A sliding keel sailboat of the type comprises a sailing hull, a mast and a sailing arrangement whereon aero-dynamic forces, apt to be transferred to the hull through the mast, push, the mast being integral with a pivoting structure which can swing around a pivoting axis, parallel to a longitudinal central axis of the sailboat, in a respective seat in the sailing hull, the pivoting structure being arranged so that the crew can stand on it so as to balance the forces acting on the mast.

1. Sliding keel sailboat of the type comprising a sailing hull, a mast and a sail arrangement, said mast being mounted integral with a pivoting structure by a pivoting axis, parallel to a longitudinal central axis of the sailboat, to the hull structure,wherein said pivoting structure, free to rotate
1. Sliding keel sailboat of the type comprising a sailing hull, a mast and a sail arrangement, said mast being mounted integral with a pivoting structure by a pivoting axis, parallel to a longitudinal central axis of the sailboat, to the hull structure,wherein said pivoting structure, free to rotate relative to the sailing hull, is arranged so as to allow the crew to lean it to balance wind forces acting on the leeward tilting mast, wherein at least two extension plates are further provided, one for each sailboat edge, also said plates swinging, free of each other, about a longitudinal axis with respect to said pivoting structure, the lower position of said plates being determined, alternatively, by the contact with said pivoting structure or with the deck surface of the sailing hull. 2. Sliding keel sailboat as in claim 1, wherein said pivoting structure (5) or said mast (2) have a stabilization system.3. Sliding keel sailboat as in claim 2, wherein said stabilization system comprise a mass (M) having the center of gravity placed under said pivoting axis.4. Sliding keel sailboat as in claim 2, wherein said stabilization system comprise further a shock absorber device, operating between the sailing hull (1) and said pivoting structure (5).5. Sliding keel sailboat as in claim 1, wherein said pivoting structure (5), has a section shape as a circular sector.6. Sliding keel sailboat as in claim 5, wherein the lower peripheral surface of said pivoting structure (5) is a portion a cylindrical surface.7. Sliding keel sailboat as in claim 5, wherein constraint and guide means are provided between said pivoting structure and the relative seat in the sailing hull.8. Sliding keel sailboat as in claim 7, wherein said constraint and guide means are rails running over an arch of a circle.9. Sliding keel sailboat as in claim 1, wherein an anti-intrusion protection device is provided between said pivoting structure and said seat in the sailing hull.10. A sliding keel sailboat comprising:a sailing hull; a pivoting structure pivotal within a seat in said hull about a first axis parallel to a longitudinal central axis of the sailboat; a mast integrally mounted with said pivoting structure and pivotal about said first axis; and at least two extension plates on either side of said mast, said plates being independently swingable about a longitudinal axis with respect to said pivoting structure so that a lower portion of said plates are alternatively in contact with said pivoting structure and with a deck surface of the sailing hull, said mast being rotatable from a first position substantially perpendicular to said hull to a second position at an acute angle to said hull with respect to a leeward side of said sailboat, said pivoting structure being structured and arranged so that when said mast is in said second position, at least one crew member applies pressure to said pivoting structure from a windward side to balance wind forces acting on the mast. 11. The sliding keel sailboat as in claim 10, further comprising a stabilization system connected to at least one of said pivoting structure and said mast.12. The sliding keel sailboat as in claim 11, wherein said stabilization system further comprises a shock absorber device between the sailing hull and said pivoting structure.13. The sliding keel sailboat as in claim 10, further comprising an anti-intrusion protection device between said pivoting structure and said seat in said sailing hull.
