Definitions

  • the invention relates to a sailing yacht according to the preamble of claim 1.
  • Sailing yachts especially high-performance sailing yachts, are cheaply designed with regard to the use of wind forces, minimization of water resistance and controllability and stabilization. It is desirable that the relevant properties of known sailing yachts are further improved.
  • FR-OS 24 45 795 also shows a sailboat configuration, with laterally arranged elements being pivotable about axes parallel to the ship's axis and above the waterline.
  • ballast swords of which the windward one is swung out of the water. With this shifting of the ballast its effectiveness is increased and at the same time the water resistance of the keel to be swung up is switched off.
  • the invention has for its object to provide a generic sailing yacht in such a way that it has significant improvements over previous solutions with regard to the utilization of wind forces, minimization of water resistance and in terms of controllability and stabilization.
  • the figure shows a perspective view of a sailing yacht 1 with features according to the invention in a wind-upwind configuration, essentially consisting of a ship's hull 2, a sail 3, which is held by a profile mast 4 in a manner known per se, with a canard rudder 8 below the bow 5 is arranged, at the lower end of which there is a bow wing 9.
  • the spinnaker usual for sailing in front of the wind and additional special sails for space wind and half wind courses are not shown here.
  • the rear keels 10, 10 ' are pivotally mounted about axes of rotation running approximately parallel to the ship's axis.
  • Each rear keel 10, 10 ' can be pivoted from an approximately vertical to an approximately horizontal position and vice versa.
  • each side wing 11,11' is arranged in the manner of an end plate.
  • Each side wing 11,11 ' consists of a partial wing 14,14' arranged on the inside of the bilge keel 10,10 'and a partial wing 13,13' arranged on the outside thereof.
  • the inner partial wing 14, 14 ' has an end disk wing 15, 15' at its tip.
  • the side wings 11,11 'together with the front wing 9 form a controllable Three-point wing system, in particular the bow wing 9 is used for tamping and longitudinal trim control.
  • the bilge keels 10, 10 ' provide controllable hydrodynamic lift for lateral keel operation. As a result of this wing effect, the friction and wave resistance of the sailing yacht are reduced in a known manner.
  • the windward keel is folded up. In this position, the entire bilge keel 10 is above the water surface, but the long partial wing 14 is partially immersed in the water, so that the end disk wing 15 now acts as a hydrodynamic support and control element.
  • the end plate wings 15, 15 ' are in operative connection with a position control, not shown here, of a known type, so that heel control is achieved by means of the controllable end plate wings 15, 15'. It is particularly advantageous here that the hydrodynamic resistance of the yacht is reduced by folding up the bilge keel 10. Even when the windward keel is folded up, the three-point wing system remains, although the side wing 11 of the windward keel is replaced by the relevant end disk wing 15.
  • the Kimmkiele 10,10 'can have a known variable curvature for generating lateral lift.
  • the variable arch elements can be controlled by a control system.
  • ballast containers 17, 17' At the ends of the bilge keels 10, 10 'there are two ballast containers 17, 17'. These can hold a suitable liquid serving as ballast, such as mercury, which can be moved by a pump between the two ballast containers 17, 17 '. It is also conceivable that an additional movable trim ballast in solid or liquid form is used, also coupled with the position control and control system.
  • sliding flaps 16, 16 ' At the side of the rear 7 there are two sliding flaps 16, 16 ', which can be folded up in leeward travel and which contribute to controlled longitudinal trim (pitching torque control) and hydrodynamic lift generation when the vehicle is largely sliding.
