resistance to waves and wind heel due to wind action
Table 3— Static Stability compliances Type VII
C and D 6.2
Not applicable 6.4a
a The application of 6.4 is only required for boats where ALV ≥ 0,5 LWL BH
The offset load test shall be conducted with centre-of-gravity of the seated crew positioned 0,1m above the top of the buoyancy tube and on the vertical tangent to the inboard face of the buoyancy tube as shown in Figure 2.
In conducting the offset load test, because the boat cannot sink if it complies with 7.4 below, the test does not have to be limited by the freeboard margin to water flooding over the buoyancy tube into the interior of the boat.

7.3.2 Instead of the requirements of 7.3.1, alternatively the stability and freeboard may be assessed using one of the following
a) options 1 or 2 of ISO 12217-1:2013 for boats with LH greater than or equal to 6m, in which case all the requirements of the chosen option shall be applied, but 7.4.3 and 8.7 of this standard shall not apply; or
b) option 2 of ISO 12217-3:2013 for boats with LH less than 6m, in which case all the requirements of the chosen option shall be applied, but 7.4.3 of this standard shall not apply.
