Abstract
A sail shaping arrangement for a sailing craft as a sailboard is described, the arrangement associated with each of the sail battens. The shaping arrangement includes a pair of flexible fingers extending over and past each batten to straddle the mast within the mast sleeve. As the sail swifts to either leeward position, one end of the windward finger is bent to form a knee, one side of the bent end acting against the mast to be restrained thereby stabilizing the sail in that condition and also tenching to arch the batten and thus act as a camber inducer. The flexible fingers are preferably flat plastic pieces installed in pockets sewn opposite each other onto either side of the sail over the batten pockets.
