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.

yacht classification

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.

yacht classification

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.

yacht classification

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.

Ensuring comfort, safety and sustainability

Yacht owners, charterers and passengers increasingly expect both top-notch comfort and green credentials from their yacht or from the commercial vessel they charter. While luxury remains at the core of the yacht business, ship owners, operators and charterers must meet port requirements and national regulations for limited emissions.  Bureau Veritas offers key technical, regulatory and environmental expertise to enable yachts to continue sailing in protected areas while maintaining high levels of luxury and comfort. Our notations, digital tools, global network, and expertise with super and mega yachts provide a safe and eco-friendly onboard experience.

Enabling regulatory compliance

ENABLING REGULATORY COMPLIANCE for yachts

It is crucial for yachts to comply with safety and technical regulations for ship design, structure and maintenance. Bureau Veritas’ NR 500 Rules for the classification and certification of yachts under 100 meters [1] outline detailed requirements for building materials, hull structure, machinery, automation and more. Find out more about our Rules & Notations for Yachts

[1] Larger yachts must follow class rules for sea-going vessels, and according to the chosen Flag specific yacht codes, for example the Red Ensign Yacht Code.

Improving ship sustainability

IMPROVING SHIP SUSTAINABILITY for Yachts

To meet changing social and regulatory expectations, yacht owners are increasingly exploring greener shipbuilding and operating practices. Bureau Veritas’ Green notation verifies that yachts have been optimized for energy efficiency, assessing fuel consumption, ship super structure and hull design. Yachts that currently limit their emissions by using hybrid electric power can also earn a Hybrid notation. Those designed to someday use hybrid electric power can earn a Hybrid-Prepared notation

Energy storage systems (ESS) are also an option for yacht owners to reduce emissions while in port and when operating in sensible eco-areas. Those systems also help reduce fuel consumption. Our rules, notations and technical expertise ensure for safe and efficient ESS design and installation. Although our current fuel cell guidelines apply to commercial shipping, Bureau Veritas’ experience in this technology may be of use to owners and yards exploring greener means of energy production and propulsion.

Increasing onboard comfort and wellbeing

INCREASING ONBOARD COMFORT AND WELLBEING for yachts

Comfort is a non-negotiable element for yacht owners and passengers, and this means ensuring limited onboard noise and vibrations. Yachts can earn Bureau Veritas’ Comfort notation by undergoing an assessment of sources of noise and vibration, such as engines and propellers. Owners and yards can then take measures to improve ship structure and design, reducing noise and increasing comfort.  Bureau Veritas has also partnered with owners and operators to establish better bio-risk management. This includes outbreak management plans, embarkation and debarkation plans, protective measures and other health best practices to safeguard the wellbeing of all passengers and crew.

Digital tools for yachts

Digitalization is changing how ship owners expect their vessels to be designed, built, assessed and classed. Bureau Veritas offers a range of digital tools to help yacht owners quickly and accurately conduct classification, assess safety and manage their fleets. These include Veristar Project Management , Digital Classification and remote surveys , and our ComposeIT and StarBoat structural assessment tools. Increased digitalization naturally increases cyber security concerns. Bureau Veritas’ CYBER SECURE notation helps owners comply with IMO legislation (Resolution MSC.428 (98)).

Yacht Classifications

  • By Dudley Dawson

yacht classification

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.

Understanding the Classification of Yachts A, B, C and D

Understanding the Classification of Yachts A, B, C and D:

  Since 1998, Europe (EEC) classifies yachts according to 4 categories A or B or C or D and this is a law. In order to sell a boat in the large territory of the EEC, it must be classified with a plate that mentions its classification and it must be clearly visible inside the boat, usually near the helm.

yacht classification

At first glance, it sounds very good when you hear class A, but what is it really, what are the differences, is it necessary to acquire a class A…

The brokers at ItaYachtsCanada have written an article on this subject in the past ( click here ), but here are the important characteristics to know about the subject.

The classification allows you to know in which kind of sea intensity you can safely venture, that is to say, taking into account the wind and the wave height in reference to the Beaufort index.

(At the end of this text, there is an explanation of the classes according to the Beaufort index).

Let’s say we focus on class A and B, on the major differences.

First of all, the differences are not very visible to the naked eye or it takes a trained eye to see them.

Depending on the type of water you plan to sail and if the weather guides you on each trip, a B class is also a very good choice.

Of course, you must have all the required safety equipment on board.

Ideally, a boater should always sail in rather peaceful conditions, taking into account the weather first. We always say that boating is fun, so stay away from difficult sailing situations. (Ideally, always with a Beaufort index of 6 and less, ideally a Beaufort index of 4 and less).

Many manufacturers have retained the parameters of the B class to build their boats, mainly for reasons of production costs and that boaters in general do not care much about these characteristics.

The problem is how to differentiate between the vast range of B class boats, how to distinguish those that are closer to an A class (B +) from those that are built as (B -).

How to find your way around, especially for a layman…

yacht classification

It is important to know that some manufacturers build their boats with an A approach, but without respecting all the mandatory specifications to be classified A.

Here are some guidelines to quickly see if the manufacturer has done things right.

– Inspect the portholes and closing mechanisms (Plastic or Metal)

– The presence of numerous drains to evacuate water (at the fly and cockpit), it is essential to be able to evacuate any water accumulation quickly.

– Height of the freeboard.

– Engine access hatch, well insulated and secured for water leaks.

– Bilge pumps (number, size and capacity)

– Mechanism to pump water from the engine room massively (e.g. possibility to use the engine water pumps with a joystick)

– The center of gravity of the boat is well balanced (rather low).

Hull joints, a very low center of gravity, excellent weight distribution, electrical system (24 V), are also part of the certification criteria especially for A boats, but difficult to assess for a yachtsman.  It is possible, but in a summary way.

The CE classification allows to differentiate yachts according to certain criteria present, we are talking mainly about structural strength, integrity of essential parts of the hull, reliability of propulsion, steering systems, power generation and all other features installed on board to help ensure the essential services of the yacht.

Therefore, it is important to understand that a Class A yacht is built to a much higher standard than a Class B. This is not reflected in the luxurious appearance of the boat.

What you have to remember is that the major enemy for a boat, besides a fire, is water infiltration on board which can destabilize the behavior of the boat, cause a stop of the engines, major electrical problems, in short which can quickly put the boat out of use and/or out of control.

A classification body such as RINA (see list at the end of this text) has been checking the activities of builders and classifying yachts for over 20 years.

If the boat is sold in the European Community, the classification is mandatory and must be visible near the cockpit. This same classification is not present when the boat is intended for North America or very rarely.

Do not hesitate to contact a professional broker, he will be able to guide you according to your needs, your criteria and especially the places of navigation.

yacht classification

As the CE classification is not always displayed when the boat is destined for the North American market, here are some references on this subject based on the most recent data available (subject to change without notice):

P.S. Let’s mention that as a general rule yachts over 80 ft are Class A, but according to the rules in place, the classification is no longer mandatory or mentioned beyond 79 ft.

Class A (yachts over 50 ft):

BEST KNOWN MODELS :

Ferretti 500, 550, 670 and up

Pershing : 7X and up

Azimut 62, 64, 66, 68 Fly and up

Azimut S8 and up

Azimut Magellano : the whole range

Sunseeker Sport yacht 65, Yacht 88 and up

Princess yacht 80 and up (TBC)

Marquis Yachts (no longer in production)

Montecarlo MCY 66 and up

Searay L650

Class B (yachts over 50 ft):

Sunnseeker 52 fly, 55 fly , 66 fly, 68 fly, Sport Yacht 74, 76 Yacht

Azimut 50 fly, 55 fly, 60 fly, S6 and all Atlantis

Princess : all yachts under 70 ft

Princess Y72, Y78 and less

Ferretti 580 fly

All Absolute

All Fairline

All Beneteau & Jeanneau & Monte Carlo 52

All Searay except L650.

All Cruisers Yachts

For more information, here is an article published by the brokers at ItaYachtsCanada, click here .

There is also the dry weight which can help determine a quality yacht.

Don’t hesitate to compare yachts of the same size based on dry weight, you may be surprised.

For example, a 52′ yacht that weighs 30,000 lbs empty compared to another one that weighs 60,000 lbs empty, ask yourself some questions.

But be careful, it is more and more difficult to get the manufacturers’ empty weights. They have understood the importance of being rather vague on the subject or of making comparisons more difficult. Indeed, we are talking about LIGHT WEIGHT, which is difficult to measure.

The manufacturer who has confidence in thier boat will have no difficulty in giving a total warranty of at least 12 months, 24 and even 36 months.  Please note the  difference here between the manufacturer’s warranty and the dealer’s warranty .

Many European manufacturers sell their boats to dealers in America without a warranty. This means that the dealer assumes the full 12-month warranty out of his profit from the sale. The engine manufacturer, on the other hand, honors its own warranty such as Volvo, Cummins, Caterpillar, MAN, MTU, Yanmar. For other major components, it will be up to you to take the necessary steps to have the warranty honored, such as for the generator, the air conditioning, the thrusters, etc…

Therefore, acquiring a boat requires a much more specialized expertise than that of a car! Contact ITA Yachts Canada Inc. to speak with a professional and independent broker with experience in the following markets (Canada, United States and Europe whether the boat is new or used).

MORE INFORMATION.

Here is some more information about the classification, what the law in Europe says about it.

Here are some links to help you understand the Beaufort index in direct relation with the classification of yachts sold on the territory of the EEC:

Click here for the TRANSPORT CANADA website

Click here for an article on Wikipedia (more descriptive with photo).

According to the EEC rules, here is the description:

The classification of vessels marked “CE

CE marked vessels are classified into four design categories according to their ability to cope with sea conditions characterized by wind speed and significant wave height. Depending on the type of navigation practiced, the boater must choose a vessel whose design category authorizes such practice.

– Design Category A: Recreational vessels designed for winds that can exceed force 8 (on the Beaufort scale) and for waves that can exceed a significant height of 4 meters, excluding exceptional conditions such as storms, severe storms, tornadoes and extreme sea conditions or huge waves (these conditions exclude force 10 and following).

– Design Category B: Pleasure craft designed for winds up to and including force 8 and for waves up to and including 4 meters in significant height.

– Design Category C: Pleasure craft designed for winds up to and including force 6 and for waves up to and including two meters in significant height.

– Design Category D: Pleasure craft designed for winds up to and including force 4 and for waves up to and including 0.30 meters, with occasional waves up to and including 0.50 meters.

yacht classification

Vessels in each of these design categories shall be designed and constructed to withstand the parameters of each of these categories, with respect to buoyancy, stability and other relevant requirements, and to have good maneuverability characteristics.

The known classification bodies for the EEC:

RINA (Registro Italiano Navale),

BV (Bureau Veritas),

DNV (Det Norske Veritas),

Germanischer Lloyd,

LR (Lloyd’s Register).

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.

A BRIEF ON KINDS OF YACHTS

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).

Sailboats

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.

Multihull

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.

Understanding Yacht Classifications – Definitions, Explanations, and Regulations

yacht classification

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.

CE Yacht Compliance Classification

29 March 2016

The CE Yacht Compliance Classification System is the European (CE stands for “ Conformité Européenne ” in French) dictating the standards for CE Certification for construction and sale of boats . Vessels in one of the categories of controlled products cannot be legally sold in the EU unless they have passed the tests to receive the CE Certification. This regulation applies to all yachts for sale and recreational craft from 2.5 to 24 meters, whether they are intended for navigation at sea or in inland waters. New or used boats coming from countries other than the Member States of the European Union are also subject to CE marking.

In 1994, the countries in the European Union adopted the Recreational Craft Directive (RCD), which they amended in 2003. This constitutes a single set of “harmonized” essential requirements for boats sold in any member country.

The compliance with the RCD is required by law in the European Union member countries, and third-party classification societies inspections and their certifications are required as part of the process of CE yacht compliance classification. Boats are given a CE certification at the end of the process, which confirms that they have passed and comply with the technical, construction, safety and legal requirements making them legally valid for sale in the European Union. In Europe, we call them commonly “CE compliant boats” .

CE certification required

Summary of the origin and CE yacht compliant classification and how certification works.

Since 1998, European legislation indicates that pleasure boats must carry the CE certification (or mark), requiring them to meet certain construction and safety standards. For this, the boats are classified into four categories according to their design and skills to face different sailing conditions depending on the wind force and wave height.

Knowing that the weather is a variable phenomenon, these categories are not intended to limit the distance boaters can sail away (this depends on onboard safety equipment), but rather to responsibly inform them about the capabilities of their boat to safely navigate based on the offshore weather conditions. For each vessel, the design category is characterized by a letter between A and D.

BEAUFORT scale

First, let’s start with the BEAUFORT scale. This scale gives you the status of the sea in order to plan your trips. It was the British admiral Francis BEAUFORT who imagined a scale with sufficiently precise criteria to quantify the wind at sea and allow the divulgation of reliable information universally understood. This scale consists of 13 degrees, from 0 to 12, which is remarkable in this scale is that it can assess the effect of wind on the surface of the sea.

We will focus on the scale with the forces of 6, 7 and 8 to our need for explanations. There is indeed a direct link between the Beaufort scale and the certification of yachts (see photo above of the scale to better understand the graduation of wind forces).

  • CE CLASS A yachts are designed for large sea voyages (everywhere), in which wind force may exceed 8 on the scale of BEAUFORT and waves can also exceed a significant height of 4 meters. These yachts are designed largely to be self-sufficient in this rather hostile environment. CAREFUL, in most cases, this is only theoretical.
  • CE CLASS B yachts are designed to travel off the coast (200 miles or less) in which the winds can be up to force 8 (not exceeding) and waves can reach a height up to 4 meters (not exceeding).
  • CE CLASS C boats are designed for travel close to the coasts and in large bays, estuaries, lakes and rivers in which winds can be up to force 6 (not exceeding) and waves may reach a height of 2 meters (not exceeding).
  • CE CLASS D boats are designed for cruises in protected waters, like small lakes, rivers and canals in which the winds can be up to force 4 and waves can reach a height up to 0.30 meter (less than 1 foot).

Rules of CE certification

The rules of CE certification for construction and sale of boats are designed to assess the structural strength and integrity of essential parts of the hull, the reliability, and function of propulsion, steering systems, power generation and all other features installed on board to help ensure the key essential services of the yacht.

You understand therefore that a CLASS A yacht respects a much more rigorous construction protocol than a CLASS B yacht and so on… Of course, it is strictly advised not to sail past a force 6 for pleasure yachting and no matter the class A or B. This is a matter of safety, comfort and pleasure being always present in your cruise.

To ensure recreational boating, always check the weather before each ride at sea and especially verify any potential changes every hour. In addition, you must always carry the safety equipment onboard depending on the type of navigation that you practice and the laws and regulations in the countries where you cruise, and feel free to be overcautious.

It is obvious that in case of bad weather, for example, it is better to find yourself onboard a CLASS A yacht, which will necessarily have a better safety margin, regardless of sea conditions… Before buying a new or pre-owned boat , always ask for the classification of your future yacht, this document is required for the new registration (in Europe).

A CE-Type Certificate (or homologation) is generally issued for production vessels manufactured in series by different shipyards , particularly European.

There are several classification societies capable of achieving the CE classification for construction and sale of boats , the main ones are RINA (Registro Italiano Navale), BV (Bureau Veritas), DNV (Det Norske Veritas), Germanischer Lloyd, LR (Lloyd’s Register).

Other societies and certifications

There are also other classification societies for vessels built or sold outside the EU such as ABS (American Bureau of Shipping) and NK (Nippon Kaiji). There are also other types of certifications such as the MCA (UK – Maritime and Coastguard Agency), which however is not a classification organization. We will write more articles on commercial classifications later.
