Looking for the perfect mobile party? Head to Seattle, where the world's first (and only) Hot Tub Boats are produced.

The name says it all—these boats hold six adults, a built-in MP3 stereo, and a 24-volt electric motor. You won't go fast, but you will relax in a whirlpool bath and enjoy an ever-changing view.The boat doesn't have a wheel, instead employing a joystick, but will not fail to steer passengers toward fun.  In fact, the specs remain as when we first tipped our hat to this brilliant invention

What's new? The Hot Tub Boat is making its full debut at the Seattle Boat Show this week.
