended but a horn will work also.

Other Boats Under 16 Feet

All boats under 16 feet require the same personal flotation devices. The rules for a kayak or canoe apply here as well. One for everyone on board that is accessible and wearable. A distress signal is also required for these boats. Sound signals are the same as for kayaks and canoes as well.

There are additional requirements for these kinds of boats if they meet certain conditions.

A B-1 fire extinguisher of any type must be on board any vessel under 16 feet besides a canoe or kayak. That is, if it has an enclosed engine, enclosed living space, or a permanent fuel tank.

A type I, II, or III Marine Sanitation device is required if the vessel has an installed toilet.

A backfire flame arrestor is required if the vessel has a gasoline-powered engine. The exception is if it is an outboard motor.

Enclosed engines must also have ventilation that meets Coast Guard standards.

Class I Boats

Boats that are between 16 feet and 26 feet fall under this classification. Any number of boats could fall into this class.

• Smaller deck boats
• Cuddy cabin boats
• Pontoon boats
• Aluminum fishing boats
• Wakeboard boats

All Class I boats must have one personal flotation device of Type I, I, III or V per person on board. In addition, one throwable Type IV device is required to be on board. Often people overlook these on tow sports boats. They will only think of the person looking for a thrilling ride water skiing as the one who needs a PFD. The Coast Guard requires them for everyone, however.

A B-1 fire extinguisher of any type is also required to be on board. This is true, again, if the engine is enclosed. It’s not required for outboard motor boats. However, as before, if there is an enclosed living space or permanent fuel tank, then you do need a fire extinguisher.

This size of boat requires specific distress signals. You need a minimum of three day use and night use flares. You can also have a non-flare substitute for day use in the form of an orange distress flag. A Non-pyrotechnic substitute for night use is an electric SOS light. Flares must have been made within the last 42 months.

A horn or whistle is needed as a sound signal.

Class II Boats

Class II boats are any vessel that span 26 feet to 40 feet. This can include

• Cabin cruisers
• Bowrider boats
• Trawler boats
• Runabout boats

These boats meet the same requirements for PFDs as Class I boats. That means every single passenger on board needs to have access to their own life jacket or other PFD. The acceptable types are Type I, II, III and V. And again a throwable Type IV is also required. These recreational boats can easily hold over one dozen people. Even if you’re freshwater fishing in shallow waters, these requirements must be met.

At this size, either one B-II fire extinguisher or two B-Is are needed. Remember, marine plywood isn’t able to stand up to fire well at all. The extra extinguishers could be a lifesaver at this size of a boat. Nothing ruins some relaxed cruising faster than a boat fire.

Visual distress signals on this kind of boat are the same as those for Class I boats. That means three day use and three night use. Three combination day and night use signals are also acceptable. These are essential for any overnight trips on the boat. Even high performance boats can run into troubles in the dark. Make sure any signal flares have been manufactured within the last 42 months.

Sound devices must be present as with lower boat classes.

Enclosed engines must also have ventilation that meets Coast Guard standards

This class of boat is also required to have pollution regulation placards. Your boat will need a 5″ x 8″ Oil Discharge placard and 4″ x 9″ Waste Discharge placard.

Class III Boats

These boats range from 40 feet to no more than 65 feet in length. This can include

• Cigarette boats
• Sport fishers

These are the largest class of boat available to typical boat owners. For these, the same flotation device standards apply as they did for Class II. That means one PFD of Class I, II, III or V is required for every passenger on board. Since different types of boats can carry passengers in greater numbers, this needs to be respected. Make sure every single person knows where the PFD is and how to wear it. Each person must have one that fits properly.

In terms of fire extinguishers, the rules change again with Class III boats. You will need one B-II extinguisher and one B-I extinguisher on board. Alternatively, you could have three B-I extinguishers handy.

Visual distress signals and sound signals are the same as the requirements for smaller class boats. That means three day use and three night use signals. An orange signal flag may substitute one of the day use flares, and an electric SOS light can substitute for one of the night use. A horn or whistle is also required.

This class of boat is also required to have pollution regulation placards. Your boat will need a 5″ x 8″ Oil Discharge placard and 4″ x 9″ Waste Discharge placard. If the vessel has a galley then it must also have a waste management plan.

At this length, the boat must also have the Inland Navigation Rules on board. This is the “Rules of the Road” that govern boating.

Boats Over 65 Feet

Some yachts and things like a ferry boat can easily be over 65 feet. These no longer qualify as subject to small boat regulations. Typically no one is going to own a personal watercraft of this size. The Coast Guard does have regulations in place if you are on a large vessel such as this, however. These apply to vessels from 65 feet up to 165 feet. After that, vessels are typically considered research, commercial, or military.

The rules regarding flotation devices remain static here. One Type I, II, III or V PFD for every passenger on board. In addition, one Type IV throwable device. It’s worth noting there that the “Type” system will not be around forever. The Newton system is slowly being phased on. Newtons measure pounds of force and help indicate how much a PFD can keep afloat. This buoyancy rating in Newtons has been in place since 2019. The transfer is going slowly to allow people time to adjust. Most PFDs you purchase now will explain buoyancy in Newtons.

For instance, a Type II flotation device is equivalent to a current PFD that is rated for 70 Newtons. This device should be able to keep most people floating face up in the water. Type III devices will be replaced with 70 Newton rated PFDs that do not turn you face up. Each device has a Newton rating plus icons. These explain how much weight the PFD is meant to keep you afloat and how it floats you. In several years time, all PFDs will follow these guidelines. That said, old PFDs are still perfectly legal and usable.

For fire extinguishers, weight becomes a factor at this size. Vessels that weigh up to 50 gross tons need one B-II extinguisher. Over 50 gross tons requires two B-II extinguishers on board.

Visual and sound signals are the same for the previous class of vessels. This class does have a variation in sanitation requirements, however. A Type II or Type III marine sanitation device is required for this size of a vessel.

Additional requirements are the same as for the previous class. This includes sanitation and ventilation. The backfire flame arrestor must meet the same requirements as well. A copy of the inland navigation rules must also be on board the boat at all times, also.

What Class are Fishing Boats?

There are dozens and dozens of kinds of boats in the world. You have banana boats, log boats, bass boats and so many more. That’s why the class system is broken down by length. It makes it much easier to categorize a boat in these simple terms rather than trying to manage each type individually.

As a result, something like a fishing boat does not necessarily fit into one class. Your fishing boat could easily fit into literally any one of these classes. Remember, a fishing boat is not even technically a specific kind of boat. A fishing boat is just a boat from which you go fishing. A pontoon boat or some high performance boat could be a fishing boat. An inflatable dinghy could be a fishing boat. There is no standard for that particular description of a boat.

Does a Fishing Boat Need All The Same Safety Gear?

Some people question the application of safety standards. A Class I boat that only has one person on board seems different than one with ten people on board. But the rules are adaptable. If you are the only passenger on the boat then you only need one flotation device. You only need the fire extinguisher if your boat meets the requirements for it. That means something other than an outboard motor.

Man powered boats do not require the same level of safety and concern that power boats do. That’s why canoes and kayaks are exempt from requiring a fire extinguisher. After all, what would be the point? But just because your boat doesn’t have a swim platform or whatever doesn’t matter. Smaller boats or bigger boats all have the same potential to get into trouble. These rules are meant to help prevent that as much as possible. What About Pontoon Boats and Deck Boats?

No matter what kind of boat you’re on, the Coast Guard requirements apply evenly. Again, this can sometimes seem unnecessary. Something like a ski boat may seem more dangerous than cruising around on a deck boat. If you’re just relaxing on inland waters trying to catch largemouth bass, it can seem like overkill. But these measures are designed to ensure safety. In fact, these are the minimum requirements that the Coast Guard has implemented.

Some boaters prefer to have additional measures in place. For instance, as we said above, we recommend wearing a PFD at all times. This is not specifically required, only that the PFD be wearable and accessible. We feel that, the more people on board a boat, the more important it is to make sure everyone is wearing a PFD. This can cut down on wasted time and confusion if an accident happens later. If everyone scrambles for a PFD at the same time, a bad situation could easily become worse.

The Bottom Line

Boat classification has no effect on how you enjoy your boat. It also doesn’t change what you are allowed to do on your boat. The only purpose of classifications is to account for safety on board. Larger boats need to take more care in keeping the boat and passengers safe. Understanding the requirement is key to ensuring the safety of everyone on the water. Make sure you know the full dimensions of any boat you plan to take out onto the water. Once you are aware, you should always do a pre-departure check of the boat.

It’s important to know if you have all the safety gear every time you head out. Make sure the personal flotation devices are all in good working order. Check the date on all flares or visual signals to make sure they meet requirements. Also, check the date on your fire extinguishers before heading out as well. Old gear should be replaced immediately. It’s better to have it and not need it than to need it and not have it.

Keep yourself and your passengers safe and you’ll be having a great time on the water.

Yacht owners guide to Classification Societies

Classification societies (also known as ‘class’ societies) make an important contribution to maritime safety. Their engineers and surveyors, who are experts in the technical aspects of yacht construction and maintenance, have two distinct but related roles.

The first is to research, establish and apply standards for the design, building and maintenance of trading ships and yachts. Known as the ‘rules’ of the society, these standards are highly detailed and technical and cover the strength and integrity of the yacht’s hull, engines and key safety systems, but not aesthetic or operational elements.

The experts’ second role is to perform much of the ‘statutory’ inspection work – required by international conventions – for smaller nations that maintain a registry for flagging yachts, but do not have sufficient expertise of their own.

Occasionally, flag states may insist on a yacht being classed by an approved society, irrespective of size or use

The two roles can overlap. If a flag state’s technical requirements are sufficiently similar to a society’s rules, that society could undertake limited classification and statutory compliance responsibilities during a vessel’s construction, which saves re-inventing the wheel. Further, under the rules of the society, the flag state administration may have to be informed if a yacht falls foul of the rules, which, in turn, may invalidate the flag state’s equipment and safety certificates.

Societies often offer additional consultancy services, going beyond basic classification, during building and refits. It is also possible to have even fairly modest yachts built according to class rules, which are usually higher than those imposed by law and can boost resale value.

Compulsory classifications

Classification is voluntary, unless a flag state requires it, typically by virtue of the International Convention for the Safety of Life at Sea (SOLAS).

SOLAS demands that certain yachts be designed, constructed and maintained in compliance with the various requirements of a recognised society, or with the equivalent flag state requirements. This applies to yachts that undertake international passages on any sort of commercial basis, and which carry more than 12 guests, are of at least 500 gross tonnes, or both.

Occasionally, flag states may insist on a yacht being classed by an approved society, irrespective of size or use. In any event, classification is often needed to reassure any banks that hold security on the yacht and would otherwise have no way of ensuring that the asset is not depreciating excessively.

Also, owners of larger yachts may also find it hard to obtain insurance at reasonable rates without classification. For the insurers’ peace of mind, policies commonly insist on the yacht being classed, and maintained ‘in class’, by a society agreed on by the underwriters, with all the experts’ recommendations being carried out as directed. If this is agreed to in the policy but then not adhered to, insurers could walk away without paying a penny in the event of a claim.

In fact, the societies were a product of the fledgling insurance industry. When this new sector was developing at the tables of Mr Lloyd’s coffee house in 18th-century London, it became apparent that the insurers’ knowledge of the ships they insured was less than perfect. As construction methods varied, the vessels were classed according to build quality and condition. The idea worked, and Lloyd’s Register was born. Insurance premiums could at last accurately reflect the risks, with higher build specifications and better maintenance being rewarded with lower premiums. Soon societies were being established around the world.

Today’s classification societies

There are now dozens of organisations worldwide providing classification services but only 13 make up the proudly self-regulating International Association of Classification Societies. Members are independent and non-profit-making and provide services to nearly all the world’s commercial and leisure tonnage. IACS itself also has the capacity to develop rules in conjunction with the International Maritime Organization.

Classification process

The initial process of classification involves assessments of drawing-board designs and attendance throughout construction or conversion. Once a survey has confirmed that these rules have been met, a certificate of classification is issued. This summarises the standards met, the broad intended use of the vessel and whether she should be used only in sheltered waters.

Crucially, the certificate is not an express guarantee of safety or seaworthiness, but merely evidence that the yacht meets certain standards.

Being maintained in class is achieved through regular surveys, which, to simplify matters, are carried out regardless of the yacht’s circumstances. Surveys performed to renew the classification, known as ‘special’ surveys, take place every five years, which can be extended by up to three months if necessary. The examinations can be surprisingly scientific in nature, with various tests conducted to assess the thickness of the hull, possible fractures and other forms of deterioration, as well as the condition of all the principal items of machinery and equipment.

The certificate is not an express guarantee of safety or seaworthiness

An intermediate survey is then carried out three months either side of the third anniversary. On top of this, annual surveys, which need not be so thorough, are conducted three months either side of the anniversary date.

Of course, yachts are often subject to modifications, as the owner’s whims and new regulations dictate. They may also be subject to heavy-weather damage, accidents and neglect. For these reasons, they are also be subject to ad hoc surveys.

Where any survey raises concerns, class can be suspended or withdrawn, depending on the nature of the problem. If it is rectifiable, the surveyor usually makes recommendations, known as ‘conditions of class’. Maintenance of the yacht in class then becomes conditional on the work being carried out.

A yacht may be suspended from class if the owner does not request a survey following an accident causing damage or following repairs or alterations, and will be suspended automatically if any of the regular surveys are overlooked. Class will then be withdrawn altogether following a six-month suspension.

Details of suspensions and withdrawals, and the yachts concerned, are published on the internet for all to see, including insurers.

Legal recourse

Class surveyors have made serious mistakes in the past which have led to large claims. Societies are seen as having deep pockets and their liability cannot be limited by international convention in the same way that an owner’s can.

Where a society provides consultancy services going beyond its conventional remit, it would almost certainly be responsible for its mistakes, subject to the contract terms. However, the courts take a tender view of mistakes made when providing traditional classification services.

Claims against a class society may be an uphill struggle, for the following reasons:

• The primary legal responsibility for seaworthiness normally remains with the owner
• Societies may specify where a yacht may operate, but they do not specify how she should be operated
• The society may have expressly excluded liability where a contractual relationship exists
• Surveys tend to involve selected sampling, rather than stem-to-stern inspections, and
• A similarly high level of expertise is required to challenge their views. English courts have ruled out societies’ liability towards parties other than the owner. In 1985 a yacht called Morning Watch was sold with a valid classification certificate, but was so corroded that she was unseaworthy and worth considerably less than the buyer had paid. The buyer was unsuccessful in suing the society as the survey had not been requested by, or carried out for, the buyer, even though it had been undertaken with a purchase in mind. Societies could still be liable directly to an owner, however.

Although legal recourses against societies are limited, they have much to contribute to safety and can help maintain a yacht’s value

By contrast, some European courts take a less favourable view, with societies being found liable to third parties, although ‘gross negligence’ must have been displayed.

Where societies undertake work on behalf of flag states, they often benefit from their master’s state immunity. However, European Union legislation provides quality requirements where societies are working in this capacity, and this legislation does entertain the possibility of societies being made liable for gross negligence, but nothing less. Where an owner had failed to disclose something which a society would otherwise be anxious to survey, it is unlikely that the society would be exposed to any liability.

Although legal recourses against societies are limited, they have much to contribute to safety and can help maintain a yacht’s value. Classification should not, therefore, be seen as a pedantic exercise, performed just to keep insurers happy. The process brings to bear an independent and high level of expertise which should reassure present and prospective owners alike.

Understanding Yacht Classifications – Definitions, Explanations, and Regulations

Yacht classifications, also known as classification societies or class societies , are an important part of maritime safety. These classifications dictate the design, construction and ongoing maintenance of large commercial vessels and yachts.

The classifications provide highly detailed and technical standards that cover the yacht’s hull, its engines, and key safety systems.  The application of common safety requirements to personal vessels like yachts is something relatively new, so the procedures are constantly evolving. Typically, it is dependant on the service and the flag of the yacht.

Standard Yacht Types

Before discussing the different types of yacht classifications, it’s important to understand the different yacht types. Yachts are typically segmented based on the overall length and how many passengers they can accommodate. The standard yacht classification types are large yachts or luxury sailing yachts, commercial yachts, and private yachts.

Large Yachts

Large yachts, also known as luxury yachts, is the largest classification type for yachts. A large yacht has a load line length equal to or over 24m or about 80 feet. Just about every flag administrations have adopted safety codes for large yachts. Therefore, this is the only yacht definition having a universal meaning in the international regulatory framework of yachts.

Commercial Yachts

Commercial yachts are ones that are used for commercial use, whether it be sport or charter. These ships do not transport or carry any cargo and carry no more than 12 passengers.

All flag states require that commercial yachts are certified in accordance with a specific large yacht safety code. The most widely used safety code is the MCA Large Commercial Yacht Code (LY2) published in 2004.

Private Yachts

Private yachts are typical pleasure vessels used for the recreational and leisure purpose of its owner and his guests.  In some cases, they are also known as cruising yachts.

What Is A Classification Society?

Classification societies are organizations that set the rules that govern the construction, maintenance, and operation of yachts and vessels. Currently, there are 13 members of the International Association of Classification Societies . Classification societies were first started when insurance underwriters at Lloyd’s of London set standards for the ships that they would ensure.

As a result, Lloyd’s Register of Shipping (LR) was the original classification society. While many of the 13 members do not classify yachts, they cover everything from container ships to supertankers.

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

What Is A Flag State?

A vessel’s flag state is the jurisdiction or nationality under whose laws the vessel is registered or licensed. The flag state has the authority and responsibility to create regulations for vessels registered under its flag. These typically involve those relating to the inspection, certification, and issuance of safety and pollution prevention documents for a vessel.

Different flag administrations may perform inspections on the safety aspects of yachts using their own inspectors or use classification societies or other recognized organizations to perform these inspections.

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

What Is The Classification Process

The first step of classification involves the assessment of a yacht’s designs and regular inspections during the construction or conversion of a yacht. Once it is confirmed that all standards have been met, a certificate of classification is issued.

The certificate details the standards met, the intended use for the vessel, and whether the vessel should be used only in sheltered waters. The certificate is evidence that a yacht meets industry standards but isn’t necessarily a guarantee of seaworthiness.

Maintaining classification is achieved through regular surveys. These surveys, also known as ‘special’ surveys, typically take place every five years. These surveys assess things like the thickness of the hull, possible fractures, and other potential damage. They also consider the condition of electrical systems, machinery, and equipment.

Mandatory Classification Certificates

There are a variety of different classification certificates. The number and type of the mandatory certificates for a given ship will depend on its size.

International Tonnage Certificate This expresses the internal volumes of the yacht in gross tons. Unlike displacement tonnage, this does not quantify the weight of a vessel.

Large Yacht Code Certificate This certificate covers navigational and signaling equipment, life-saving appliances, fire protection, means of escape, and manning and crew accommodation.

Class Certificate This mainly deals with the yacht’s hull, machinery, electrical equipment, and outfitting.

International Load Line Certificate This certificate covers the weather-tightness of the yacht.

Safety Radio Certificate This certificate only applies if gross tonnage exceeds 300GT. It covers radio communication and distress installations.

MARPOL Annex I Certificate This certificate only applies if gross tonnage exceeds 400GT and covers the disposal of oil and bilge water.

MARPOL Annex IV Certificate This certificate only applies if gross tonnage exceeds 400GT or the yacht is certified to carry more than 15 people and covers the disposal of sewage from ships.

MARPOL Annex V This certificate covers the disposal of rubbish and applies to all ships.

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 cover machinery, electrical parts, life-saving and navigational equipment for yachts with a gross tonnage above 500GT.

International Safety Management Certificate This only applies to yachts with 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 only applies to yachts and ships with a gross tonnage greater than 500GT and covers the anti-piracy certification. A certified management company is requested to provide ashore assistance and establish onboard procedures and operational manuals.
