A surface effects skimmer vehicle generates a downward air flow into a
tunnel under a main hull to lift the main hull off an adjacent surface,
and rearward air flows for thrust. The air flows are generated by ducted
fans or jet engines, and directed to the rear and/or down by controlling
the degree of opening of a Deflector Air Gate (DAG) on the bottom of the
main hull. The tunnel includes tunnel edges to contain the downward air
flow under the main hull for surface lubrication. The vehicle further
includes a rear portion with horizontal and vertical stabilizers to
provide air-craft like behavior.
