I'd also much prefer to stay in shallow waters with the thing. At that height/width-ratio, it's probably not really seaworthy (although probably not
much worse than any other motorboat about that size - smallish motorboats are not the place to have fun in heavy weather, as opposed to smallish sailboats which have the capability to stabilize themselves to some degree when the sea gets rough). Make that thing a
submarine, and I'm all set to buy one. Umm...if somebody donates me the cash, that is.
