Abstract
A human body sail assembly including a rotatable mast with upper and lower horizontal sail braces or booms that swing with the mast. The sail is tensioned by the braces and can be locked in a desired angular position by user-operated frusto-conical mating gearing coaxial with the mast. The braces can separate from the mast for safety if the user falls, and the sail can be collapsed in a compact envelope by swinging the braces toward one another adjacent the skater's back. The braces are identical and removably mounted in pivot assemblies carried by the mast so different length braces can be used with the same pivot assemblies. The pivot assemblies are defined by a large disc member carried by the mast and a brace socket with spaced circular plates indexably engaging the sides of the disc.
