An integral sail to generate a propulsion following a thrust from the wind has an integral layered structure delimited externally by a first external layer (11) and by a second external layer (111), both made with a smooth layer of thin and continuous film of flexible material. Furthermore, to each of said first external layer (11) and second external layer (111) at least a layer of parallel fibers (12, 112, 212, 312), adjacent to each other, is associated internally with respect to the layered structure. The whole is made solid by means of at least a layer of thermofusible glue (14, 114, 214, 314), disposed inside the external layers (11, 111) and in coordination with the corresponding layers of parallel fibers (12, 112, 212, 312).
