Abstract
A 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.
Claims8
A sea-going craft comprising:
- a main central body,
- two wings affixed to said body and extending generally horizontally away therefrom to either side,
- a catamaran-type hull affixed to each wing remote from the central body, the hulls being adapted to provide flotation,
- each wing having a forward edge and a rearward edge, each rearward edge extending obliquely and smoothly from the respective catamaran-type hull to a rearward location behind the central body, each rearward edge further being substantially closer to the water than the forward edge when the craft is under power, whereby the wings can exhibit the wing-in-ground-effect to produce ram lift,
- a hydrofoil affixed to each hull and extending downwardly therefrom, and a third hydrofoil affixed to the central body and extending downwardly therefrom,
- and means for propelling the craft.
