My other obsession is inexpensive boating. Boating for everybody, something like that. Links on "Pittsburgh Inflatable Yacht Club" | Facebook
I've been navigating the rivers of pittsburgh in a 100 dollar blow up boat with a trolling engine. But I've been looking at the various four stroke motors as a possible solution for a sub 500 water craft. I think a pontoon design with one of these four strokes could make a lot of sense.
I'm sure someone here has done that already. It would be great to have a fold up boat that can be towed by motorbicycle then launched all by one person.
