21B.9.1 Mess rooms should be located apart from
the sleeping rooms to avoid disturbing those persons sleeping and
as close as practicable to the galley. Mess rooms should be of adequate
comfort and properly furnished and equipped (including ongoing facilities
for refreshment), taking account of the number of seafarers likely
to use them at any one time. Mess rooms for seafarers who are officers
and other seafarers may be separate or common, as appropriate.
21B.9.2 Where the substantially equivalent arrangements
in 21B.8.3 and 21B.8.4 are used, the floor area of mess rooms for
seafarers should not be less than 1.5 square metres per person of
the planned seating capacity.
