         6 . The sailboat according to  claim 1 , wherein said support element ( 16 ) or raised element ( 27 ) can be an integral part of the hull ( 22 ) and form a single element with the hull; or, alternatively, said support element ( 16 ) or raised element ( 27 ) can be an element that can be mounted, positioned and adjusted at will by means of special fixing and adjustment means ( 230 ,  231  e  232 ) located in proximity of the stern ( 53 ). 
     
     
         7 . The sailboat according to  claim 1 , wherein along the edge of the hull ( 22 ) or in positions adjacent thereto of the deck ( 15 ) of the hull ( 22 ), along the extension direction (X), there are present some gripping elements, closed or open, shaped like a closed or open handle fixed on the hull, to facilitate sailing, climbing on board, rescuing people, gripping if need be and safety in general. 
     
     
         8 . A multifunctional board or “multitasking” board comprising a hull ( 22 ) extending along a main extension direction (X) with a lower surface ( 23 ), designated to be partly or fully submerged in water, and an upper surface ( 24 ), suitable to accommodate a helmsman ( 51 ), characterised in that said hull ( 22 ) has—along the two edges thereof, extending along the axis (X)—an ansa lunata ( 25 ) and an ansa lunata ( 26 ), respectively, each of which extends along the axis (Y). 
     
     
         9 . The multifunctional board according to  claim 8 , wherein said hull ( 22 ) comprises a support element ( 16 ) or a raised element ( 27 ), with respect to the surface of the deck ( 15 ) of the hull ( 22 ), which is positioned in proximity of the stern ( 53 ) of the hull ( 22 ); said raised element, preferably a pillow ( 28 ), is an integral part of the hull ( 22 ) and forms a single element with the hull; or, alternatively, it can be an element that can be mounted, positioned and adjusted at will using special fixing and adjustment means ( 230 ,  231  and  232 ) located in proximity of the stern ( 53 ), preferably said support element ( 16 ) or raised element ( 27 ) obtaining at least one backrest or a chaise longue for the helmsman ( 51 ).
