초록▼
The invention comprises a waterborne craft having a hull, board or base, and a fin, keel, centerboard or the like. One or more air conduits exit the hull, board or base at or adjacent at least one side of the fin, keel or centerboard, or exit the fin, keel, or centerboard, excluding the leading edge
The invention comprises a waterborne craft having a hull, board or base, and a fin, keel, centerboard or the like. One or more air conduits exit the hull, board or base at or adjacent at least one side of the fin, keel or centerboard, or exit the fin, keel, or centerboard, excluding the leading edge of the fin, keel or centerboard in use, in a position such that the conduit in use provides or the conduits in use provide air to a position at or adjacent at least one side of the fin, keel or centerboard.

1. A waterborne craft, comprising: a board having an upper surface and a lower surface; anda fin extending from the lower surface,the board having an air conduit passing through a thickness of the board, the air conduit having an inlet end on or adjacent the upper surface, and an outlet end on the lower surface of the board, the outlet being positioned at or adjacent a leading edge of the fin such that the conduit, in use, provides air to a position at or adjacent to the leading edge of the fin in order to reduce drag to the fin and not the lower surface of the board,said air conduit being i) located completely outside of said fin and ii) does not pass through the fin. 2. The waterborne craft as claimed in claim 1, wherein the conduit takes the form of plural apertures through the board. 3. The waterborne craft as claimed in claim 2, wherein the apertures are located at or adjacent the at least one side of the fin. 4. The waterborne craft as claimed in claim 3, wherein the apertures each form an air exit at or adjacent a side of the fin, and each have a reduced diameter at or adjacent the air exit end thereof. 5. The waterborne craft as claimed in claim 2, wherein the apertures each form an air exit at or adjacent a side of the fin, and each have a reduced diameter at or adjacent the air exit. 6. The waterborne craft as claimed in claim 5, wherein the fin has three or four of said apertures located therebeside. 7. The waterborne craft as claimed in claim 2, comprising a plurality of fins, wherein the apertures are each positioned to provide air to at least one side face of at least one of said plurality of fins. 8. The waterborne craft as claimed in claim 7, wherein the apertures each form an air exit at or adjacent a side of the fin, and each have a reduced diameter at or adjacent the air exit end thereof. 9. The waterborne craft as claimed in claim 1, comprising a plurality of fins, wherein the conduit takes the form of an aperture positioned to provide air to at least one side face of at least one of said plurality of fins. 10. The waterborne craft as claimed in claim 9, comprising a plurality of apertures through the board each located at or adjacent at least one side of at least one of said plurality of fins.
