Abstract

An air supported vessel comprising a basically V-shaped hull with a starboard keel part and a port keel part and with a V-shaped bow, which includes an outer bow support surface, where the basically V-shaped hull has at least one air cushion chamber in a substantial part of the basically V-shaped hull's length below the waterline, and where the air supported chamber is delimited by an air supported chamber ceiling, air supported chamber starboard and port side walls and with at least one aft closing device with an aft threshold that forms an aft delimitation of the air supported chamber and with at least an air supported chamber air intake which, together with the side wall of the air supported chamber in the bow, forms the front delimitation of the air supported chamber.

IPC Classes  ?

• B60V 3/06 - Waterborne vessels
• B60V 1/04 - Air-cushion vehicles wherein the cushion is contained at least in part by walls
• B60V 1/08 - Air-cushion vehicles wherein the cushion is created during forward movement of the vehicle by ram effect
• B60V 1/18 - Body structure
• B63B 1/32 - Other means for varying the inherent hydrodynamic characteristics of hulls
• B63B 1/38 - Other means for varying the inherent hydrodynamic characteristics of hulls by reducing surface friction using air bubbles or air layers

IPC Classes  ?

• B63B 1/04 - Hydrodynamic or hydrostatic features of hulls or of hydrofoils deriving lift mainly from water displacement with single hull
• B63B 1/20 - Hydrodynamic or hydrostatic features of hulls or of hydrofoils deriving additional lift from hydrodynamic forces of hydroplane type having more than one planing surface
• B60V 3/06 - Waterborne vessels
• B60V 1/08 - Air-cushion vehicles wherein the cushion is created during forward movement of the vehicle by ram effect

Abstract

An air supported vessel comprising a basically V-shaped hull with a starboard keel part and a port keel part and with a V-shaped bow, which includes an outer bow bearing surface, where the basically V-shaped hull has at least one air supported chamber in a substantial part of the basically V-shaped hull's length below the waterline, and where the air supported chamber is delimited by an air supported chamber ceiling, air supported chamber starboard and port side walls and with at least one aft closing device with an aft threshold that forms an aft delimitation of the air supported chamber and with at least an air supported chamber air intake which, together with the side wall of the air supported chamber in the bow, forms a forward delimitation of the air supported chamber, and which has a starboard keel part, which comprises a starboard longitudinal keel step and a starboard keel step threshold, which in turn forms a lower starboard lateral delimitation of the air supported chamber's starboard side wall, to reduce air leakage under a starboard keel line and opposite on the port side, with a port keel part, which comprises a port longitudinal keel step and a port keel step threshold, which in turn forms a lower port lateral delimitation of the air supported chamber's port side wall, to reduce air leakage under a port keel line.
