摘要:
The disclosed is for a specifically designed ski structure to support a vessel's hull above the water surface while the vessel is underway so that the hull encounters minimal or no resistance from the water, the viscosity of which is 800 times greater than air. The skis, which may number more than two per vessel, are arranged in parallel to the vessel's direction of travel and support the hull from beneath via stanchions that may be of a fixed nature or capable of lifting and lowering the hull relative to the ski structures' planing position on the water surface. The skis would normally be positioned to the sides of the hull's beam to impart maximum stability to the vessel. The ski structures are designed to have multiple functions: a.) to enable sea vessels to travel at very much higher speeds than conventional designs afford; b.) To provide a lightweight, rigid structure that is able to be reinforced within itself; c.) Through their design shape and internal reinforcing to be able to bear considerable weight imposed by the vessel and its cargo; d.) To enclose air (or other friction reducing agents) in entrapment zones between the underside of the skis and the water surface; e.) To provide directional stability to the vessel through the structures' design elements; f.) To contribute wave piercing attributes through the structures' design elements; g.) To enable the ski structures to shed water readily due to the structures' design elements; h.) To provide watertight housing within the structures' for fuel and/or cargo storage and for housing the vessel's motors and drive trains (larger vessels). The ski structures may be made from any suitable metals, timber, plastics or composites thereof. Each ski structure generally consists of two complementary ski surfaces (with upward curves at their leading or entry points). The main ski surface (1 ) has a pair of assist skis or 'glides' (2) that are arranged on either side of the main ski surface (1 ). These elements are attached to and supported by the ski structure's main assembly, a longitudinal shell (3), which may or may not contain reinforcing (4) within its watertight housing (6) that may also be utilised to house fuel and the vessel's engines and drive train components on larger scale vessels. The longitudinal shell (3), front-on in cross section, has the shape of an inverted 'U' the ends or edges (5) of which impart a keel-like activity to the ski structures to provide directional stability and prevent yawing. The edges (5) also provide an air entrapment zone (7) between them and the underside of the main ski surface (1 ) and the water surface where air, or any friction reducing agent, may be induced into the zone to provide a friction relieving interface between the water surface and ski undersides. The assist skis (2) are attached to the assembly at a lower level than the main ski surface (1 ) and become the main contact with the water surface at speed, allowing a cushion of air to be provided in the entrapment zone (7) for the main ski surface (1 ). The assist skis may also be designed to provide an air entrapment zone of their own by having a downward lip on their outer extremities running the length of the skis.

A hull for shipping with a mono-catamaran architecture has a front hull part (10) with a deep V-shape contour having an angle gradually increasing fore and aft to become a straight angle in a rear hull part (14) with chines extending according to a wing contour. The chines, starting from the stern, have a lower edge situated under the waterline (20) astern of the midship cross section and then raise being radiused with the front hull part (10).

Schnellaufendes Boot, das einen Bootskörper mit einem Vordersteven, einem Heck, zwei Seitenwandungen sowie einer Bodenplatte mit einer Bodenhimmelfläche aufweist, wobei auf der Bodenhimmelfläche seitlich je eine Gleitkufe mit Gleitstufen und vorzugsweise in der Mittschiffsebene eine Kielkufe mit Kielstufen angeordnet ist, und zwischen den Gleitkufen mindestens ein Lüftungskanal gebildet wird, und wobei der Bootskörper vorzugsweise mit einer Bugflosse ausgerüstet ist, wobei die freie Bodenhimmelfläche vornehmlich im Bereich zwischen Bootslängsmitte und Heck eine vorzugsweise bis zum Heck abfallende Schräge aufweist.
摘要:
A method for creating a parametric planing hull model is disclosed. In one embodiment, dimensions of a plurality of hull sections, including two non-adjacent hull sections, are received from a user. Dimensions of at least one hull section between the two non-adjacent hull sections are interpolated. Curves of the hull are generated based on the dimensions of the plurality of hull sections received from the user and the interpolated dimensions of the at least one hull section between the two non-adjacent hull sections. Surfaces of the hull are created based on the generated curves, and a planing hull model is generated from the created surfaces and is displayed.

The invention concerns a hull (1) for sailing craft enabling water gliding performances to be enhanced. The hull (1) for a sailing craft comprises a bottom (2) which has a particular profile. Said bottom (2) is characterized in that it comprises a rail (3) shaped from the stem up to the transom, said rail (3) being formed by a flat axial sole (6) linking two parallel passageways of the stem to the transom, of similar width, of similar depth of the water inlet at the transom exit, the passageways derived from the sole (6) have a cross-sectional profile on either side of the sole (6) to form two V-shaped inclined planes (9, 10) and are terminated by two arcs of a quarter circle which are further extended by two other inclined parts (13, 14) forming another V-shape less inclined than the first and leading to the upper works (15, 16). The invention is applicable to boats.
摘要:
A floating hull comprising a bottom shell (1) and a wall (2) defined by two bilges (3) and having a front part (7) and a rear part (8). The front part (7) and rear part (8) are offset in relation to each other in a V-shape in the stepped bulkhead (6) whereby the tip thereof is oriented towards the front. The hull has a centre line (5) and is characterized in that the spread of the stepped bulkhead (6) extends transversally between the two bilges (3) and in the two tapered lateral (11) base blocks (11) are provided on the rear part (8), protruding from each bottom shell (1) in the vicinity of a bilge (3) and whose longitudinal axis is substantially parallel to the corresponding bilge (3).
摘要:
Coque pour bateau à moteur rapide dont la partie de proue en forme de V comporte une étrave dure (6) se fondant dans une quille (7). La quille est divisée au milieu du bateau en deux parties arrière (8, 9) de quille dure, divergeant vers l'arrière, entre lesquelles est prévu, sur le dessous de la coque, un tunnel (10) ouvert à l'arrière et s'étendant vers l'avant tout en convergeant vers l'intérieur. L'extrémité avant dudit tunnel peut être définie par une cloison étanche (11) située à l'extrémité arrière de la partie de quille dure de l'avant (7), le tunnel pouvant communiquer avec l'atmosphère par la coque, par exemple par la cloison étanche (11).
