Hot tub, meet boat
We’ve seen wood-burning hot tubs that float, but the HotTug takes that concept to a whole new level by adding an electric motor to the stern. Result: a rudimentary boat that lets you cruise down a river while soaking your bones.
Created by a Dutch inventor a few years ago, the HotTug is now for sale in the U.S. It's made from chestnut wood and fitted with glass-fiber-reinforced polyester. The stainless steel, wood-burning stove can heat 480 gallons of water in less than three hours.
There’s also a waterproof storage space, a swim ladder, a navigation light, and it'll accommodate up to eight people.
