A little boat my brother and I built , this one was actually based on a plan, from Herb McLeod, the OSS (one sheet skiff). This boat is made from only one sheet of 1/4 plywood and about 5 eight foot long 1x2's. The materials total about $20. It is surprisingly stable with only one person, I built one for myself after this and mounted oars and used it for fishing, and I've built a couple more since then but they're sold now.
