ABSTRACT OF THE DISCLOSURE A novel rigging for a sailboat is disclosed in which the mainsail is mounted between a luff boom and a foot boom, the luff boom being attached to the top of the mast by a fitting that allows rotation at least about a vertical axis parallel to the mast and about a tilt axis normal to the mast such that the luff boom can tilt out of the vertical. The fitting is joined to the luff boom at a pivot point above the center of effort of the sail, and not necessarily at its head. A tack sheet and a clew sheet restrict the tilt of the luff boom and its rotation around the mast. A jib sail, too, may be tiltably mounted by attaching it to a luff boom which is suspended at its head from a high point on the mast. The mast may be retractable or extendable and either luff boom may be given a streamlined cross section.
