(1) Except as provided for in paragraph (2) of
this Regulation, the effective length (E) of an enclosed superstructure
of standard height shall be its length.
(2) In all cases where an enclosed superstructure
of standard height is set in from the sides of the ship as permitted
in Regulation 3 (10), the effective length shall be the length modified
by the ratio of b/Bs, where
|
b |
= |
is the breadth of the superstructure
at the middle of its length; and |
|
Bs |
= |
is the breadth of the ship at the
middle of the length of the superstructure. |
Where a superstructure is set in for a part of its length, this
modification shall be applied only to the set in part.
(3) Where the height of an enclosed superstructure
is less than the standard height, the effective length shall be its
length reduced in the ratio of the actual height to the standard height.
Where the height exceeds the standard, no increase shall be made to
the effective length of the superstructure.
(4) The effective length of a raised quarter deck,
if fitted with an intact front bulkhead, shall be its length up to
a maximum of 0.6 L. Where the bulkhead is not intact, the raised quarter
deck shall be treated as a poop of less than standard height.
(5) Superstructures which are not enclosed shall
have no effective length.
