6.1 A vessel shall undergo a simplified stability
proof test in accordance with regulation III/8 in the
presence of an Administration surveyor.
6.2 A simplified stability proof test in accordance
with regulation III/8 is conducted to determine where
a vessel, as built and operated, has a minimum level of initial stability.
Failure of the simplified test does not necessarily mean that the
vessel lacks stability for the intended operating area, service, and
operating condition, but that calculations or other methods shall
be used to evaluate the stability of the vessel.
6.3 The stability of a vessel certified to operate
in exposed waters shall be determined by calculation to the satisfaction
of the Administration.
