A displacement hull is an efficient, non planing hull that moves through the water at 1.34 times the square root of the waterline length (LWL). This is not "directly" related to the designed displacement of the boat, that is, usually the weight of the boat, all additional gear, fuel, water, crew, cargo and everything else on board. Besides being efficient a displacement hull is usually more capable in rough weather and requires a relatively small inexpensive engine.
