Q7. A. Explain how to distinguish between list and loll and describe how to return the ship to the upright in each case. (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:
Draught (m)
Displacement (t)
MCTI cm
(tm)
LCB from midships (m)
LCF from midships (m)
