A board for gliding over snow, more particularly for children, includes a structure made of just one homogeneous material of an injected thermoplastic polymer, two metal side edges with wings, bordering the bottom surface forming the gliding surface. At least one aft cavity can be located within the outer skin and substantially aft of the forward cavity. A mainsail mast and a mizzen shroud slide transversely within limits to promote sail proximity and to achieve increased speed via an improved draft. Either major surface of the blanket may have a facing bonded thereto with one or more perforated lines or overlapping tabs in the facing permitting the facing to be separated by hand at each series of cuts and separable connectors.
