For vessels operating in areas where ice accretion is likely
to occur:
-
.1 no shutters should be fitted in the freeing
ports;
-
.2 with regard to operational precautions against
capsizing, reference is made to the recommendations for skippers of
fishing vessels on ensuring a vessel's endurance in conditions of
ice formation, as given in paragraph 5.3.3 and
in annex 2.
