The most important design aspect of a tiny house is the success of its interior layout. The tight quarters may look quaint on paper but in reality turn out to be claustrophobic. The need to stoop and to contort yourself to fit into the small spaces may lead to bumps on the head and cramps. Lack of storage may seem inspirational for those aspiring to minimize their earthly possessions, but inevitably results in clutter. Lack of private spaces may inspire greater intimacy short-term but lead to strained relations in the longer term. And so on.
The set of such problem to solve is even greater when designing a houseboat because of the need to compensate for the almost constant rocking motion in all but the most sheltered marinas and anchorages. Berths (beds) have to be oriented with the head pointing aft: cribs rock side to side and while having your feet bounce up and down is tolerable, having your head do the same generally isn’t. There can’t be any sharp corners, especially where your head or your knees and elbows might end up, and there have to be handholds within easy reach. Shelves and tables have to be fitted with fids to prevent items from rolling off. Dealing with the inevitable condensation is far more important on a boat due to its proximity to water. (Many sailboats will drip cold water on your head as you try to sleep.)
These problems are easily solved by paying a few million dollars for a megayacht, but our goal is to make living aboard an affordable, comfortable, competitive alternative to paying rent. Not only does this tiny house have to float, but it has to be mobile and move both under engine and under sail. The constraints that this imposes on its design are quite formidable. Consequently, only now, after several years of design effort, is it approaching the point where there are no conceptual problems that remain to be solved and construction planning can begin.
