Claims
- 1. In a sailing craft, the combination of at least one hull having a bow and a stern in a longitudinal midplane a primary boom pivotally mounted on the at least one hull for 360.degree. continuous rotation in either direction about a central vertical axis, a sail boom connected to the primary boom, at least one angled mast mounted on the at least one hull, extending upwardly therefrom, the at least one mast having a top, the top being disposed approximately above the central vertical axis of the primary boom, a sail carried by the sail boom, the sail extending upwardly therefrom, and substantially symmetrical about the central vertical axis, the sail being supported from the top of the at least one mast, such that the sail boom with the sail thereon has a completely free 360.degree. rotation in either direction avoiding contact with the at least one mast.
- 2. The sailing craft of claim 1, further comprising the at least one hull having a deck, a port side and a starboard side, a cam having a base mounted on the hull deck at the central vertical axis, the cam being oriented toward the stern and disposed above the primary boom, the primary boom rotating about the base of the cam, the sail boom having a first end and an opposite second end, a first cam line connected from the cam to the first end of the sail boom, a second cam line connected from the cam to the second end of the sail boom, whereby when the primary boom rotates in a first direction, the first cam line is tightened and the second cam line is slackened, and when the primary boom rotates in a second opposite direction, the second cam line is tightened and the first cam line is slackened, whereby the luff and leach of the sail are interchangeable when the primary boom rotates through 180.degree..
- 3. The sailing craft of claim 2, wherein the slackened cam line has a length permitting movement of the sail boom through a predetermined distance port and starboard from the longitudinal midplane between the bow and the stern of the hull, said length being sufficient for tacking of the sailing craft without rotation of the primary boom and luffing through the wind preventing backwinding.
- 4. The sailing craft of claim 2, further comprising two cam cleats, a first cam cleat mounted on the first end of the sail boom and the second cam cleat mounted on the second end of the sail boom, each cam cleat having an alignment eye and a pair of interconnected jaws, the first cam line being received in the alignment eye and releasably retained in the jaws of the first cam cleat, the second cam line being received in the alignment eye and releasably retained in the jaws of the second cam cleat, wherein, pulling the respective cam line to release the respective cam line from the respective jaws, immediately pays out the sail boom for emergency situations and to depower the sail during knockdown, docking, and mooring.
- 5. The sailing craft of claim 1, further comprising the sail having a top, a halyard connected to the top of the sail, the halyard being routed from the top of the mast, along the mast to a halyard cleat connected to the mast, the halyard being pulled downwardly to raise the top of the sail to the top of the mast and the halyard being released to lower the sail.
- 6. The sailing craft of claim 5, further comprising a circular spring having a first end and a second end, the spring disposed around the mast, a retaining stop connected to the mast adjacent to the first end of the spring, a pulley attached to the second end of the spring, the halyard passing through the pulley and to the halyard cleat connected to the mast above the retaining stop, constant tension thereby being applied to the top of the sail.
- 7. The sailing craft of claim 1, further comprising the sail having a top, a foot and two sides therebetween, the foot being broader than the top, the foot of the sail being attached to the sail boom, a swivel plate attached to the top of the mast, a pair of sail flake lines, each sail flake line having a first end and a second end, the first ends of each sail flake line being attached to the swivel plate, a plurality of spaced-apart openings in the sail disposed in two parallel columns oriented from the top of the sail to the foot of the sail, each sail flake line passing through the openings in a respective column, the second ends of the respective flake lines being attached to the sail boom, wherein entanglement and twisting of the flake lines are avoided when the sail rotates through 360.degree. in either direction.
- 8. The sailing craft of claim 7, further comprising a hollow halyard tube connected to the swivel plate and extending upwardly therefrom, a halyard having a first end and a second end, the first end being connected to the top of the sail, the halyard passing through the halyard tube, the second end of the halyard extending downwardly toward the hull, wherein the halyard being pulled downwardly raises the top of the sail, the halyard being released flakes the sail downwardly along the flake lines.
- 9. The sailing craft of claim 1, further comprising a plurality of spaced-apart reef point openings in the sail, the openings being disposed in at least one row substantially parallel to the foot of the sail, a corresponding plurality of reefing ties, one of said reefing ties being disposed in each reef point opening and being tied around the sail boom when the sail is lowered.
- 10. The sailing ,craft of claim 1, wherein the sailing craft is a trimaran having a center hull, an outboard starboard hull and an outboard port hull.
- 11. A sailing craft having at least one hull, the hull having a deck, a port side, a starboard side, a bow and a stern in a horizontal plane, a primary boom pivotally mounted on the at least one hull for 360.degree. continuous rotation in either direction about a central vertical axis, a sail boom connected to the primary boom, at least one angled mast mounted on the at least one hull, the mast extending upwardly therefrom, the at least one mast having a top, the top being disposed approximately above the central vertical axis of the primary boom, a sail carried by the sail boom, the sail extending upwardly therefrom and substantially symmetrical about the central vertical axis, the sail being supported from the top of the at least one mast; a cam having a base mounted on the hull deck at the central vertical axis, the cam being oriented toward the stern and disposed above the primary boom, the primary boom rotating about the base of the cam, the sail boom having a first end and an opposite second end, a first cam line connected from the cam to the first end of the sail boom, a second cam line connected from the cam to the second end of the sail boom, whereby when the primary boom rotates in a first direction, the first cam line is tightened and the second cam line is slackened, and when the primary boom rotates in a second opposite direction, the second cam line is tightened and the first cam line is slackened, whereby the luff and leach of the sail are interchangeable when the primary boom rotates through 180.degree., the ends of the sail boom and the sail avoiding contact with the at least one mast.
