Floating House by Friday. Traveling at a speed of three knots, it is equipped with two small outboard motors and its length can be extended to contain up to three bedrooms. When charged, the house is self-sufficient for at least seven days, providing enough energy for those onboard. The design includes a fully equipped kitchen, heat pump and AC generator, a wine cellar, as well as a barbecue on the upper terrace. The extensive list of amenities means that the house can be used as a base camp for a range of watersports, or simply as a weekend getaway.
Now, if we could make such a thing tolerant of slightly rougher seas and get some costal municipalities to change their ways, this might make a fine full-timer water RV.
No, forget that. A proper full-time water RV would be a tug.
I could still think of many bodies of water this would do nicely in.
