A floathouse is a new kind of floating home designed to do one thing better than any other floating structure: to stay in one place, comfortably and securely, on the ocean.
Ventive SeaTech has pioneered new production processes that allow us to create incredibly strong tubular structures reinforced with a technology called filament winding, invented in the 1960's for the aerospace industry, combined with geopolymer cement to create incredibly strong, large-diameter tubes that are impervious to seawater and can withstand heavy wave activity.
The secret to the high wave-stability of the floathouse is the round hull-shape, very unlike a typical boat's hull which is deep and narrow, and the ability to connect two or more of the structures together.
Two can be hinged together using pantograph arms, adding to their stability dramatically. When a wave comes by, pantograph technology will keep the floathouses very horizontal, rocking side to side very little, even as it slowly rises and falls on the waves. Occupants should experience this more as a gentle rise or falling sensation, a bit like riding on an elevator, with much less of the rapid side to side rocking motion that makes people seasick on a typical boat.
This anti-rocking mechanism is also aided by technology called a drogue, or a water-parachute, which is able to strongly resist rapid vertical-movement and rocking, further moderating any water-induced motion, increasing comfort and safety for home-owners.
The third thing making a floathouse much more stable than a typical sailboat is its heavy weight. Being made of inexpensive and environmentally-friendly geopolymer cement, the structure can be made much heavier than a typical boat of the same length. Waves therefore cannot lift it as easily, or toss it around like they can a sailboat, which makes a floathouse much less responsive to wave conditions in general. A floathouse can weigh as much as eight times more than a sailboat of the same length, and this is very good for its stability and comfort.
One Structure, Many Configurations
We offer the Floathouse shell in multiple configurations to suit a variety of needs. Each could be used in a variety of scenarios. Some, like the vertical Spar, are suitable for a rough, deep-sea environment, while others are more suitable for a calm marina setting with protected waters.
We currently plan the following products:
Limited pre-orders are available. Checkout our product overview for more information.
A Brief Look Into the Single Family Home
The standard Floathouse shell can be adapted to any number of private or commercial uses depending on how the interior is finished, but we expect one popular application to be the single family home that an average family of 4-5 people could feel quite comfortable in. Rather than seeing these structures as pleasure craft, we are building them to be your primary home year-round, and to last for decades without significant maintenance.
Here we see the basic shell, finished as a single-family home:
Shell - single family home
The Floathouse structure is approximately 80-feet long, 24-feet wide, and 24-feet high. It has 2 floors, giving a total floor-space of about 2300 square feet.
Windows on all sides offer generous views in every direction, and skylights illuminate the interiors in all rooms with natural sunlight. The structure's gently curving walls and ceilings are pleasing to the eye and give it an organic feeling.
We've created a sample floor-plan for a single family, but other designs are possible:
Top floor - single family home
The single family floathouse has two entrances, a front and back door. The front entrance gives you access to the foyer, which has a second security door and is designed as a water-tight space that will prevent water from entering the rest of the Floathouse while the front-door is open. Also makes for a convenient coat-room and shoe-storage room.
The foyer leads into the living room and kitchen on either side, as well as downstairs-access.
Next to the living room are the dining room and kitchen. The kitchen has ample countertop space, cabinet space, a walk in pantry, room for a full-size refrigerator and stove, and a large island.
Basement - single family home
The decisions about how to lay-out the downstairs makes a number of important compromises. The stairs leave you in a generous garage space, with room for project space or a small workshop, or even as a laundry room. The garage has its own half-bath with a toilet and sink.
The other doors provide access to multiple water tight rooms separated by bulkheads. These rooms function as a safety feature in case of damage to the hull which causes a water leak. The water will be well-contained in the room where the leak occurs and will prevent the floathouse from sinking. Any two of these compartments can keep the entire structure afloat, giving more than ample safety-margin. And by storing the waste-water tanks in the center of the room, we improve the balance of the structure and ensure that there is always access to the hull in case repairs are ever needed.
These spare rooms could be used for any number of things, from quiet bedrooms to offices, storage rooms or home-aquaculture. We leave that to your imagination and ingenuity.
In the center are the gray and blackwater storage tanks. The tanks will be able to hold up to a month of wastewater for an average family. On the other end of the basement is the engine room. This will be used for an optional-engine and any other heavy machinery you may require. Otherwise it becomes available space.
The engine room also provides access to the power-center which contains space for electrical breaker boxes, electrical-inverters, and battery power storage. We have designed this room to accommodate arrays of Tesla Powerwall-2's or lead acid batteries. Two to three Tesla Powerwall-2's should be enough to provide an average house with all the power they need for a full day, but this room contains enough space for 10 such batteries. Batteries can be recharged via a generator, solar panels, or plugin power.
