It is recommended that continuous hatchways may be treated
as a trunk in the freeboard computation provided regulation
36 is complied with in all respects.
The trunk deck stringer referred to in regulation
36(1)(b) may be fitted outboard of the trunk side bulkhead
in association with the following:
.1 The stringer so formed is to provide a clear
walkway of at least 450 mm in width on each side of the ship.
.2 The stringer is to be of solid plate efficiently
supported and stiffened.
.3 The stringer is to be as high above the freeboard
deck as practicable. In the freeboard calculation, the trunk height
is to be reduced by at least 600 mm or by the actual difference between
the top of the trunk and the stringer, whichever is greater.
.4 Hatch cover securing appliances are accessible
from the stringer or walkway.
.5 The breadth of the trunk is to be measured
between the trunk side bulkheads.
Regulation 36 is
complied with in all other respects.
