A sailing yacht having a hull and a sectional mast holding a sail, is equipped with a canard rudder and two rolling keels. Each rolling keel has a ballast container. A three point wing system is formed by wings carried by the canard rudder and by the two rolling keels for producing buoyancy, for steering, and for stabilizing. Thus, the three point wing system has a fore wing (9) forming an end wing of the canard rudder and two aft wings (11, 11′) forming end wings of the rolling keels (10, 10′). The rolling keels (10, 10′) are tiltable about rotational axes extending above the water line approximately in parallel to the hull axis, whereby the rolling keels (10, 10′) are normally above the water line and only the long end (14, 14′) of the wing (11, 11′) dips into the water, so that the end disk wing (15) functions as a lift producing surface. The ballast is shiftable between two ballast containers 17, 17′.

A sailing yacht, comprising a hull with a bow and a stern, a mast mounted on said yacht for holding a sail, canard rudder means secured to said hull near said bow, two rolling keels each hinged to one side of said hull rearwardly of said canard rudder, a first wing means secured as an end wing to said canard rudder, second wing means secured to one rolling keel, third wing means secured to the other rolling keel, said first, second, and third wing means forming a three point wing system for producing buoyancy, for steering, and for stabilizing, said second and third wing means extending approximately perpendicularly from said rolling keels, each of said second and third wing means comprising a long wing section and a short wing section opposite said long wing section, said long wing section extending approximately downwardly when the respective rolling keel is tilted laterally outwardly, each long wing section comprising a wing end disk, said rolling keels being so positioned that in a laterally outwardly tilted position the respective rolling keel is above water and only the corresponding long wing section dips into the water so that the respective wing end disk functions as a lift producing wing surface.
