1. A set of stowable rigid sails with an aerodynamic profile, comprising: a plurality of sails, each sail comprising: a number of vertically extendable masts,a number of substantially horizontal frame sections that longitudinally and vertically move on said masts from a stacked position, in which said frame sections keep in contact with each other, to a deployed working position in which said frame sections are placed along the masts, anda plurality of rigid panels to conform the side surface of each sail, said panels being hinged with the frame sections and to each other and said panels being operative between two positions: (i) an unfolded position, in which said frame sections are deployed and said panels are substantially coplanar and substantially longitudinally aligned in a substantially vertical direction to conform the side surface of each sail, and (ii) a folded position, in which the panels are stacked and kept in contact with each other, together with the frame sections. 2. The set of stowable rigid sails of claim 1, further comprising a number of hydraulic cylinders that are operable to extend and to retract the masts. 3. The set of stowable rigid sails of claim 1, further comprising a number of hinged prolongations, and rotatable hinges that join the panels to the sections and to the hinged prolongations. 4. The set of stowable rigid sails of claim 1, further comprising a number of hinges that join the panels to each other. 5. The set of stowable rigid sails of claim 1, further comprising a number of struts that join the frame sections consecutively, a first end of a first strut being fixed to a lower part of a first frame section, and a second end being positioned in a hole defined in the first frame section and abutting a housing of a second frame section. 6. The set of stowable rigid sails of claim 1, further comprising a number of actuators coupled to the sections the actuators being configured to permit the movement of the sections relative to the masts. 7. The set of stowable rigid sails of claim 1, further comprising a base with pulleys and a carcass-fixed to the ends of each upper length of each of the masts. 8. The set of stowable rigid sails of claim 7, further comprising a cable configured to slide relative to the pulleys the cable including a first end fixed to a first frame section and a second end fixed to a cable base, said cable base being integral with an end of the telescopic mast such that at the unfolded position of the masts, the last frame section is positioned at the end of the upper length of the mast and in the folded position, the last frame section is stacked with the other frame sections. 9. The set of stowable rigid sails of claim 7, further comprising an elastic envelope fixed to the carcass at a first end and to the upper section at a second end such that when the sails are folded, the elastic envelope covers the plurality of sails to favour the aerodynamics, and when the sails are unfolded the elastic envelope is positioned within the carcass. 10. The set of stowable rigid sails of claim 1, wherein the panels have hydraulic, mechanical or electromechanical driving means to move the panels to define an output edge. 11. The set of stowable rigid sails of claim 1, further comprising a number of curved panels coupled to the panels along by hinges. 12. The set of stowable rigid sails of claim 1, further comprising a number of cylinders and a number of struts configured to (i) move the panels to adapt to the shape of the frame sections to form an attack edge of the profile in the unfolded position and (ii) obtain an alignment between the panels in the folded position. 13. The set of stowable rigid sails of claim 1, wherein the plurality of sails are arranged in opposed pairs. 14. The set of stowable rigid sails of claim 1, wherein the plurality of sails are mounted on a boat hull. 15. The set of stowable rigid sails of claim 14, further comprising a turbine for generating a brake effect to transform the wind power into rotation power at the axis of said turbine. 16. The set of stowable rigid sails of claim 15, further comprising a means for generating electric power by an alternator/dynamo associated with the turbine or pressurised air by a compressor associated with the turbine to store air in high pressure tanks housed inside the hull. 17. The set of stowable rigid sails of claim 15, wherein said masts are telescopically extendable.
