Definition This type of hull fits nearly between the displacement and planing hull types. Its stern is low and designed to be always below the water. The hull can have a round bilge form, but it is generally of the “Hard chine” type. These hulls have less fullness than a full displacement hull. Semi-displacement hulls can be driven harder, but at the expense of greater fuel consumption, and the stern will tend to dig in at higher speeds.
Definition source Piercey 2002
Context This boat is a semi-displacement hull powered by twin 2285-hp engines with a top speed of 23 knots and a cruising one of 18 (at which, by the way, she also had a 1,200-mile range).
