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 and by a second external layer, both made with a smooth layer of thin and continuous film of flexible material. Furthermore, to each of said first external layer and second external layer at least a layer of parallel fibers, 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, disposed inside the external layers and in coordination with the corresponding layers of parallel fibers. |

1. Integral sail to generate a propulsion following a thrust from the wind, characterized in that it has an integral layered structure delimited externally by a first external layer and by a second external layer, both made with a smooth layer of thin and continuous film of flexible material, and in that to each of said first external layer and second external layer at least a layer of parallel fibers, adjacent to each other, is associated internally with respect to said layered structure, wherein at least a layer of parallel fibers cooperating with the first external layer provides its fibers disposed parallel also to the fibers of another layer of parallel fibers cooperating with the first external layer or with the second external layer, the whole being made solid by means of at least a layer of thermofusible glue, disposed inside said first external layer and second external layer and in coordination with the corresponding layers of parallel fibers. |
