The problem with a sailing yacht is known. High superstructure, mast, sail, the wind pressure and thus the drift. In order to prevent the drift and capsizing of the boat, a heavily ballasted keel is attached to the hull according to the age-old and fully superseded custom. This obsolete type of construction makes the boat sluggish and inflexible. Four extendable and retractable steering fins replace keel and rudder much more effectively. They guide the hull as if on rails and make it manoeuvrable like a formula-one racing car. Additional ballast trimming vanes at the steering fins enable the entire ballast weight to be trimmed over the entire width of the vessel, and at the same time forward and aft. It is thus possible to sail the sailing yacht far closer to the wind. The electronically, hydraulically controlled ballast trimming vanes stabilise the boat in the longitudinal axis, keep contact with the water and put the boat into an optimum planing phase.
