Maneuvering system for watercraft

Abstract

The invention relates to two maneuvering systems, each of which is located in a housing and which are placed as far apart from each other as possible on the stern in order to this enable a watercraft to be moved precisely on the longitudinal axis, laterally, forward/backward and on the vertical axis. By means of a modified throttle and gear lever of the main engines, referred to as a manipulator, which is coupled with the functions of the maneuvering systems and, with the integration of the steering wheel, all of the maneuvering functions and driving modes can be carried out and automated or act in a supportive capacity by means of the controller, or the manual incorporation of the main engines can be permitted at any time by means of an actuator.

 the maneuvering system is supported in a housing or in a tunnel housing, 
 the maneuvering system can be manipulated by a user and controlled by the controller, and 
 the main engine and the maneuvering system can each generate a separate thrust.

         5 . The watercraft according to  claim 1 , wherein the maneuvering system includes one of a hydraulic pump and control valve or a control flap and thrust reversal flap. 
     
     
         6 . The watercraft according to  claim 1 , wherein:
 the maneuvering system includes a motor,   upon full acceleration of the watercraft in a predefined speed window of the motor or speed window of the hull, the maneuvering system and the main engine operate together; and   below a predefined speed of the motor or speed of the hull, only the maneuvering system operates.   
     
     
         7 . The watercraft according to  claim 1 , wherein:
 the maneuvering system includes a plurality of maneuvering systems and the main engine includes a plurality of main engines,   a lever regulates engine speed and reversal for several main engines of the plurality of main engines and several maneuvering systems of the plurality of maneuvering systems by means of a longitudinal movement in a direction of the longitudinal axis of the hull, and   with a transverse movement of the lever, a main direction and speed of parallel sideways travel is controlled, and fine controlling is performed using a steering wheel or automatically using a gyro sensor.   
     
     
         8 . The watercraft according to  claim 1 , wherein the housing or the tunnel housing is attached to the stern of the hull and has a stepped bottom. 
     
     
         9 . The watercraft according to  claim 1 , wherein the housing can be tilted or folded up using operating cylinders, a pivot bearing and a trim button. 
     
     
         10 . The watercraft according to  claim 1 , wherein the maneuvering system includes two maneuvering systems that are respectively mounted on the stern of the hull and, between the two maneuvering systems, one or two propellers are active and the two maneuvering systems provide a jet or propeller drive. 
     
     
         11 . The watercraft according to  claim 1 , wherein the housing or the tunnel housing generates a static and/or dynamic buoyancy. 
     
     
         12 . The watercraft according to  claim 1 , wherein:
 the maneuvering system includes a motor, a shaft and an impeller or maneuvering propeller that are rigidly or elastically supported on a bottom of the housing or the tunnel housing, and   the maneuvering system generates thrust using a nozzle or control flap and a thrust reversal flap.   
     
     
         13 . The watercraft according to  claim 1 , wherein:
 the maneuvering system includes a flap, and   at a starting speed of the hull, the flap closes an inlet or a water flow at the inlet is diverted by the flap.   
     
     
         14 . The watercraft according to  claim 1 , wherein:
 the maneuvering system includes a maneuvering propeller, and   at a starting speed of the hull, the maneuvering propeller is raised.
