Trilobis 65 is a semi-submerged dwelling environment. Reaching 20 metres in length designed by Giancarlo Zema for habitation by six people at sea. Giancarlo Zema, Italian Naval architect is featured in the  web site for his unique creative sense of naval design. Underwater Vehicles inc. is pleased to interview Giancarlo and welcomes any additional questions from web readers.The main characteristics of his designs are his flowing lines and elegant use of high quality materials. Trilobis 65 is ideal for living in bays, atolls and maritime parks. The main aim of the project is to allow anyone to live in a unique environment through a self sufficient, non-polluting dwelling cell in unison with their ocean surroundings. Trilobis 65 has been designed on four separate levels connected by a spiraling staircase.The top level is 3.5 metres above 
sea level. The next level is at 1.4 metres above sea level and hosts the daylight zone with all services and allowing outdoor access. The third level is situated at 0.8 metre below sea level, semi-submerged, and is devoted to the night-time zone. At 3.0 metres below sea level, totally submerged, there is the underwater observation bulb, an intimate and mediative place.

The shape of Trilobis 65 allows the annular aggregation of more 
modular units, creating island colonies.This special project refers to the Trilobiti, little creatures that lived in the sea 500 milion years ago. Life, say the experts, began in the sea. And if the way we spend our vacations is an accurate indicator, there are few things we enjoy more than revisiting our submerged roots. Cavorting with dolphins, badgering sharks from the safety of steel cages and photographing exotic fish through the portholes of tourist submarines fascinates landlubbers from Prague to Peoria.

For those who find these forays into Neptune’s realm too brief, Italian naval architect Giancarlo Zema has the perfect dream home, the Trilobis 65. Part yacht and part submarine, it could convince Capt. Nemo to hang a “for sale” sign on the Nautilus. “The main aim of the project is to allow anyone to live in a unique environment through a self-sufficient, nonpolluting dwelling that exists in unison with their ocean surrounding,” Zema tells POPULAR MECHANICS.

At first glance, the Trilobis looks as if it would be more at home soaring into the sky than plying the waters of atolls, bays and maritime parks. Looking at a computer image of the bow conjures up visions of the flying saucers in 1950s science fiction films. The Trilobis’s blueprints, however, reveal a nautical heritage that reaches back to the humble dugout while simultaneously embracing 21st century technologies that include high-strength composites and nonpolluting hydrogen fuels.

Circular Living – Perhaps the most striking feature of Zema’s design is one that reflects his willing recognition of the great unspoken truth about luxury yachts. Powerful engines and sleek hulls aside, these vessels typically stick close to home. Acknowledging the fact that well-heeled mariners often prefer to keep their floating palaces moored inches from the dock, Zema also designed a special type of marina that will enable like-minded Trilobis owners to create their own floating villages.

The traditional rectangular dock will disappear, to be replaced by a roughly 60-ft.-dia. circular island in the shape of a 6-tooth gear, into which individual yachts fit like pieces of a jigsaw puzzle.Stepping off the floating island, yachtsmen will ascend a few steps and find themselves on an expansive circular deck. At this level, the Trilobis resembles a deviled egg, measuring about 65 ft. from stem to stern and 42 ft. from port to starboard. Zema has divided the interior space into four functionally different levels, connected by a spiral stairway that runs through the yacht’s centerline. The top of the stairway opens onto the driving deck. Housing the helm, communications equipment and navigation gear, it offers the best view of the sea from its elevation of about 11 ft. above the waterline.

The space is dominated by a massive glass wall that begins above the stairway and arcs gently over the forward seating area before disappearing into the deck below. Ordinarily, so large an expanse of glass would pose a heating problem, but this is no ordinary window. It is a sandwich of two layers of tempered glass and an electrolyte with a very unusual property. With the turn of a dial, you can change the voltage flowing through the electrolyte material, which is encased between the panes, altering the tint of the window or blacking it out entirely. Power for the windows and the ship’s electrical systems comes from photovoltaic panels, manufactured by Siemens, that are integrated into a foam-reinforced fiberglass skin. At night and on cloudy days, power comes from batteries, with an inverter converting DC into AC for low-loss power distribution. Descending from the top to the craft’s third level, yachtsmen will enter what Zema calls the day area. Its use of space is a reminder that spherical structures are more efficient than rectangular ones.

As with the space above it, the day area is surrounded by self-shading glass, offering a panoramic view from the gourmet kitchen, formal dining area and three seating groups. On this level, the spiral stairway serves a secondary function of separating interior and exterior spaces. Sliding glass doors fully retract, opening onto a teak deck.Returning inside and following the stairway down one more flight leads to what is known as the night zone. The Trilobis sleeps six, with a premium on privacy. The design calls for two single and two double bedrooms, each with a private bathroom. With the deck at this level beginning 3 ft. below the waterline, the wraparound window cuts off at eye level.This level also houses the yacht’s propulsion system, which consists of two electric motors. Each is rated at about 300 hp. They are powered by hydrogen-fed Ballard fuel cells. The hydrogen for the fuel cells will be stored in a pair of 240-gal. tanks located just aft of the single bedrooms.

The fuel supply is not intended for ocean crossings, but to be sufficient for moving the yacht to nearby reefs to explore seasonal changes in marine life and catch a true fish-eyes view of unusual migrating species. The most distinctive feature of the Trilobis is its fully submerged first level, the observation bulb. Like the driving deck and day area above, it offers a commanding and unobstructed view of the sea. Only here, that view begins 10 ft. below the waterline. This is the smallest of the levels, just big enough for six chairs. Built to the same technical standards as tourist submarines, it is a thick glass enclosure that provides a 360° view. So that this area can be used when there’s no sunlight, the Trilobis has a ring of 200-watt spotlights, angled away from the observation bulb, to illuminate any sea life swimming directly in front of the viewers. The second set of spotlights, placed just below the deck level, lights the reefs below.

Zema is several years from building the first Trilobis. Most likely, it will be constructed in Vancouver, British Columbia, where he has set up an exclusive marketing relationship with Underwater Vehicles Inc. The location may seem like an unusual choice, but the region has the two essential ingredients needed to make the Trilobis project a success. The first is its wealth of small inlets and bays. The second is a pool of wealthy yacht owners, one of whom may be willing to invest the $4 million to $5 million it will take to launch yachting into the 21st century.
