Simmons Sea Skiff
No Problem,
The project is far, far beyond my present set of skills, tools, time, and budget, but I have been intrigued by the prospects of building a Simmons Sea Skiff for several years now. The SSS is a lapstrake hull made with strips of plywood with a motor well and can be built with practically unlimited options such as center console, glassed bottom, etc. The plans are available from a museum in Wilmington, NC and it's simple to home in on them via google. You'll see an 18' design which I would imagine could be easily rowed and which would also be easily powered with a small outboard. I think 25hp is the max recommended for the 18.
I'd probably choose a much simpler design for the first project, see how the grandson's interest holds out, and look at a more complex, expensive, and longer-term project, such as the SSS, for the next one.
Good luck with your project. Please post once you decide the route to take and get under way.
