Sailing Vessel

Abstract

There is disclosed a sailing vessel comprising a buoyancy body at which a rotatable keel is held which can be adjusted by setting a rudder.

1 . A sailing vessel comprising a hull or buoyancy body which supports a sailing rig and at which a keel is pivot-mounted, the keel being operatively connected to a rudder for adjusting a change of sailing direction, wherein the operative connection is such that a rotation of the keel can be initiated via the rudder substantially only when a predetermined critical rudder angle is exceeded or a torque acts upon the keel. 
     
     
         2 . The sailing vessel according to  claim 1 , wherein a center of lateral resistance of the keel is offset vis-à-vis a center of pressure of the sailing rig. 
     
     
         3 . The sailing vessel according to  claim 1 , comprising a holding means substantially maintaining the position of the keel relative to the buoyancy body up to the critical rudder angle and releasing the keel when the critical rudder angle is exceeded so that a relative movement between the keel and the buoyancy body takes place based on the rudder angle. 
     
     
         4 . The sailing vessel according to  claim 3 , wherein the holding means connects the keel by force-fit and/or form-fit to the buoyancy body. 
     
     
         5 . The sailing vessel according to  claim 1  wherein the rudder has a rudder shaft which is rotatable with the keel about a pivot axis of the keel. 
     
     
         6 . The sailing vessel according to  claim 1 , wherein the rudder and the keel are designed as a constructional unit or as separate components. 
     
     
         7 . The sailing vessel according to  claim 1 , wherein the buoyancy body has a rotation-symmetric or elliptic design viewed in the pivot axis of the keel. 
     
     
         8 . The sailing vessel according to  claim 1 , wherein the keel is a long keel. 
     
     
         9 . The sailing vessel according to  claim 1 , wherein the critical rudder angle is approximately 15°. 
     
     
         10 . The sailing vessel according to  claim 1 , comprising an indicator for indicating the keel position with respect to the buoyancy body. 
     
     
         11 . The sailing vessel according to  claim 1 , wherein the sailing rig includes a wing sail. 
     
     
         12 . The sailing vessel according to  claim 1 , wherein the sailing rig is designed to be swiveling. 
     
     
         13 . The sailing vessel according to  claim 1 , comprising a ballast element which is movably supported, with respect to the sail, at or on the buoyancy body. 
     
     
         14 . The sailing vessel according to  claim 1 , wherein the sail is supported such that it is arranged ahead of the keel at least seen on a downwind course. 
     
     
         15 . A sailing vessel according to  claim 1 , wherein the sail is guided on the buoyancy body in an adjustable or displaceable manner.
