The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship … See more • The draft aft (stern) is measured at the perpendicular of the stern. • The draft forward (bow) is measured at the perpendicular of the bow. • The mean draft is obtained by calculating from the averaging of the … See more Large ships Larger ships need to keep the propeller immersed when they are light (without cargo), and may ballast further to reduce windage or for better directional stability or seakeeping, or to distribute load along the hull to reduce … See more • Hayler, William B.; Keever, John M.
