A lot of people live near a lake but not on the water, so they either have to carry their boat or use a trailer. In a town like ours it has a public boat launch so there is no room to park a trailer. The solution is to design a boat that you can drive there and go right into the water. In my design the tires are built into the paddle wheel and the front tire is built into the steering rudder. The original design was a chain design then I added a shaft design that you could add an electric motor and battery. The final design was a high bred that the peddles would only be used to drive the electric motor or recharge the battery.

The steering wheel was replaced by handle that you could fold forward and pull it like a wagon.
