NettetExamples include passenger ships, most naval vessels, cargo ships with high stowage rates (such as for meat, bananas and cars) passenger/car ferries and container ships. 9.2.4.1 Cargo Ships The capacity design approach for this vessel type is based on the equality: V C =V H −V S , where V C =vol. available for cargo, V H =total underdeck … NettetThe ship is said to hog or sag when the curvature is concave down or up respectively. The amount of hog or sag is the difference between the actual draught amidships and the mean of the draughts at the fore and after perpendiculars. In calculations, the curvature of the ship due to hog or sag is usually taken to be parabolic in shape.
