1. A mass of 75 kilogrammes should be assumed
per passenger except that this value may be reduced to not less than
60 kilogrammes where this can be justified. In addition, the mass
and distribution of the luggage should be to the satisfaction of the
Administration.
2. The height of the centre of gravity for passengers
should be assumed equal to:
-
(a) 1 metre above deck level for passengers standing
upright. Account may be taken, if necessary, of camber and sheer of
deck.
-
(b) 300 millimetres above the seat in respect
of seated passengers.
3. Passengers and luggage should be considered
to be in the space normally at their disposal.
4. Passengers should be considered as distributed
to produce the most unfavourable combination of passenger heeling
moment and/or initial metacentric height which may be obtained in
practice. In this connexion, it is anticipated that a value higher
than four persons per square metre will not be necessary.
