1 In general, the periphery of the craft is considered
to only be the surface of the shell encompassed by the outboard surface
of the outermost hull at any given section, if considering a multihull.
2 Since damage to the "periphery" at the forward
and aft ends of blunt-ended craft are not adequately covered by consideration
of side damage using the above general interpretation of "periphery",
the following assumed extents of damage should be applied in such
cases as illustrated in figure
2.6.7d:
-
.1 at the fore end, damage to the area defined
as Abow in 4.4.1, the aft limit of which being a transverse
vertical plane, provided that this area need not extend further aft
from the forward extremity of the craft's watertight envelope than
the distance defined in 2.6.7.1; and
-
.2 at the aft end, damage to the area aft of a
transverse vertical plane at a distance 0.2∇⅓ forward
of the aft extremity of the watertight envelope of the hull.
3 The provisions of 2.6.6 in relation to damage
of lesser extent remain applicable to such damage.
