This International Standard establishes the requirements for determination of the maximum propulsion power rating for engine-driven small craft with a length of hull of less than 8 m.
This International Standard is not applicable to:
- personal water craft as defined by ISO 13590;
- canoes and kayaks;
- inflatable boats, as defined by parts 1 to 3 of ISO 6185, except that ISO 6185-3 requires rigid inflatable boats (RIBS) capable of a maximum speed of 30 kn or more to be tested in accordance with ISO 11592;
- racing boats: craft designed and constructed solely for competitive racing.
This International Standard does not specify craft constructional strength requirements related to maximum rated power and does not guarantee security from instability under all conditions of seaway, wind, wakes and waves.
