2.12.1 The total heel angle in still water due
to the effect of passenger movements or due to beam wind pressure
as per 1.1.4 of annex 6 shall
not exceed 10°. Passenger movement need not be considered where
passengers are required to be seated whenever the craft is operating
in the non-displacement mode.
2.12.2 In all loading conditions, the outward
heel due to turning shall not exceed 8°, and the total heel due
to beam wind pressure as per 1.1.4 of
annex 6 and due to turning shall not exceed 12° outward.
2.12.3 Demonstrating the effect of the passenger
heeling moment calculated as given by 2.10 above,
or a defined beam wind pressure when at speed, shall be established
by conducting a trial or model test with an equivalent heeling moment
applied by test weights. Passenger movement may only be neglected
on craft where the safety announcement (refer to 8.4.1 and 18.7) expressly requires passengers to remain seated throughout
the voyage.
