An amphibious trailer?

While perusing a site of tiny homes, I came across a listing for the Sealander, a small pull trailer with a soft top that can be used as a boat (of sorts) - kind goofy, but it might be fun!

Doesn't look real stable, but man!! think of the possibilities.  Needs a little all terrain drive motor too,

No bow on it, so it is going to plow like an SOB.

The military 1/4 ton trailers are designed to be water tight, every year at Tower Park Marina when they have a military vehicle get together they used to have 1/4 ton trailer races.  I think they used rifle stocks for paddles.
