With particular regard to the length of raised quarter deck
in paragraphs (3) and (4) of this Regulation,
the following interpretation applies:
In a ship with a superstructure which extends over the whole
length of the freeboard deck, the part of the superstructure from
the after perpendicular up to a maximum of 0.6L may be
treated as a raised quarter-deck. In this respect, if no watertight
front bulkhead is fitted the bow may be considered to act as such.
The length limit imposed by paragraph
(4) of this regulation for a raised quarter-deck of less than
standard height applies to the length calculated as indicated in paragraph (3) of this Regulation.
