A sailboat has a preferably solid hull with lateral and longitudinal symmetry, a centrally located ring-shaped seat secured to a central portion of the top of an hull, a selectively rotatable carousel being mounted about an outer circumferential wall of said ring-shaped seat, a frame being secured to said carousel for retaining a pair of spaced apart identical sails that slant inward toward one another, a pair of removable selectively rotatable cylindrical booms being positioned on the frame with an associated halyard system for controllably furling and allowing easy reefing of the pair of sails, a pair of selectively removable rotatable hydrofoils each serving as a rudder and centerboard projecting downward from the bottom of and proximate the ends of the hull, a steering wheel being secured to the hull at the center of the ring-shaped seat and linked to each of the hydrofoils, whereby the carousel can be selectively rotated to position the sails at any desired angular position relative to the direction of the wind, without interfering with crew members who sit facing inward on the ring-shaped seat. Color-coded spaced-apart markings about a top circular portion of the carousel, relative to stripes applied to the top of the seat, show at a glance the angle of the frame to the seat, representative of the angle of the sails to the hull.

What I claim is: 1. A sailboat comprising: a hull having both lateral and longitudinal symmetry, first and second ends, a top, and a bottom; a ring shaped seat rigidly secured to a center portion of the top of said hull, for permitting crew and/or passengers to sit thereon facing inwards; first and second sails; a carousel frame rotatably mounted about circumferential sidewalls of said seat; and a rigid frame structure secured to said carousel frame for supporting said first and second sails in spaced apart opposition to one another, thereby permitting said carousel frame to be rotated for positioning said first and second sails to a desired position relative to the direction of the wind, without interfering with or requiring said crew and/or passengers to change their position on said seat. 2. The sailboat of claim 1, further including: first and second selectively rotatable vertical hydrofoils proximate said first and second ends of said hull, and projecting downward from the bottom thereof, said hydrofoils each serving as both a rudder and centerboard. 3. The sailboat of claim 1, wherein said first and second sails are identical in shape. 4. The sailboat of claim 3, wherein said frame structure is configured to provide that wind pressure tends to rotate said carousel frame to position said first and second sails to a neutral position in which they are feathered, in the absence of a force restraining said carousel frame from so rotating. 5. The sailboat of claim 3, wherein said frame structure is configured to provide for said first and second sails to be slanted with their heads closer together than their feet, for reducing a heeling moment, but with said sails spaced far enough apart to minimize aerodynamic interference. 6. The sailboat of claim 1, wherein said frame structure is further configured to provide for said first and second sails to be slanted with their heads closer together than their feet, for reducing a heeling moment, but with said sails spaced far enough apart to minimize aerodynamic interference. 7. The sailboat of claim 1, further including: first and second selectively rotatable cylindrical booms being removably mounted on said frame structure in association with said first and second sails, respectively; and a plurality of halyards for connecting said first and second sails to said first and second booms, respectively, and to said frame structure, for permitting said sails to be furled or unfurled to the extent desired relative to their respective boom. 8. The sailboat of claim 7, wherein said first and second sails are each triangularly shaped to provide that a center of effort is the same at fore and aft locations, respectively, for every degree of furling said sails, thereby insuring that for each sail an offset of the sail force relative to a center of rotation of said carousel frame remains the same when the respective sail's exposed area is reduced by partial furling. 9. The sailboat of claim 8, further including: first and second reels individually integral with said first and second booms, respectively; a plurality of pulleys mounted on said frame structure; one of said plurality of halyards running from the head of an associated one of said first and second sails over individual ones of said plurality of pulleys, to an associated one of said first and second reels, to provide for furling and unfurling the associated sail; and said first and second reels each being shaped to insure the maintenance of constant tension on their associated halyard throughout its travel. 10. The sailboat of claim 9, further including: first and second pairs of cam cleats associated with each one of said first and second sails, respectively; one cleat of one of said pairs of cam cleats being secured to said frame structure proximate a top of its associated sail, the other cleat of said one of said pairs of cam cleats being secured to the said frame structure proximate a bottom of its associated sail, said one and the other cleats providing for selectively securing their associated halyard to tension their associated sail, or releasing their associated halyard to further furl or unfurl the associated sail. 11. The sailboat of claim 10, wherein said rigid frame supports a tension load from both sails without imparting any significant portion of that load to the carousel frame or other parts of the boat, and comprises: a first mast having a top end and a bottom end; a first pair of struts, which, by their compression, transmit a tension load of a first sail from the ends of said first boom to the bottom end of said first mast, which is coplanar with said pair of struts, and which first mast by its compression, transmits the tension load from its bottom end to its top end, the top end being connected to the head of said second sail; a second mast having a top end and a bottom end; a second pair of struts, symmetrically situated with respect to said first pair of struts, which transmit the tension load from the ends of said second boom to the bottom end of said second mast, which is coplanar with said second pair of struts, and which transmits the tension load to its top end, which is connected to the head of said first sail; a stay connecting the tops of the two masts; a first set of three stays connecting the bottoms of said first pair of struts and the top end of said second mast in a triangular configuration; and a second set of three stays connecting the bottoms of said second pair of struts and the top end of said first mast in a triangular configuration. 12. The sailboat of claim 11, further including: a wind indicator; a pair of spars each having one end connected individually to a central portion of one of said first and second masts, respectively, and another end connected rigidly to said wind indicator; a fourth cable connected between said wind indicator and an upper portion of the associated one of said first and second masts; and a fifth cable connected between said wind indicator and said rigid frame structure; said wind indicator being positioned to insure that it does not interfere with the raising and lowering of said first and second masts. 13. The sailboat of claim 12, further including: a plurality of color coded markings equally spaced about the periphery of the carousel frame; and a pair of diametrically opposed markings applied on the top of said ring shaped seat proximate its circumferential edge; the combination of said color coded markings and one of said pair of diametrically opposed markings permitting a skipper of said sailboat to tell at a glance the angle at which said carousel frame is set relative to said hull at any given time, for setting the positioning of said sails to the wind. 14. The sailboat of claim 2, further including: a wheel; a linkage shaft having one end pivotally connected to a top circular portion of said first hydrofoil, and another end pivotally connected to a top circular portion of said second hydrofoil at a position thereon that is 180 degrees displaced from the relative position of said one end as connected to said first hydrofoil, whereby movement of said linkage shaft causes said first and second hydrofoils to rotate in opposite directions; and a flexible line connected between said wheel and said linkage shaft, whereby rotation of said wheel causes movement of said linkage shaft for positioning said first and second hydrofoils to steer said sailboat. 15. The sailboat of claim 1, wherein said rigid frame supports a tension load from both sails without imparting any significant portion of that load to the carousel frame or other parts of the boat, and comprises: a first mast having a top end and a bottom end; a first pair of struts, which, by their compression, transmit the tension load of a first sail from the ends of said first boom to the bottom end of said first mast, which is coplanar with said pair of struts, and which first mast by its compression, transmits the tension load from its bottom end to its top end, the top end being connected to the head of said second sail; a second mast having a top end and a bottom end; a second pair of struts, symmetrically situated with respect to said first pair of struts, which transmit the tension load from the ends of said second boom to the bottom end of said second mast, which is coplanar with said second pair of struts, and which transmits the tension load to its top end, which is connected to the head of said first sail; a stay connecting the tops of the two masts; is a first set of three stays connecting the bottoms of said first pair of struts and the top end of said second mast in a triangular configuration; and a second set of three stays connecting the bottoms of said second pair of struts and the top end of said first mast in a triangular configuration. 16.
