Don & friends (Rege, Bill, Jimmy, and Molly Cat) show how to build the 10' long, Robert Morris-inspired recovery-style kayak known as the "Toibote". From computer to finished kayak, this little play boat is easy to build, and a blast to paddle. Check out my "Building Skin-on-frame Boats" by Robert Morris, and the website at http://www.arctickayaks.com/Lines/LinesNorthAlaskaRetrievalUMN-N.pdf if you'd like to build a kayak like this.
