ABSTRACT:
A resiliently flexible wishbone boom comprised of a pair of boom sections attached to the pivotal mast of a sailboard. A sail located between the boom sections is attached by its leading edge to the mast and at one location along its trailing edge to the outer end of the boom. The boom has flexible forward portions which enable the boom sections to be drawn closer together, thereby making the boom longer and applying increased outhaul tension on the sail which changes its overall curvature and aerodynamic efficiency.
