The HotTug is one of the more awesome inventions we?ve seen in a while.

It seats six to eight people, and heats the water up to 101 degrees F with a wood stove onboard. It sails quietly with an integrated 2.4 KW MinnKota engine, and it can also accommodate an outboard engine if you?ve really got somewhere to be.

With a top speed of about 3mph when full of 475 gallons of water, you won?t set any speed records. But who cares? You?re already in a hot tub!

The boat/tub is made from wood with common fiberglass overlay construction. This popular method for homemade boats may inspire some do-it-yourself builders to consider one of these as a backyard project.

But for most people, purchasing a pre-made HotTug would make a LOT more sense. And good news ? the product, originally launched in Europe in 2012, is now available in the United States.

While it?s probably not a practical item for most people, you can rent one in Rotterdam, London, Z?rich or Copenhagen. The experience of hot-tubbing your way through an iconic city might alone be worth a trip.
