I've been fiddling around with designing a solo canoe for running some Ozark rivers. There isn't any real serious whitewater to negotiate, up to and including class 3. I'm looking for a canoe for only river running. Does anyone here have plans or know of anything available along these lines? I like to have existing lines to go off of when I design so I can have some ballpark references. I think I've settled on a construction method that can get me a tough canoe that can handle a lot of grounding and impacts, but we'll get into that later.
