Here's a molded plastic kayak that has a large crack aft of the cockpit. The kayak measures 13 feet long and has a beam of 23 inches. I don't know if it is repairable, but if not, then the hull could possibly be used as a mold. Alternatively, one could possibly cut out the entire damaged section, making a larger cockpit opening. The rest of the hull is OK, but dirty from being stored outside. One of the internal footrests is missing. The molded plastic seat is intact. Free if you come pick it up.
