Q2. (a) Sketch and clearly label a statical stability curve for a vessel with its centre of gravity on the centretine but having a negative metacentric height when in the upright condition.  (3)

(b) The ordinates for part of a statical stability curve for a bulk carrier at a displacement of 18000 tonne are given in Table Q2.

The ship has a hold 40 m long and 30 m wide which contains bulk grain towed at a stowage rate of 1.25 m3/tonne.

During a heavy roll, the grain shifts so that the level surface is lowered by 1.5 m on one side and raised by 1.5 m on the other side.

(i) Plot the amended statical stability curve for the ship. (12)

(ii) Determine the angle of list due to the cargo shift, from the curve. (1)
