ABSTRACT:
A marine craft includes a floating body, elements adapted to generate a center-board effect, in particular a center-board projecting beneath the floating body, and a rigging. The rigging includes at least a directional kite forming a canopy and a series of sheets controlling the canopy linked to the craft, the series of sheets including a main sheet and two directional sheets, and a substantially punctiform member for guiding the main sheet and for applying tractive force of the sheet on the craft. The rigging further includes elements for spatial orientation of the axis of the resultant elements the tractive force exerted by the rigging on the craft so as to almost completely eliminate the list whatever the moving speed of the craft and with the guiding and force-applying member located above the water level.
