4.1 In accordance with paragraph 4.4, cargo density
is determined by dividing the total deadweight at the summer load
line draft by the total cargo volume. It is recognized that loading
the vessel with maximum cargo and no consumables may result in trim
of the vessel. However, for the purposes of this regulation calculations
should be carried out based on a hypothetical condition with zero
trim and zero heel. The use of a hypothetical condition rather than
actual load cases was adopted in order to insure uniform application
of this regulation.
