Depending on where you fish, a small like pram can be an advantage. I built a small pram (9' 6' x 52' with three planks to the side and flat bottomed) when I was living in Missoula, Montana, and floated quite a few local rivers there without difficulty. But I was careful about what sections that I floated and when. The big advantage was that I could roll it from the truck to the river on transome mounted wheels, and get on the river for an hour or two by myself. I built another flyfishing pram a few years ago, after moving to North Idaho. It is primarily a lake boat, for one or two fishers, that can also be used in rivers. It is my own design, 9' 7" x 51" with one plank sides and a V bottom. It has a very shallow v in the middle of the boat to give it good initial stability for standing (calm water only), but deeper at each for punching through a chop in lakes. I put narrow wheels on the transome so that the boat will track in lakes with wheels down, and spin in rivers with wheels up. It rows very well for a short boat and rides in the pickup bed. I don't have plans, but I do have photos if anyone is interested. I'm also thinking of selling this one, as I have built a number of other boats and am trying to clear a bit more space in the garadge.
