Foreword
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 non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
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
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 188, Small craft.
This second edition cancels and replaces the first edition (ISO 8666:2002), which has been technically
revised with the following main changes:
— definitions 2.7 to 2.13 have been added;
— list of symbols in Table 1 has been extended;
— 4.3.5 and 4.3.6 have been added;
— 4.5.2, 4.5.3 and 4.5.4 have been added, and “projected sail area” has been deleted;
— 6.4 to 6.8 have been added;
— 7.1 has been modified and 7.3 added;
— clause on owner’s manual has been deleted.

2.10
reference sail area
A
S
actual profile area of sails set abaft a mast, plus the maximum profile areas of all masts, plus reference
triangle area(s) forward of each mast

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

4.2 Longitudinal
4.2.1 General
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 craft.
4.2.2 Maximum length, L
max
The maximum length (L ) shall be measured in accordance with 4.2.1, one plane tangent through the
max
foremost part 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
hull/deck joints.
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
permanent fenders.

operating condition to their maximum lengthwise extension when the craft is underway.
This length excludes the following:
— outboard motors;
— any other type of equipment that can be detached without the use of tools.
