Re: duck boat idea
I made one from one 4' x 8' plywood, with a 45* sloped bow and 24" sides and stern. Worried about stability, I placed the deck on a log and weighted the sides to get a bow to it. Sides were about 2" lower than the center line. It was stable enough to use on the Yukon for a year, until we moved back South. Among other duties, it carried a yearling moose, my 8 yo son, our camping gear and me about 8 miles back up the Yukon to Tanana.
