      Consider skin on frame constuction using 26 ounce double ply woven
      nylon skin. Quoting from "UMIAK An Illustrated Guide" by Skip Snaith:
      "The 26-ounce double-weave nylon skin on Tim's boat was incredibly
      tough; you could hit it with the claw end of a hammer as hard as you
      liked, and the hammer would bounce back."

      Skin on frame can produce very light boats. Platt Monfort's Geodesic
      Aerolight boats are incredibly light, but probably not strong enough
      for the Watertribe Challenge. Up the scantlings a bit, with the frame
      lashed rather than glued to preserve flexibility, and use a much
      tougher skin and you'd end up with a light, resilient boat.
