ABSTRACT:
Presented in an advanced high speed air cushioned marine vehicle that incorporates retractable land drives for operation over beaches or other hard surfaces. The land drives retract into air cushion hull recesses when the vehicle is waterborne so as not to add water resistance at high waterborne speeds. Power for water propulsion as well as land drive is normally supplied from the same propulsor motor(s) for simplicity. Land drives may incorporate tracks, tires, or other land contact mechanisms.
