Bateau.com has a free plan on their website called the cheap canoe. You build it with 2 sheets of plywood, some epoxy and a little fiberglass cloth. Super simple and very inexpensive to build. You can also go whole hog and buy marine epoxy, and glass cloth the whole boat, but the price really starts to climb then. I did one with epoxy from an auto body shop, some inexpensive 6" wide 10oz. fiberglass cloth strips to close the joint between the bottom and sides, then just painted it with exterior paint. You can build them for under $100, and only a few(very few) hours of your time. Most people can knock them out on a Saturday, and use them on Sunday. And by the way, they are actually more of a pirogue, and are STABLE!
