ABSTRACT:
In a skate sail assembly of the type having a T-configured frame including a boom and a resiliently flexible mast detachably mounted thereon, and a generally sector-shaped sail supported in a taut condition by the frame, the boom has a U-shaped resilient portion intermediate its ends, which portion imparts flexibility to the boom in the longitudinal direction and additionally serves as a handle for the user. The flexibility imparted by the U-shaped resilient portion of the boom and the mast enables the device to be more easily assembled and dismantled, and is essential in order that the sail may function satisfactorily as an airfoil.
