Some Administrations accept that timber freeboards may be
assigned to ships with reduced type 'B' freeboards, provided the timber
freeboards are calculated on the basis of the ordinary type 'B' freeboard.
Regulation 45(2) and (3) should
be interpreted such that the Timber Winter mark and/or the Timber
Winter North Atlantic mark are placed at the same level as the reduced
type 'B' Winter mark when the computed Timber Winter mark and/or the
computed Timber Winter North Atlantic mark fall below the reduced
type 'B' Winter mark.
