Abstract
A sidewall gas-cushion vehicle is provided with hydrofoils carried in recesses defined by the sidewalls and capable of being extended into an operable position or of being retracted into an inoperative position. The foils may be used to generate lift forces and/or to counter unwanted movements of the vehicle, such as heave, roll and pitching motions. The lift forces can be made positive or negative.
