Is it A House, Or Boat?

                            Is your Eco-Sea Cottage a house . . . or a boat?      

Yes  . . .  and  yes.  

You see . . .  it's

HOUSE — The “cottage” portion of each ESC definitely qualifies as a house. In fact, the enclosed (“cottage”) portion of each ESC is built by the same nationally-established home builder that created the impressive, custom-built, million-dollar homes featured in the 2010 and 2011 season finales of ABC television’s “Extreme Makeover: Home Edition.”

However, the Eco-Sea Cottages are not an example of simply attaching a “plain” house onto a pair of catamaran hulls and then claiming, “It’s a boat!” Each house-portion of each Eco-Sea Cottage is custom-built, sized, and “marinized” to particular specifications, so that it’s worthy of serving safely and long-term as a comfortable floating home. How so?

  • Trusses & joists beneath each ‘cottage’ (which are designed to lay across the two hulls), are larger and more numerous than those typically specified for a home placed on a land-based foundation — and they’re more securely fastened, and specially treated for a marine environment.
  • The walls of the main-level of our 2-story Cottage portion are built with added strength – wall frames, for example, are 2x6s, rather than the typical 2x4s used for similar-size, “stick-built,” land-based homes. (Which then allows for up to 50% more insulation, too.)
  • The underside of each Cottage’s main floor is insulated with water-proof, aluminum-clad, "double-bubble" radiant insulation. Far better than, say, that “Pink Panther” material that loses its insulating qualities the first time it gets wet and compresses. 
  • Pressure foam, or closed-cell foam (non-moisture absorbing), is used around plumbing fittings for thermal and acoustic insulation.
  • The plumbing, tankage, four bilge pumps, and accompanying 12-volt electrical system are designed for the purposes of a vessel/floating home.
  • The cottage portion of your Eco-Sea Cottage is built indoors, and with greater efficiency than the standard, “stick-built” (piece-by-piece) construction processes used by most other floating-home builders.

The latter build the house-portion of their houseboats outdoors, on top of the hull. They do so with a labor-intensive (i.e., more costly), “stick-by-stick” process. By comparison, our ESC builders  — working entirely indoors — first construct multiple floor-and-wall systems, ceiling-and-roof units, multiple window-and-door frames separate from the two catamaran hulls. So, while “stick-built” units are subject to rain, mist and night-dew during their creation, your ESC  benefits from protective temperature and moisture control. Without that protection, “stick-built” homes can suffer, during construction, from fungus-or-mold growth within their floors or walls . . . which may not become detectable until well after the new owner has moved in.

In addition, the controlled conditions in our “cottage-construction” facilities give you better/tighter fitting walls, joists, floors and ceilings. This controlled construction setting also results in less wasted materials, and a faster, more efficient build time — all of which results in a "greener" construction process, not to mention a lower purchase price for you .

BOAT — The Eco-Sea Cottages’ metal, catamaran hulls, constructed by a professional boat-building yard in Washington state (which also builds high-spec aluminum vessels for the U.S. Navy), are rugged and sturdy. These aluminum hulls are protected by multiple anodes; by carefully applied epoxy and antifouling paints; and by a quality, galvanic isolator or insulation transformer.

Each ESC is assigned a lifetime, 12-digit Coast Guard identification number, etched into the hulls, just like those required for the finest megayachts.  Eleven, big (12-inch) cleats are welded in strategic locations around your catamaran hulls, affording excellent attachments either for towing, or for securing dock lines to your Eco-Sea Cottage. As an option, twin motors, a steering helm, and Coast Guard running lights are available.

         We also fabricate a big, 5-inch deep rub-rail right into the aluminum, along the full length of the outer side of each hull. So, even in heavy winds or strong currents, your Eco-Sea Cottage is well protected alongside a dock or pier.

         If you choose to have engines included, we weld on immensely strong motor brackets, one per hull.
