Abstract
A device for rigidly but removably attaching the boom assembly, or wishbone (46), of a sail-powered vehicle to the mast (14). The device includes a tubular mast sleeve (15) that is slit in front, receptacles (16) for the forward ends of the booms (36,38), and a mechanism that permits the mast sleeve to deform so as to grip the mast but resists any other deformation.
