Q14. A ship of length 120m displaces 10650 tonne when floating at a draught of 7.2 m in sea water of density 1025 kgm³. The waterplane area is defined by half breadth as given in table.

When a mass of 10 tonne is moved a distance of 16 m across the deck, a deflection of 40mm is recorded on a pendulum of 8 m length.

The height of the centre of buoyancy above the keel (KB) may be determined suing morrish’s formula as given below.

Calculate the KG of the ship in the above condition.
