International Standards

The International Standards Organisation (ISO) publishes standards on a vast range of subjects, including small craft (under 24m by ISO/TC188) and large yachts (over 24m by ISO/TC8/SC12). We represent the industry at each of these standards committees and the many working groups under the control of the principal committees. For an explanation of the standardisation process please see How are ISO standards developed.

The Technical Committee dedicated to small craft standards, ISO/TC188, was established over 25 years ago and develops standards for all aspects of small craft design and build, including equipment, systems, handling, stability and construction.

Many of the standards are developed in support of the Recreational Craft Directive (RCD) and when published provide boatbuilders with a means of demonstrating conformity with the RCD Essential Safety Requirements (ESR).

Standards are not the only means of demonstrating conformity – codes of practice, empirical design, previous service history or other suitable methods are acceptable equivalents. It is important to discuss such options with a Notified Body if relevant.

The Technical Committee for large yacht standards, ISO/TC8/SC12, was established in 2007 as a new committee to develop standards for boats over 24m length in support of current national and international codes for large yachts (superyachts), such as the Maritime and Coastguard Agency Large Yacht Code LY2. The work programme of this committee is developing with industry assistance, provided in the UK by British Marine Federation association Superyacht UK.

In the UK, standards work is carried out through the British Standards Institute (BSI), with shadow committees for each ISO Technical Committee. We provide industry representation at committees covering, in addition to small craft and large yachts, gas systems, lifejackets and marine electrical systems. Members support the Technical team as necessary on detailed topics such as steering systems, scantlings, fire protection and stability.

The principal committee for small craft is GME/33 Small Craft, constituting a broad cross-section of the marine industry, including the British Marine Federation, navigation authorities such as British Waterways, the Environment Agency, and the Broads Authority, user representative organisations such as Royal Yachting Association and the National Association of Boat Owners, classification societies such as American Bureau of Shipping and Lloyds Register and regulators such as the Maritime and Coastguard Agency.

Harmonised Standards

Standards developed for European Directives, such as the RCD, are mandated by the European standards body, European Committee for Standardization (CEN) and when published by CEN are known as harmonised standards.

All CEN standards are published and implemented in each of the EU member states as national standards. In the UK BSI publishes these standards as BS EN xxxxx where xxxxx is the number of the standard given by CEN. Essentially a harmonised standard is an agreement between all participating members stating that the standard is acceptable for use in all countries and meets the previous national requirements of each country.

Standards for small craft are developed by ISO/TC188 under an agreement whereby CEN adopts the published ISO standards and publishes as EN standards. For small craft standards, harmonised to the RCD, and published in the UK by BSI, the reference is therefore BS EN ISO xxxxx. A full list of RCD harmonised standards is available on the European Commission website .
