5.3 Tests to be applied
Non-sailing boats shall be assessed using clause 6.
Sailing boats other than habitable multihulls shall be assessed using clause 7. Habitable multihull sailing boats
shall be assessed using ISO 12217-2.
If a sailing boat can also be used as a non-sailing boat, e.g. for rowing or for engine propulsion, it shall also meet
the requirements for non-sailing boats. The design category finally given is that for which the boat satisfies all the
relevant requirements.
5.4 Alternatives
If the boat does not reach the desired design category, modify the maximum load and/or the number of crew and
repeat the assessment.
Boats which are fully decked may alternatively be assessed using ISO 12217-1 or ISO 12217-2, for non-sailing and
sailing boats respectively, in which case they may be able to attain design categories A or B.
6 Tests to be applied to non-sailing boats
6.1 General
Non-sailing boats may be assessed by any one of six options according to length of hull, amount of flotation and
decking, and whether the boat is fitted with suitable recesses complying with ISO 11812. These options and the
corresponding tests to be applied are given in Table 3.
The design category finally given in respect of stability and buoyancy is that for which the boat satisfies all the
relevant requirements.

d This test is not required to be applied if, when swamped during the test described in 6.4, the boat supports an equivalent dry mass of
133 % of the maximum total load, or if the boat does not take on water when heeled to 90O from the upright in light craft condition.
