ISO 11592-1:2016 specifies the requirements for determination of the maximum propulsion power rating and manoeuvring speed for engine-driven small craft with a length of hull (L_H) of less than 8 m (L_h according to ISO 8666).

It is not applicable to the following:

personal water craft as defined by ISO 13590;[6]

canoes and kayaks;

inflatable boats, as defined by ISO 6185-1, ISO 6185-2, ISO 6185-3, and ISO 6185-4, 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 to this part of ISO 11592;

racing boats: craft designed and constructed solely for competitive racing.

ISO 11592-1:2016 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.
