Sorry, I didn't get real specific did I? The pontoons folded onto the top of his trailer. He had built it with a flat roof so they would sit properly. I guess he built a taller area at the center hall for walking.
I didn't see any engines, but he did have a wooden closet at the rear that could house the motor. I saw some type of steering device underneath the rig but couldn't figure out what he mounted on it. It was not a rudder.
He told us that he runs on the rivers and canals in Ontario, Canada.
