Definitions
- the present invention relates to a watercraft static and dynamic buoyancy, which is high Exhibits agility at high speed with a Hull, with at least one keel and with at least one Drive.
- Watercraft have the depending on their purpose different hull shapes. Fast, small ships, especially motor boats as well Defense ships, primarily as Multiple screwdrivers built, as with a two or four screwdriver arrangement the tendency of the propellers to cavitate reduced and a hydrodynamic irregularity of the Drive should be avoided. With two screwdrivers remains operational readiness also in the event of a failure Drive system largely preserved, with the addition Two-screw drive better maneuverability allows.
- Another watercraft that is self-contained Pick up drive means and at least one passenger can carry the water, with the hull made of a rotating floating lens that gives it Gives the shape of a saucer is from DE A 31 20 752 known.
- the hull comprises one arched bottom wall and on the other hand essentially one flat top wall or ceiling. So the lower arched Wall of the hull shaped like a spherical cap have or a middle part in the form of a Spherical cap and a towering on its periphery Border, the generatrix of which is smaller Radius of curvature than the spherical cap has.
- This Watercraft is primarily used with one on a fixed mast attached to the sail along the The axis of rotation of the hull is arranged on the water to surf. At one in this pre-release
- the embodiment described is a vertical one Shaft provided in which the perpendicular transmission shaft an outboard motor used with a propeller is.
- From EP-A1-0242408 is a sailing boat with a predominantly closed hull, at least one in Boat hull supported mast and one Rudder device known.
- This sailboat is said to be one high seaworthiness and a hull with high strength, high positional stability and independent erectability capsize.
- the shape of the Boat hull determined by cross sections on the Pointed, especially equilateral triangles with form convex curved sides and each in Direction to the bow and stern continuously or roughly reduce to the point size so that the three of the Hit corners of the three corner edges and one around its main axes are largely symmetrical bodies, in particular an ellipsoid arises.
- the outline of the Boat hull can be viewed in side or top view roughly correspond to an ellipse.
- the object of the present invention is a Watercraft with static and dynamic buoyancy too create a high maneuverability with great Has speed that improved Has flow properties due to a reduced Hull resistance and that is inexpensive to manufacture.
- a watercraft with static and dynamic buoyancy which is highly maneuverable at high speed;
- the watercraft has a hull with a lower and an upper half on, furthermore at least one keel and at least one Propulsion, the fuselage in longitudinal section and in the Top view is substantially elliptical.
- the hull is in cross section through the Center of the longitudinal axis essentially also elliptical, the axes of all ellipses unequal are.
- the lower and the upper half of the Fuselage symmetrical.
- the new hull shape for a watercraft the for example as a motorboat for regatta use, as fast reconnaissance boat in case of defense or also as a surveillance vehicle on busy sea roads Avoiding environmental pollution can be used the advantage of a reduced trunk resistance through the Generation of small entry angles in the submerged bow achieved, as well as the generation of an axial, radial and tangential direction of the uniform wake field while reducing an inclined flow.
- Avoiding environmental pollution can be used the advantage of a reduced trunk resistance through the Generation of small entry angles in the submerged bow achieved, as well as the generation of an axial, radial and tangential direction of the uniform wake field while reducing an inclined flow.
- By improving the flow properties of the Ship hull will also have the advantage of a reduced cavitation and the resulting Noise and vibrations achieved.
- the watercraft is particularly agile even at high speeds at the same time reduced risk of capsizing.
- the designed according to the invention Watercraft with static and dynamic buoyancy provided with a fuselage 1, the bottom with at least one keel 4 is provided, as well as at least a drive 5. On its top is a control or Command stand 3 is intended to accommodate one or more Observer, this control position 3 for example hunting large fish with a weapon 6, such as. B. a harpoon.
- the fuselage has an axial section along the longitudinal axis 2 also substantially Ellipsoid shape.
- Figure 3 shows a plan view of the invention Watercraft, it being apparent from this figure that the shape of the fuselage 1 in the top view is substantially ellipsoidal.
- Such a watercraft is simple and inexpensive produced; it is particularly characterized by a high Maneuverability at high speed, making it for a variety of uses is suitable.
