ABSTRACT:
The invention is an improvement in the construction of the sailboard portion of windsurfers wherein the usual hard-foam slab hull typical of surfboard construction is replaced by a slab of soft foam, the only rigid structure of the entire board being a pair of closely spaced fiberglass stringers longitudinally extended along the midline of the board, and mounts for the mast, daggerboard and fin, which mounts are sandwiched between the two longitudinal stringers which are embedded centrally in the soft foam slab.
