Definitions

  • the invention relates to a watercraft according to the preamble of the first claim.
  • Watercraft in particular boats and yachts, are generally manufactured in a process in which the lower part, called the boat hull, consists of a hydrodynamically shaped part and is dimensioned with a corresponding wall height and wall thickness in order to withstand heavy seas or ground contact, if necessary to let as little water as possible come over the deck.
  • the boat hull consists of a hydrodynamically shaped part and is dimensioned with a corresponding wall height and wall thickness in order to withstand heavy seas or ground contact, if necessary to let as little water as possible come over the deck.
  • the upper part of the boat is the end of the hollow
  • the drive motor which is mounted directly on the boat hull reinforcements, possibly dampened by rubber bearings.
  • the propeller system with a shaft bracket, sterndrive, Jet propulsion or outboard engine, the rudder, engine cooling elements and gas outlet pipes.
  • the boat hull and the deck are mostly pushed together at the level of the rubbing strake, riveted or screwed, and the parts to be joined are elegantly concealed by the rubbing strake.
  • the corresponding hull length is required, which automatically determines the space on the deck and vice versa, a required space on deck automatically leads to a certain hull length.
  • the invention has for its object to avoid the disadvantages of the prior art in a watercraft of the type mentioned and to provide a watercraft whose design and hull length is independent of the space on deck.
  • the watercraft has at least two stacked floating bodies, the lower floating body having a buoyancy-generating hydrodynamic function and being the carrier of the upper floating body and the upper floating body having a hydrodynamic function which essentially repels the water laterally. Due to the functional separation of the hull into two independent hydrodynamically complementary floating bodies, a watercraft can be produced more efficiently and therefore more cost-effectively because the lower floating body as a functional and floating body can be manufactured separately and in a location-independent manner and pre-tested, while the upper floating body as a working, Living space, storage space and helmstand, similar to a motorhome or camping car, can be oriented according to aesthetic and movement-compliant aspects and can also be produced regardless of location.
  • the lower floating body serves as an independent floating body to carry the main hydrodynamic buoyancy task and load, in particular with the engine, drive, control elements, connecting means with the second fuselage part and coupling means for roadworthy operation.
  • the upper part of the fuselage also serves as a separate floating body with secondary hydrodynamic functions, such as the lateral water flow, and in particular to provide a space suitable for living and working for the watercraft crew.
  • This upper part of the fuselage advantageously has mating coupling means for operation suitable for driving and can be saddled and connected to the floating body positioned underneath by means of fastening elements.
  • the hydrodynamic lower hull part may be made of a different material than the less stressed one - in terms of engine and drive attachment, ground contact, etc.
  • Upper part of the fuselage which can be made from a cheaper and / or thin-walled material.
  • Both bodies advantageously have a flexible coupling means which can easily connect the power supply, the electrical signals, the steering and engine power reversing means to one another.
  • Another advantage is that the length of the lower float can be equal to the total length of the watercraft.
  • Today's watercraft have a waterline of only about 85% of the total length of the vehicle, because modern bow design is no longer almost at right angles to the water surface.
  • the invention makes it possible to use a lower hydrodynamic floating body, which corresponds to the overall length of the watercraft, because the lower floating body has a large part of a height which corresponds approximately to the waterline of the watercraft when it is lying down and as a result does not visually detract from the modern bow design , This also increases the stability of the watercraft in rough seas.
  • the lower float has a casing in the area of the engine, called the device collar, so that in principle there is no water ingress into the engine, fuel and auxiliary unit room.
  • Float has a corresponding recess in the area of the device collar with a hatch, so that the inspection and maintenance of the unit and accessories is also easy to do.
  • the consequent separation of the two hydrodynamic floats leads to a low center of gravity due to the concentrated machine and accessory mass and the corresponding solid use of materials on the lower float area.
  • the upper float area can therefore be made correspondingly lighter and the watercraft thus achieves an overall better stability.
  • Figure 1 is a side view of a watercraft with a lower float assembled with an upper float.
  • FIG. 2 shows a side view of a watercraft with the lower floating body with a schematically illustrated sterndrive with an integrated rudder;
  • FIG. 3 shows a side view of a watercraft with the lower floating body with the variant of an outboard with its integrated rudder;
  • FIG. 4 shows a side view of a watercraft with the lower floating body with the variant of a shaft drive and separate rudder
  • Fig. 5 is a side view of a watercraft with the lower float with the variant of a jet drive.
  • 1 and 2 is a watercraft, comprising a lower floating body 1, which also serves as the main buoyancy body, joined with an upper floating body 2, a deck 3, a steering position 15, a schematic sterndrive 5 with integrated rudder 13, transverse thruster 12 ⁇ Trim and stabilization flaps 14 shown.
  • the lower floating body 1 can advantageously be optimized hydrodynamically to a specific load and travel speed map, e.g. in that all data relating to buoyancy, resistance, stability, load and other relevant parameters are recorded in a test tank and the hydrodynamic part is adapted in accordance with the setpoint specifications, so that the lower float 1 can then also be driven under real conditions.
  • the upper floating body 2 is placed over the lower floating body 1 and can have corresponding recesses in the floor area in order to leave space for a device collar 10, as well as further parts which have to fit together for aesthetic or technical reasons.
  • the two floating bodies 1 and 2 can lie on top of one another or can be nested within one another.
  • the lower floating body preferably has an overall height - without equipment collar 10 - which corresponds approximately to the level of the water line when loaded and when the watercraft is at a standstill.
  • the upper float 2 which u.a. includes the work, living, storage space and helm station, together with the deck 3 also takes over the protective task against wind and high waves.
  • the hydrodynamic part of the upper float is mostly limited to the lateral water way when diving into the waves.
  • the lower floating body 1 essentially comprises the sterndrive 5 with integrated rudder 13, the device collar 10, a location for the motor 17 and a drive suspension device 16, coupling means 11, fastening points 9 for the assembly of the two floating bodies 1 and 2 with each other, the transverse thruster 12 and the trim and stabilizing flaps 14.
  • the drive motor 17 is not directly visible, because this, together with the fuel tank, which can also be arranged in the upper float, additional units, etc., is protected with a suitable means becomes.
  • This measure also means that there is no need for boreholes in the Water part of the lower float 1 for the various hydraulic lines, such as for trim and stabilizing flaps 14, transverse thrusters 12, rudder systems 13, Z - drive lifting devices, but also cable guides for echo sounder, electrical stabilizers or engine cooling lines, all of which are on the outer lower float wall and the device collar 10 are pulled up and in the upper part - that is to say in the above-water area - the lines can then be fed along their destination on the inner wall of the upper floating body 2. This improves safety with regard to leaks and the lines are practically no longer visible as soon as the upper floating body 2 is placed over them.
  • a flexible coupling 11 connects all the technical means that belong to the readiness to drive a watercraft and which mostly lead to the steering position 15, such as electrical lines to indicate the engine instruments, control lines for the trim and stabilizing flaps 14, transverse thrusters 12, and also separately electricity for the galley, lighting the cabins, exterior markings of the watercraft etc., as well as the mechanical connections such as gear changeover, engine power and rudder function control.
  • the control station 15 advantageously includes the steering, the power lever, the transmission, the displays and the actuators for the technical means such as the trim and stabilization flaps 14, the propeller adjustment and the thruster 12.
  • the control commands and the other functions mentioned above can also be wireless at best , e.g. be transmitted by radio between the two floating bodies.
  • attachment points 9 are shown, which connect the lower floating body 1 to the upper floating body 2, wherein the connection can be rigid or elastic.
  • FIG. 3, 4 and 5 show how it is possible to respond to different market needs with a given upper float, should the market, for example request more in the short term for other types of drive or any configuration of the lower float.
  • the new situations can be entered quickly and the upper hull, ie the effective vehicle layout, division and equipment, can be left as it is.
  • the sterndrive can simply be replaced by an outboard 6.
  • Individual preferences such as shaft systems 7, see FIG. 4, or jet drive 8, see FIG. 5, can also be easily satisfied.
  • the drive suspension device 16 is adapted accordingly for these different drive variants, so that the corresponding drive can be fastened.
