 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.
