ABSTRACT:
A spreader bar for use in connection with a harness worn by a sailboarder. The spreader bar is fixedly interconnected with the harness and includes a sheave adapted to engage a line affixed at its ends to one arm of the wishbone boom of a sailboard. The spreader bar allows the user to support his weight on the boom line with the sheave adapted to roll on the line in response to movement of the board sailor or the boom. The sheave is supported so as to be easily engaged and disengaged from the boom line.
