1 When calculating the bow height, the sheer of
the forecastle deck may be taken into account, even if the length
of the forecastle is less than 0.15L, but greater than
0.07L, provided that the forecastle height is not less
than one half of standard height of superstructure as defined in regulation 33 between 0.07L and
the forward terminal.
2 Where the forecastle height is less than one
half of standard height of superstructure, as defined in regulation 33, the credit bow height may be
determined as follows:
-
.1 when the freeboard deck has sheer extending
from abaft 0.15L, by a parabolic curve having its origin
at 0.15L abaft the forward terminal at a height equal
to the midship depth of the ship, extended through the point of intersection
of forecastle bulkhead and deck, and up to a point at the forward
terminal not higher than the level of the forecastle deck. However,
if the value of the height denoted h
t in figure 9 is smaller than the value of the
height denoted h
b, then h
t may
be replaced by h
b in the available bow height
(figure 9).
-
.2 when the freeboard deck has sheer extending
for less than 0.15L or has no sheer, by a line from the
forecastle deck at side at 0.07L extended parallel to
the base line to the forward terminal (figure
10).
