Abstract

The invention relates to an airfoil sail structure (1) or "wingsail" mounted on a mast (7) of a boat (2), said structure (1) being characterized in that on said mast (7) are placed, from the bottom to the top, a base element (8), at least one intermediate modular element (4), and an upper modular element (5), said modular elements (4, 5, 8) having a rigid coupling structure with said mast (7) bow of the same, said at least one intermediate (4) and upper (5) modular element having a flexible structure extending from said mast (7) to aft, on said modular elements (4, 5, 8) being wrapped externally a single sail (3), said upper modular element being coupled to halyards (20) to hoist the sail (3) of the structure (1).
