This is a hand made hovercraft. I was surprised to feel like these things fly rather then the feeling you would normally get from a boat. The whole thing is basically a shett and a lawn mower engine... One of these days, I will make me one of them. http://www.hovercraft.com/content/index.php sells blue prints to build your own in 300 hours or less. That was a nice sunny day on the mississipi like the good old days!
