WebThe displacements will be different but the volumes of displacement will be the same. If a ship is floating at a draught in FW, to find the equivalent SW displacement for the same draught: DISPL SW = DISPL FW x 1.025. Therefore, for the ship shown: DISPL FW x 1.025 = DISPL FW + (WPA x FWA x 1.000 t/m3) Where, FWA is expressed in meters.
