WebJun 6, 2024 · The fundamental purpose of a Load Line is to allow a maximum legal limit up to which a ship can be loaded by cargo. By prescribing such limits, the risk of having the vessel sailing with inadequate freeboard and buoyancy can be limited. A vessel should have sufficient freeboard at all times.

WebApr 26, 2024 · For an empty ship which has no cargo loaded, displacement is less and hence the draft is less. There is less resistance as the lesser surface of the hull is in contact with water and as there is not much load on the main engine, it gives more speed at less power. WebShip tonnage is a measure of what a ship can carry. The two major categories of ship tonnage are tonnage by weight and tonnage by volume (Fig. 8.34). Tonnage by weight, or …

WebA displacement hull is a boat hull design that uses buoyancy to support its weight. It lies partially submerged and displaces water when moving, hence its name. The amount of water it displaces is equal to its weight. It's very stable in rough waters. That's why this design is widely used on cruisers and sailboats.
