Abstract: A propulsion system for a water craft having at least one shaft extending rearwardly form the transom of the hull of the craft and a drive system for driving the at least one shaft. A surface piercing propeller is mounted on the at least one shaft, proximal to the trailing edge of the hull, so that the propeller operates in a transom cavity created behind the hull, in use of the craft. The ratio (S/C) of the spacing of the blades to the blade cord for each propeller is at least 2.0 along substantially the whole length of the blades. The propulsion system has a high operational efficiency particularly suited for high speed marine craft.

Abstract: The application relates to water craft hulls having improved hydrodynamic stability. A hull (1) is claimed in which the center of gravity (Cg) is substantially vertically aligned with the center of hydrodynamic lift (Cp) of a lifting surface of the hull, both at lift-off speed and at design speed, and preferably also at speeds below lift-off, and at all speeds between lift-off and design speed and above. A hull having a relatively high aspect ratio at design speed, and preferably also at lift-off speed, is also claimed. In the preferred embodiment, the hull is generally delta-shaped in plan view.

Abstract: The invention relates to hulls for planing or semi-planing water craft. The hull (4) has an abruptly down-swept trailing edge portion (18) which, in the preferred embodiment, is in the form of a flap extending across the full width of the transom of the hull and which projects beyond the level of an upswept portion of the underside (14) of the hull by only a small fraction of the length (L) of the hull. According to another aspect of the invention, a hull (4) having a lightly cambered nose portion (5, 10, 12) is also described and claimed. The claimed hulls offer higher lift coefficients and lift/drag ratios than conventional planing hulls, and can operate at zero angle of attack at design speed.
