Problems solved by technology

At the same time, always less water passes under the bottom of the boat in the direction of the stern, which especially reduces the efficiency of the drive propeller located centrally in the rear
In addition, strong transverse waves formed behind the ship and hindered the ship to some extent
[0006] For water that can be used to propel the boat, in principle the optimum propulsion condition exists on the bow side, but this optimum condition cannot be adopted with conventional bow shapes

Embodiment Construction

[0039] Figures 1 to 4 An embodiment of the vessel of the invention in the form of a riverboat 10 is shown. In the various figures, the same parts are given the same reference numerals.

[0040] The bow region 18 of the riverboat 10 according to the invention is shown in the respective figures. Any useful device 14 may be disposed on the top surface 50 of the hull 12 . The wedge-shaped guiding elements 24 of the present invention are provided on the bottom surface 22 of the hull 12 facing the water on the port and starboard sides. According to the invention, the guide element 24 tapers forwards into a bow-side wedge shape 26 ; Thus, the shape of the guide element 24 can be seen as a vertical wedge.

[0041] Depend on image 3 As can be seen in the horizontal cross-sectional view of the wedge-shaped guide element 24, the inner side of the wedge-shaped guide element 24 delimits a partial region 28 with a substantially rectangular cross-section. According to the present inv...

Abstract

The invention relates to a watercraft, particularly a river boat, with a hull for receiving useful devices and with propulsion units for generating a driving force and which are located on the hull. The watercraft according to the invention is characterized in that guiding elements are provided in the bow area on the underside of the hull, which have a vertical, forwardly tapering wedge shape, that the propulsion units in the bow area are set back from the wedge-shaped guiding elements, that between the guiding elements is provided a partial area of the hull constructed in the form of a horizontal wedge and that the propulsion units are pivotably mounted.

Description

technical field [0001] The present invention relates to a ship, in particular to a river ship. Background technique [0002] Such a ship is known, for example, from DE 3712534 A1, which has a hull for accommodating useful devices and a propulsion unit located on the hull for generating the driving force. Guide elements are also provided in the bow region on the underside of the hull, each guide element having a vertical, forwardly tapering wedge shape. Finally, horizontal wedge-shaped hull partial regions are provided between the guide elements. [0003] For riverboats, the flow of water around the hull is problematic as speed and width increase in shallow and laterally limited channels. [0004] A conventional bow primarily moves the water laterally outward, with much less water (to little to no water) passing under the bottom of the boat. [0005] The boat is said to be drawn towards the bottom of the channel and the lateral velocity increases. Then, the water always f...
