Do you have a plain old and ordinary hot tub? Why not make it float and navigate the seas with it. Yes, you heard it right. The HotTug is a motor-driven wood-fired hot tub for you and 4 of your buddies to enjoy. It’s technically a boat and is built from wood with polyester fiber. Simply fill the inner section with water and you are ready for some serious fun. The HotTug features a stainless-steel wood stove which has a single wall pipe to effectively heat the water you will be lounging in. The HotTug has a built-in motor unit of 2.4 KW or you can attached an outboard motor for maximum maneuverability. The HotTug can hold up to 2000 liters of water and the wood stove can warm the water up to 8 degrees per hour. On average, it takes about 3 hours before the water is 38 degrees Celsius (100 degrees Fahrenheit). The best way to empty the water inside the tug boat is by using a submersible pump that can empty it in approximately 20 minutes. This is definitely one the most unique watercraft we’ve seen in a while.
