Calculating the effect of free surface of liquids (FSE) 203
ballast. Find the moment of statical stability when the ship is heeled 5
degrees.
8 A box-shaped vessel has the following data.
Length is 80 m, breadth is 12 m, draft even keel is 6 m, KG is 4.62 m.
A double bottom tank 10 m long, of full width and 2.4 m depth is then half-®lled with water ballast having a density of 1.025 t/m3. The tank is located at amidships.
Calculate the new even keel draft and the new transverse GM after this water ballast has been put in the double bottom tank.
