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.
  • a yacht consisting essentially of a ship's hull and a sail, with a bow and stern keel, the lower ends of which are each provided with a lift control wing, at the side on A hull is arranged on each hull arm, the end of which has a downwardly projecting wing handle which carries a plurality of lift control wings, the lift control wings forming a four-point wing system for generating lift as well as for control and stabilization.
  • the ship is shown in high speed with the hull and outrigger arms above the waterline. This yacht shows no means of accelerating the transition phase from the immersed to the high-speed state.
  • the invention has for its object to provide a generic sailing yacht in such a way that it has significant improvements in terms of utilization of wind forces, minimization of the induced water resistance and reduction of the wetted area and in terms of stabilization.
  • FIG. 1 shows in perspective a sailing yacht 1 in the upwind sailing configuration, consisting essentially of a ship's hull 2, a sail 3, which is designed as a full profile sail and a tandem keel system consisting of a bow keel 13 and a stern keel 14 and a four-point Wing system, consisting of two lateral lift control wings 8,8 'and two lift control surfaces, which are arranged on the keels 13,14.
  • 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.
  • boom arms 6,6 ' are arranged, at the ends of which there are wing handles for receiving the lateral lift control wings 8,8'.
  • a floating body 12, 12' of hydrodynamic shape is arranged at the ends of the cantilever arms 6, 6 '.
  • a floating body 12, 12' of hydrodynamic shape is arranged.
  • To the Keels 13, 14 each have a bow lift control surface 9 and a rear lift control surface 10.
  • the jib arms 6, 6 ′ are narrow-surface and swept forward like wings.
  • the bow area 5 of the fuselage 2 has a slim shape.
  • the underwater ship in question has a concavely curved V-shape in cross section. This water-repellent shape deflects splash water to the sides.
  • the sail 3 is arranged approximately midships, where there are approximately the roots of the cantilever arms 6,6 '.
  • the cockpit 4 is located aft of the sail 3 and is of a broad shape, so that there is good visibility even to the front.
  • a rear control carrier 7 connects to the cockpit 4, the end of which supports the keel 14. This carrier 7 is of minimal cross-section for reasons of weight and aerodynamics.
  • the sail 3 has a geometric twist that can be adapted to the regional wind conditions. Furthermore, the sail 3 shows an end plate 17 for reducing the induced resistance.
  • the floating bodies 12, 12 ' are hydrodynamically shaped so that they have a minimal water resistance when traveling with immersed floating bodies 12, 12'. These bodies are still used as ballast tanks.
  • a ram-powered intake system is provided, which means that the tanks can be filled quickly if necessary.
  • To empty the tanks they are each provided with at least one quick release flap on their underside or at the rear.
  • appropriate entry openings are provided at suitable stowage points, preferably in the area where the bow and stern control surfaces intersect.
  • extendable receiving devices can also be arranged at other points on the hull, for example directly at the floating bodies 12, 12 '.
  • the yacht lies in the water with the floating bodies 12, 12 'and the keels 13, 14.
  • the four wings take effect so that the hulls lift off the surface of the water.
  • This transition phase is accelerated by the hydrodynamic shape of the hull and the floating bodies 12, 12 'designed for maximum lift generation.
  • all known hydrodynamic means such as step-shaped or S-shaped underwater contours and the like, can be used.
  • the picture shows the yacht at high speed on the wind. The entire hull is located above the waterline. There are only the keels 13, 14 and the port-side lateral control wing 11 ' immersed. The ship is thus carried by the bow and stern lift control surfaces 9 and 10 and the leeward lift control wing 8 '.
  • the air wing 8 is immersed. In this sailing condition, the yacht has a minimal wet area, which considerably reduces water resistance. In the case of ramming movements, a damping effect results from the fact that the bow keel 13 and the stern keel 14, in particular in their upper regions, are designed in such a way that their cross-sectional area decreases steadily downwards. This shape causes the keel displacement to increase rapidly with deeper immersion, so that the keels act as hydrostatic stabilizers.
  • the axes of the lateral lift control wings 8,8 ' form a V-shape in the front view. This ensures that the vertically projected area of the respectively immersed leeward buoyancy control wing increases when the yacht leans more strongly under the wind load. This results in a stabilizing effect around the longitudinal axis.
  • the yacht has numerous means for quick maneuvering.
  • the keels 13, 14 are designed to be pivotable about their profile axes. This results in a very effective control around the vertical axis.
  • the lateral control wings 11, 11 'and the lift control wings 8, 8' are each designed to be pivotable about their profile axis.
  • the invention is not limited to the configuration of the yacht shown and to the exemplary embodiments described. Rather, it extends to all configurations that are conceivable within the scope of the claims.
