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.

4 General requirements
4.1 The maximum propulsion power rating shall be derived using the results of the tests specified in
Clause 6 and Clause 7. These tests shall be used for determining the maximum manoeuvring speed.
4.2 Craft fitted with steering means other than a steering wheel shall pass the avoidance line test
specified in Clause 7.
4.3 Craft fitted with a steering wheel shall pass the quick turn test specified in Clause 6.

4.4 The craft shall pass the tests at no less than 85 % of maximum craft speed (v ) or the maximum
max
test speed limit (v ), whichever is the lower, with the most powerful engine recommended by the
t max
craft manufacturer.
v shall not be more than 70 knots.
t max
4.5 The craft shall be equipped with a warning label in accordance with Clause 9, and provide
information in the owner´s manual in accordance with Clause 10, if:

max max,
b) v ≥ v and the craft passes the avoidance line test and/or the quick turn test at 100 % v .
max t max t max
Additionally, craft requiring a warning label shall have a speed measuring device visible from the helm
station(s).
4.6 If the maximum manoeuvring speed is less than required in 4.4, the craft manufacturer shall
change the installed engine(s) to an engine(s) giving a lower power output, or modify the craft in order
to comply with 4.4.
5 Test procedures
5.1 Purpose of the tests
Determination of maximum manoeuvring speed at which the craft complies with the avoidance line
test and/or the quick turn test.
5.2 Craft preparation
5.2.1 The craft shall be in the performance test mass condition (m ), as defined in ISO 8666, rigged
p
with equipment for safe operation of craft, engine and operator.
5.2.2 The maximum craft speed, v , shall be determined by no less than two timed passages over
max
a measured distance in both directions, or by any other suitable and accepted means of craft speed
measurement accurate within one knot of true craft speed.
5.2.3 The craft shall be equipped with engine(s) giving the maximum engine power recommended by
the craft manufacturer (see 4.4 and 4.6).
5.2.4 Equipment shall be installed in accordance with the equipment manufacturer’s recommendations.
5.2.5 During the test, the speed should be measured with an accuracy of ± one knot.
5.2.6 A steering system with the lowest ratio (quickest turn) offered on the craft model shall be
installed. For propeller-driven craft, the craft manufacturers’ or the engine manufacturer's recommended
propeller shall be mounted. If different propellers are offered, the propeller providing maximum craft
speed shall be used.
5.2.7 If the maximum engine power can be met with a single or multiple engines, the craft shall be
tested with the configuration giving the maximum spee
