Abstract
A watercraft combining the physical and hydrodynamic features of a catama, a hydrofoil, and a rigid sidewall air cushion vehicle that might be considered a triple hybrid (TRIBRID). The TRIBRID is intended to operate as a multi-modal vehicle in the approximate speed range of 0-100 knots. The vehicle from at rest to operational speed, obtains its lift at first from 100% buoyancy of catamaran hulls, then from dynamic lift of hydrofoils, and finally from powered aerostatic lift from a captured air cushion. A combination of two or all lift modes may be used through speed changes and at intermediate speeds.
