Q4. A ship of length 180 m, floats at its load draught with a displacement of 50000 tonne in sea water of density 1025 kg/m³. The longitudinal center of buoyancy (LCB) is 1.80 m aft of midships.

In this condition, the forward half of the ship displaces 23000 tonne and has a center of displaced volume (LCB) 33.0 m forward of midships. This part of the ship is to be replaced with a new forward half of similar length, but having new immersed cross section areas, to the same load draught, as given in Table Q1.

Calculate EACH of the following, for the new condition:

(a) The displacement of the ship;

(b) The longitudinal position of the ship’s center of buoyancy.
