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.
