Typically when a boat fills with water you start praying and grabbing the life vests. What is not normal is to crack open a bottle of bubbly, get your trunks on, and kick back and relax party style. With the HotTug ($21,000) you can relax in your very own hot tub, but more than that you can also navigate your local waterway while you´re at it. This is the first floating/sailing wood burning stove hot tub and lets you casually motor around a lake or canal thanks to a built in electric motor. Silent running helps the relaxing atmosphere, while the burning stove is stowed in the front away from your legs.
