ABSTRACT:
A sailing rig which comprises a rigid airfoil, with intakes on either side of its front. Air is drawn through the leeward intake into a front compartment, then by fan to a pressurized rear compartment, where it exits via a rearwardly directed jet nozzle on the airfoil's trailing edge. The airfoil may have an articulated jib and a pivotable jet nozzle.
