Folding Kayak - By Jess E. Rathbun. This kayak folds like a book. You can carry a fleet of these lightweight craft on top of your car. It's not fast, it's not roomy and you won't find many practical uses for such an outlandish craft. In fact. this center folding kayak has only one feature: It's fun. It's also inexpensive so you can afford to make one for every member of your family. And you can tote a whole fleet on top of your car. Construction is unorthodox, instead of using screws, nails or other common fasteners. you tape the boat together with canvas and conlact cement. No metal parts are required.
