Convention on Load Lines, 1966, applies should comply with regulation 18 of this Convention.
6.6.2
footnote
In decked fishing
vessels of 12 m and over where it is essential for fishing operations,
flush deck scuttles of the screw, bayonet or equivalent type and manholes
may be fitted provided these are capable of being closed watertight
and such devices should be permanently attached to the adjacent structure.
Having regard to the size and disposition of the openings and the
design of the closing devices, metal-to-metal closures may be fitted
if they are effectively watertight. Openings other than hatchways,
machinery space openings, manholes and flush scuttles in the working
or superstructure deck should be protected by enclosed structures
fitted with weathertight doors or their equivalent. Companionways
should be situated as close as practicable to the centreline of the
vessel.footnote
