Vessel with a Hull

Abstract

The invention relates to a watercraft ( 1 ) having a hull ( 2 ) and at least one arm ( 3 ) protruding from the hull ( 2 ), on which at least two hydrofoils ( 4, 5 ) are mounted so they are each pivotable about a first pivot axis ( 6 ), preferably about a shared pivot axis. To improve the maneuverability and stability of the watercraft, the at least two hydrofoils ( 4, 5 ) are pivotable independently of one another.

1 . A watercraft having a hull and at least one arm protruding from the hull, on which at least two hydrofoils are each mounted so they are pivotable about a first pivot axis, preferably about a shared pivot axis, wherein at least two hydrofoils are pivotable independently of one another. 
     
     
         2 . The watercraft according to  claim 1 , wherein at least two hydrofoils, which are pivotable independently of one another, are arranged at the same height on opposing sides of the arm. 
     
     
         3 . The watercraft according to  claim 1 , wherein the hydrofoils are arranged in the end region of the arm, which faces away from the hull. 
     
     
         4 . The watercraft according to  claim 3 , wherein the first pivot axis of the hydrofoils is transverse, preferably perpendicular, to the longitudinal axis of the hydrofoil and/or to the travel direction of the watercraft. 
     
     
         5 . The watercraft according to  claim 4 , wherein the hydrofoils are each pivotable by at least 60°, preferably by at least 90° about the first pivot axis. 
     
     
         6 . The watercraft according to  claim 5 , wherein the arm is mounted so it is pivotable on the hull, wherein the arm is preferably pivotable hi relation to the hull by at least 60°, preferably by at least 90°. 
     
     
         7 . The watercraft according to  claim 6 , characterized in that the pivot axis of the arm is transverse to the travel direction of the watercraft and/or essentially parallel to the first pivot axis of the hydrofoils. 
     
     
         8 . The watercraft according to  claim 7 , wherein drives, which are actuable independently of one another, preferably cylinder drives, are integrated into the at least one arm, wherein one of the drives interacts with one of the hydrofoils and another drive interacts with another hydrofoil. 
     
     
         9 . The watercraft according to  claim 8 , wherein a hydrofoil bearing is integrated into the arm and the drives are housed in the region of the hydrofoil bearing. 
     
     
         10 . The watercraft according to  claim 9 , wherein the drives are cylinder drives, the piston rods of which are essentially parallel to one another and point in opposite directions. 
     
     
         11 . The watercraft according to  claim 10 , wherein the drives are opposite to one another and/or are arranged on opposing sides of the hydrofoil bearing. 
     
     
         12 . The watercraft according to  claim 11 , wherein the piston rods of the cylinder drives are each eccentrically linked on a rotational attachment, which is mounted in the hydrofoil bearing and is connected to the respective hydrofoil. 
     
     
         13 . The watercraft according to  claim 12 , wherein the piston rod of one cylinder drive is connected through a recess, which is preferably in the form of a partial ring, of a rotational attachment to the other rotational attachment. 
     
     
         14 . The watercraft according to  claim 13 , wherein the hydrofoils are pivotable about a second pivot axis in addition to the first pivot axis in relation to the arm, wherein preferably the second pivot axis extends essentially in parallel to the longitudinal axis of the hydrofoil and/or essentially horizontally. 
     
     
         15 . The watercraft according to  claim 14 , wherein the watercraft has at least two arms, the linkage points of which on the hull are spaced apart from one another in the travel direction, and/or the watercraft has at least two arms, the linkage points of which on the hull are spaced apart from one another transversely to the travel direction. 
     
     
         16 . The watercraft according to  claim 15 , wherein a third pivot axis is provided, which is preferably perpendicular to the first pivot axis.
