I am considering repurposing the hull form of River Rat 22 scow as a jack of all trades middleweight utility. I envision it as a homebuildable alternative to the huge v bow aluminum jon boats that are very common in many areas of the US.
The shape of the hull itself would be unchanged and the use of ply on frame construction would be retained.
the lines are from http://www.atkinboatplans.com/Oar/RiverRat.html
The changes I am considering are:
- Get rid of the huge cabin. Leave a head with some privacy. kitchen, beds, full roof: gone. Semi permanent tent optional.
- With the weight of the cabin gone, increase scantlings dramatically. The original fishy sounding 3/8 bottom and 1/4 inch topsides will both be replaced with 3/4 inch marine ply or good mdo. Oak frames possibly replaced with longleaf pine or clear douglas-fir for reasons of cost.
- Knowing it will rarely see open waters, and spend most of its time in fresh water and in or near harbors, an internal motor well may not be entirely necessary. To make more room inside the motor will be moved to the transom and a splash well used.
For now this is just a thought exercise, and I do not currently intend to build. If I ever build I would likely power with a 1960s era evinrude 18 for financial reasons, namely I got one off craigslist for my 21st birthday and I don't have enough money for a newer motor. If I had an unlimited budget I would likely try to find a Yamaha 40hp two stroke based on their popularity with commercial fishermen.
