A sailing rig for driving a vessel which permits efficient operation at headings very close to the wind, comprising a plurality of jib sails arranged so that the camber of the jibs is between 12 and 25%, preferably between 14% and 20%, most preferably between 14.5% and 18% when closehauled, and preferably the sheeting angle for the jibs is such that a continuation of the line of sheeting force intersects the luff of the jib at a point above about 65-80% of its length.
