The present invention with the designation "rig for a sailboard" relates to the rigging required for a sailboard, consisting of a luff mast, a wishbone boom fastened to the luff mast, and a sail guided with its luff on the luff mast and stretched with its top and bottom luff corner, a clew and a head corner between mast and wishbone boom. In contrast to the known rig of M. Darby or even to the Swiss rig, the rig has a sail shape which is fluidically more advantageous and better utilises the wind conditions and the wind speed over water, the air largely flowing in a laminar manner around the entire sail profile and an enlarged sail area at the head being utilised. In this arrangement, the other parts of the rig, in particular the length of the luff mast, are not larger than the parts normally used hitherto. Here, the sail is changed into a rectangular shape enlarging the top area of the sail up to a top edge and reducing the bottom area of the sail at the leech. The centre of gravity of the surface of the sail shape is shifted towards the luff mast and up towards the top-edge mast. Furthermore, the luff mast is extended via a mast knee and a top-edge mast in such a way that the sail guided on the luff mast is freely suspended at the top luff corner and the corner points at the leech between wishbone boom and top-edge mast.
