ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non­governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

the European Committee for Standardization (CEN) Technical Committee CEN/TC 464, Small craft, in

accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

the addition of Clause 2, Normative references, and the renumbering of the remaining clauses; all

This document establishes definitions of main dimensions and related data and of mass specifications

and loading conditions. It applies to small craft having a length of the hull (L ) of up to 24 m.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

intersection line of the water’s surface with the craft’s hull when the craft (3.15) is afloat

waterline (3.1) of the craft (3.15) when upright in the maximum loaded displacement (3.6)

intersection between deck and hull, for rounded deck edges the natural intersection, or, where no deck

is fitted or the hull extends above the deck (bulwark), the upper edge of the craft's hull

Note 1 to entry: The upper position of the sheerline depends on the inclination between the hull/deck intersection

maximum width of the hull at the transom at or below the sheerline (3.3), excluding extensions, handles

Note 1 to entry: Where spray rails act as chines or part of the planing surface, they are included in the transom

Note 2 to entry: For craft (3.15) with a rounded or pointed stern or with a transom beam of less than half the

maximum beam of the craft, the transom beam, B , is the widest beam at or below the sheerline at the aft quarter

mass of water displaced by the craft (3.15), including all appendages, when in the fully loaded ready-

volume of water displaced by the craft (3.15) that corresponds to the displacement (3.5)

Note 1 to entry: Where the density of water used to calculate the volume of displacement is not salt water at a

density of 1 025 kg/m , the density of water used to calculate the volume of displacement is specified.

recreational boat, and other watercraft using similar equipment, of up to 24 m length of hull (L )

Measurements shall be established with the craft at rest at the maximum load waterline/reference

The lengths of a craft shall be measured parallel to the maximum load waterline/reference waterline

and craft centreline as the distance between two vertical planes, perpendicular to the centreplane of

The maximum length (L ) shall be measured in accordance with 5.2.1, one plane tangent through the

This length includes all structural and integral parts of the craft, such as stems or sterns, bulwarks, and

This length includes parts which are normally fixed, such as fixed spars, bowsprits, pulpits at either

end of the craft, stemhead fittings, rudders, outboard motor brackets, outdrives, waterjets, and any

propulsion units extending beyond the transom, diving and boarding platforms, rubbing strakes, and

Outdrives, waterjets, other propulsion units, and all movable parts shall be measured in their normal

operating condition to their maximum lengthwise extension when the craft is underway.

The length of the hull (L ) shall be measured in accordance with 5.2.1, one plane passing through the

foremost part of the craft and the other through the aftermost part of the craft.

This length includes all structural and integral parts of the craft, such as stems or sterns, bulwarks, and

This length excludes removable parts that can be detached in a non-destructive manner and without

affecting the structural integrity of the craft, e.g. spars, bowsprits, pulpits at either end of the craft,

stemhead fittings, rudders, outdrives, outboard motors and their mounting brackets and plates, diving

platforms, boarding platforms, rubbing strakes, and fenders if they do not act as hydrostatic support

With multihull craft, the length of each hull shall be measured individually. The length of the hull, L ,

The waterline length (L ) for a designated load condition and its corresponding design trim shall be

measured in accordance with 5.2.1, one plane passing through the foremost intersection of the stem with

the flotation plane and the other through the aftermost intersection of the hull and the flotation plane.
