Book excerpt: A step-by-step instruction manual on how to build a lightweight 'environmentally-friendly' boat with recyclable resources. The boats simply fold up from ¼” thick cardboard obtaining their strength from the geometry of the component parts. The boats are 8-feet long, weigh about 25-pounds, and can accommodate a 250-pound person without risking structural damage. Each boat is constructed with 21-pieces of cardboard that are used to make 7-component parts. The 7 parts are assembled together with 'environmentally-friendly' contact cement and paper drywall tape. Once assembled the boats are sealed with an 'environmentally-friendly' water-based waterproof coating. No special tools are required and they are very simple to build. All of the materials used to build a boat are typically found at 'do-it-yourself' home improvement stores. The boats can be outfitted with 12-volt electric fishing motors, although they are typically propelled with traditional Kayak style paddles.
