3.1 The program
is to be capable of calculating and printing, for each loading condition,
the list of deadweight items and their corresponding centres of gravity,
displacement, final VCG, LCG, draughts, trim, GM, free surface correction
and, where available, TCG. It should be noted that the method adopted
by the program to calculate the free surface correction should be
the same as that shown in the approved stability booklet.
3.2 The following
will also be assessed:
- Residual GZ distribution, in curvilinear form, showing compliance
or otherwise with intact stability criteria.
- Angle of downflooding.
- Limiting KG/GM value showing compliance or otherwise with intact
stability criteria.
3.3 The program
should take account of any initial angles of heel when carrying out
stability calculations.
3.4 The program
should also be capable of taking account of wind, icing and water
absorption in timber when carried on deck.
