Yacht owners guide to Classification Societies

Alysia was built specifically for charter and complies to SOLAS. She can carry up to 36 passengers and is over 500GT.

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.

Lloyd's is only one of the classification societies who carry out surveys on superyachts.

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.

Suing a classification society is extremely difficult, due to their secretive nature and complex legal agreements they make with clients.

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.
