Abstract
A hull for a personal watercraft includes a compression-molded hull body. A main portion of the hull body includes a thermoplastic material embedded with non-directional chopped glass fibers. The main portion extends along an entirety of the length and of the width of the hull body. Port and starboard portions of the hull body include the thermoplastic material embedded with directional glass fibers. The directional glass fibers include longitudinally-oriented glass fibers. A majority of the longitudinally-oriented glass fibers have a length at least ten times greater than a mean length of the chopped glass fibers. The port and starboard portions extend vertically from proximate an upper edge of the hull towards a keel, and longitudinally along at least 50% of the length of the hull body.
