We have a few airboats on the river and no one likes them including many of the passengers! Its a good solution, but not for me. And, it's not the kind of experience I want to have with my grandkids.
I tried paddlelwheel, and even built a feathering sternwheeler prototype. I ran OK, but was VERY pitch sensitive, so I abandoned it.

> Go to an RC field when giant scale electric models are flying and you can evaluate the noise and have a pleasant Sunday afternoon watching the models fly. The grandkids will enjoy it, too.

> I'm looking for a shallow water propulsion system to connect to an electric motor to push a 14' boat upstream. Need about 6 mph.

> Right now I have a Torqeedo on a 12' johnboat, but the prop gets into the gravel bottom in the section of the Wabash River I motor with the grandkids. We need a simple, safe method of moving our boat, even if I have to build a boat and drive to do it.
