Definitions

  • the present invention relates to a watercraft with static and dynamic buoyancy, which has high maneuverability at high speed, with a hull, with at least one keel and with at least one drive.
  • watercraft have a wide variety of hull shapes.
  • the operational readiness is also largely retained in the event of a drive system failure, whereby the two-screw drive also enables better maneuvering properties.
  • DE C 36 39 175 describes a ship's hull for small vehicles and high speeds, the ship's hull below the floating water line consisting of a bulge-shaped displacement body that extends almost over the entire length of the ship, which is slender in the bow, and then aft over about two thirds the length of the ship thickens evenly, then narrows again towards a large central propeller and onto which a ship shape with a V-shaped frame character shoots, which in its rear area merges into a tunnel that covers the bead body and the propeller, so that there is a strongly concave trough-shaped shape above the bead.
  • the hull comprises on the one hand a curved lower wall and on the other hand a substantially flat upper wall or ceiling.
  • the lower curved wall of the ship's hull can have the shape of a spherical cap or a central part in the form of a spherical cap and have a protruding edge on its periphery, the generatrix of which has a smaller radius of curvature than the spherical cap.
  • This watercraft primarily serves to surf on the water with a sail attached to a standing mast, which is arranged along the axis of rotation of the ship's hull.
  • a vertical shaft is provided, in which the vertical transmission shaft of an outboard motor is inserted with a propeller.
  • From EP-Al-0242408 is a sailboat with a predominantly closed boat hull, at least one mast tree supported in the boat hull and one
  • This sailboat is said to have a high level of seaworthiness and a hull with high strength, high positional stability and independent erectability after capsizing.
  • the shape of the boat hull is determined by cross sections on the Form pointed triangles, in particular equilateral triangles with convexly curved sides and shrink continuously or approximately to the size of the points in the direction of the bow and stern, so that the three corners of the three corners meet and a body largely symmetrical about its main axes , in particular an ellipsoid.
  • the outline of the boat hull can correspond approximately to an ellipse in side view or plan view.
  • the object of the present invention is to provide a watercraft with static and dynamic buoyancy, which has high maneuverability at high speed, which improved
  • a watercraft with static and dynamic buoyancy which has high maneuverability at high speed;
  • the watercraft has a hull with a lower and an upper half, furthermore at least one keel and at least one drive, the hull being essentially elliptical in longitudinal section and in plan view.
  • the fuselage is also essentially elliptical in cross section through the center point of the longitudinal axis, the axes of all ellipses being unequal are.
  • the lower and the upper half of the fuselage are preferably symmetrical.
  • the advantage of reduced hull resistance is achieved by generating small entry angles in the submerged bow , as well as the generation of a post-flow field which is uniform in the axial, radial and tangential direction while at the same time reducing an oblique flow.
  • This improvement in the flow properties of the ship's hull also has the advantage of reduced cavitation and the resulting noise and vibrations.
  • the watercraft is particularly agile even at high speeds with a reduced risk of capsizing.
  • Figure 2 shows an axial section along the longitudinal axis
  • FIG. 3 is a plan view. In the figures, the same parts are provided with the same reference symbols.
  • the watercraft designed according to the invention with static and dynamic buoyancy is provided with a hull 1, which is provided on its underside with at least one keel 4, and with at least one drive 5.
  • a control or command station 3 is provided on its top for receiving an or several observers, this control position 3 for example when hunting large fish also with a weapon 6, such as. B. a harpoon can be provided.
  • the fuselage has an essentially ellipsoidal shape.
  • the fuselage also has an essentially ellipsoidal shape in axial section along the longitudinal axis 2.
  • FIG. 3 shows a plan view of the watercraft according to the invention, it being clear from this figure that the shape of the hull 1 is also essentially ellipsoidal in plan view.
  • Such a watercraft is simple and inexpensive to manufacture; it is particularly characterized by high maneuverability at high speed, making it suitable for a wide range of applications.
