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.

A gas-cushion vehicle, provided with sidewalls, comprising: hydrodynamic means for generating lift forces; the sidewalls defining recesses for receiving the hydrodynamic means and having bottom portions with downwardly and inwardly sloping surfaces, each of the hydrodynamic means having a bottom of corresponding form; and, means for extending the hydrodynamic means from said recesses into operable positions below the sidewalls and for retracting the hydrodynamic means into inoperative positions within the recesses, whereby the hydrodynamic means enclose said recesses and are substantially flush with the bottom portions of the sidewalls.
