Remember the Hot Tug? Get your mind out of the gutter, it is a small boat with a built in stove/hot tub. Well it now has a more grown up looking friend built by two Seattle, WA marine carpenters. This boat is powered by an electric motor while the heat for the hot tub is created from an integrated diesel-powered boiler. The boat only drafts 20-inches, even when filled with 2,100 lbs of water and six adults. Pretty cool.
