AbstractA sea-going craft has a main central body with two wings affixed to the body and extending horizontally away to either side. A catamaran-type hull is attached to each wing end, and provides flotation. The rearward edge of each wing is generally closer to the water than the forward edge when the craft is under power, thus adding lift due to the ground-effect phenomenon. A hydrofoil is affixed to each hull and extends downwardly, and a third hydrofoil is affixed to the central body, extending downwardly. The craft includes propulsion apparatus.
