Innespace is a project started in 1998 by Rob Innes (right) and Dan Piazza (left), who built the watercraft themselves.
"I do all the shaping and composite work, and Dan does all the machining and metal fabricating," Innes said in an e-mail.
The single-seat Sweet Virgin Angel (right) was completed in 2001. A two-seater, the Sea Breacher (left), has been float-tested but still needs some work before it hits the demo circuit in 2007.
For the designs, Innespace drew on the work of inventor Thomas Rowe, crediting his Noland 1 craft--a "variable attitude submersible hydrofoil" (VASH)---as the first lighter-than-water vehicle to move beneath the waves as if it were flying.
Rowe, whose work dates back some two decades, is separately working on a project that he calls the "bionic dolphin."
