Abstract
This invention provides a water craft hull having an air chamber, wherein the sidewalls of the air chamber extend lower than the fore wall and the aft wall of the air chamber, and wherein the hull comprises at least one air injector configured to deliver pressurized air to the air chamber. Optionally, a hull of the invention has a high aspect ratio air chamber defined by a stable fore wall, a stable aft wall, and stable sidewalls, is a non-planing hull, has a wave-piercing bow, and has elongated keel fins (e.g. inner keel fins and/or outer keel fins). Optionally, the air chamber is configured for recirculating air flow.
Claims14
A water vessel hull comprising an air chamber and at least one air injector configured to deliver air to the air chamber, wherein:
- the air chamber comprises an open base and is enclosed by an upper wall, a fore wall, an aft wall, and sidewalls;
- the sidewalls extend lower than the fore wall and the aft wall;
- each of the side walls, the fore wall, and the aft wall comprises a stable wall;
- the hull comprises a bow forward of the fore wall;
- and
- a nose of the bow is positioned at a height that is lower than the top of the air chamber and higher than a base of the air chamber;
- and
- optionally, the nose of the bow is positioned at a height that is closer to the height of a base of the stable fore wall than the height of the top of the stable fore wall.
A water vessel hull comprising an air chamber and at least one air injector configured to deliver air to the air chamber, wherein:
- the air chamber comprises an open base and is enclosed by an upper wall, a fore wall, an aft wall, and sidewalls;
- the sidewalls extend lower than the fore wall and the aft wall;
- and
- each of the side walls, the fore wall, and the aft wall comprises a stable wall;
- and
- further comprising fins extending laterally from each side wall, wherein:
- the fins extend laterally from the side walls at a location lower than the base of the air chamber, optionally, wherein the fins extend laterally from the base of the side walls;
- the fins are elongated fins;
- and
- the longitudinal span of the elongated fins is at least about 10 times greater than the lateral span of the elongated fins, optionally wherein ratio of the longitudinal span of the elongated fins to the lateral span of the elongated fins is at least about 15:1, at least about 20:1, or at least about 30:1.
A water vessel hull comprising an air chamber and at least one air injector configured to deliver air to the air chamber, wherein:
- the air chamber comprises an open base and is enclosed by an upper wall, a fore wall, an aft wall, and sidewalls;
- the sidewalls extend lower than the fore wall and the aft wall;
- and
- each of the side walls, the fore wall, and the aft wall comprises a stable wall;
- and
- further comprising fins extending laterally from each side wall, wherein:
- the fins extend laterally from the side walls at a location lower than the base of the air chamber, optionally, wherein the fins extend laterally from the base of the side walls;
- and
- the fins comprise a fin that extends inwards from the each sidewall and a fin that extends outwards from the each sidewall, optionally wherein the fin that extends inward extends inward from the each side wall at a location lower than the air chamber and the fin that extends outward extends outward from the each side wall at a location lower than the air chamber.
A water vessel hull comprising an air chamber and at least one air injector configured to deliver air to the air chamber, wherein:
- the air chamber comprises an open base and is enclosed by an upper wall, a fore wall, an aft wall, and sidewalls;
- the sidewalls extend lower than the fore wall and the aft wall;
- and
- each of the side walls, the fore wall, and the aft wall comprises a stable wall;
- and
- further comprising fins extending laterally from each side wall, wherein:
- the fins extend laterally from the side walls at a location lower than the base of the air chamber, optionally, wherein the fins extend laterally from the base of the side walls;
- and
- the air chamber is an air chamber having a height that is greater than the width.
A water vessel hull comprising an air chamber and at least one air injector configured to deliver air to the air chamber, wherein:
- the air chamber comprises an open base and is enclosed by an upper wall, a fore wall, an aft wall, and sidewalls;
- the sidewalls extend lower than the fore wall and the aft wall;
- and
- each of the side walls, the fore wall, and the aft wall comprises a stable wall;
- and
- further comprising fins extending laterally from each side wall, wherein:
- the fins extend laterally from the side walls at a location lower than the base of the air chamber, optionally, wherein the fins extend laterally from the base of the side walls;
- and
- the air chamber is configured to recirculate air.
