From the cold reaches of the Netherlands, we get the HotTug, a wood-fired hot tub you can take out on the water:
It is ideal for carefree fun and relaxation on the water, moving or stationary, ready to take you to idyllic spots for a visit or a swim. Frank de Bruyn: “It’s much more than a boat, it’s a vessel with different options. When the tug is filled, there is only a narrow rim between you and the water, making you feel at one with your surroundings.”
