bACK TO THE sEA

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," tells Zema . 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.
