Q1. A vessel of SWATH (small waterplane area twin hull) design, has the following hydrostatic particulars when floating in water of density 1025 kg/m³:

Displacement = 1390 tonne

centre of buoyancy above the keel (KB) = 2.744 m

centre of gravity above the keel (KG) = 6.37 m

The distance between the centretines of each hull is 12 m and the half breadths of each hull, measured at equal intervals along the 72 m length of waterptane, are as shown in Table Q1.

Calculate the transverse metacentric height of the vessel in the above condition. (16)
