Q7. a) Describe briefly the significance of the factor of sub-division; (6)

b) A ship 120m long has a light displacement of 4000 tonne and LCG in this condition 2.5m aft of midships.  (10)

The following items are then added:

Cargo    10000 tonne      LCG 3.0 m           forward of midships

Fuel       1500 tonne        LCG 2.0 m           aft of midships

Water     400 tonne          LCG 8.0 m           aft of midships

Stores    100 tonne           LCG 10.0m         forward of midships

Using the following hydrostatic data, calculate the final draughts:
