I've just recently completed a new kayak after a few years inactivity. The design is a hard-chine Iqyax (CNM-12212) that I built based on a simplified version of George Dyson's method utilizing aluminum stringers with plywood cross-sections. The skin is 8oz nylon coated with several coats of neoprene/hypalon.
