As if enjoying a leisurely cruise across a lake wasn't relaxing enough, a Seattle company has found a way to take it to a whole new level by cramming a 2.4m long hot tub inside a 5m boat. This is synergy at its finest, people.
When the hot tub is completely filled with 40C water — courtesy of a diesel-powered boiler — the boat weighs in at 950kg, but it still manages to float about 50cm above the waterline. And a steerable electric motor controlled by a small joystick takes care of propulsion, bringing the craft to a top speed of about 8km/h. So it's obviously designed for leisurely trolling, made all the more enjoyable by its 50W sound system and four separate coolers for your libations. If there was ever a good reason to mortgage your house to raise $US42,000, this is it.
