Claims
- 1. Method of increasing the forward velocity of a sailing vessel having a rotatable fin and a ballast supporting member extending downwardly from the sailing vessel, the ballast supporting member carrying a ballast bulb at its lower end which comprises the step of isolating the supporting member of the ballast bulb from water passing therearound when the vessel is sailing.
- 2. Method according to claim 1 wherein the rotatable fin is partially hollow and which includes the step of jacketing said rotatable fin around said ballast support member to isolate the ballast support member from water passing therearound when the vessel is sailing.
- 3. A sailing vessel having a canoe body with a waterline therearound and an appendage depending therefrom, said appendage comprising a ballast bulb support member adapted to be fixed to the canoe body, a ballast bulb adapted to be fixed to the outer end of said ballast bulb support member, means isolating said ballast support member from moving water when the vessel is sailing, said means including a hollow fin adapted to be rotatable around the external surface of said ballast bulb support member and means fixing and releasing the rotation of the rotatable fin around the ballast bulb support so as to position said fin at a selective angular displacement relative to the fore and aft axis of the canoe body, the rotatable axis of said fin being perpendicular to the plane of said water line.
- 4. A sailing vessel according to claim 3 wherein said ballast bulb support member is four sided.
- 5. A sailing vessel according to claim 4 wherein said ballast support member is diamond shaped having a major and minor axis, the major axis being parallel to the fore and aft axis of the canoe body and the minor axis being perpendicular to the fore and aft axis of the canoe body.
- 6. A sailing vessel according to claim 5 wherein the inner surface of said rotatable fin at its minimum dimension and the outer surface of said ballast bulb support at its minimum dimension are curved and positioned so that they are slidable relative to each other.
- 7. A sailing vessel according to claim 6 wherein the curved surface on the interior of the fin is concave and the curved surface on the exterior of the ballast bulb support is convex.
- 8. A sailing vessel according to claim 7 including a first cylindrical member fixed at its bottom end to the cabin sole of the interior of the canoe body and at its top end to the cabin top, said ballast support member at its two major apexes being fixed to the interior of said first cylinder.
- 9. A sailing vessel according to claim 8 including a second cylindrical member fixed at its bottom end to the cabin sole and means anchoring the top end of said cylindrical member to said first cylindrical member.
- 10. A sailing vessel according to claim 9 wherein the vertical axes of first and second cylindrical members are perpendicular to the plane of said waterline of the canoe body, and including means to support said first and second cylindrical members along the fore and aft axis of the canoe body in perpendicular relationship to the plane of said waterline therearound.
- 11. A sailing vessel according to claim 10 wherein said means to support said first and second cylindrical members includes a plurality of diagonal members surrounding said first and second cylindrical members fixed at their lower ends to said cabin sole and fixed at the their top ends to said cabin top, and means anchoring said first and second cylindrical members to the plurality of said diagonal members.
- 12. A sailing vessel according to claim 11 wherein said second cylindrical member has an internal diameter slightly greater than the chord dimension of said rotatable fin, said portion of the top end of said rotatable fin residing in the interior of said second cylinder, including means to slidably support the bottom end of said rotatable fin upon said ballast bulb and means to rotate said rotatable fin around said ballast support means.
- 13. A sailing vessel according to claim 12 including rib members fixed to said ballast bulb support and to the interior of said first cylinder.
- 14. A sailing vessel according to claim 13 which comprises generating a hydrodynamic force directed to counter the wind force which is moving the canoe body leewardly, the net leeward wind force reducing the leeward drift distance of the canoe body and thereby reducing the leeward drift energy of the canoe body, the savings in said leeward drift energy being transferred to the portion of the wind energy which propels the canoe body forwardly in accordance with the Laws of Thermodynamics which state that energy is indestructible and instead is transferable.
- 15. A sailing vessel according to claim 14 wherein said ballast support member is fixed to said first cylinder with its fore and aft axis parallel to the fore and aft axes of the canoe body, and said canoe body is tacking into the wind with its rotatable fin pointed at an angle to the water track so that said fin is generating an asymmetrical effect to decrease the leeward drift of the canoe body in accordance with the Energy Balance of the following formula:
