Marine Vessel

Abstract

A marine vessels comprising at least one foil extending downwards from the keel under the body of the vessel. The marine vessel comprises a foil being fully submerged in the water and the angle of attack of which can easily be changed by a low drive force and which can bear the propellers.

1 . A floating marine vessel ( 1 ), comprising:
 a body ( 2 ) having a front end and a rear end being distant from the front end,   a motor for moving the marine vessel, a keel ( 3 ) extending along the bottom of the body ( 2 ) from the front end to the rear end thereof, at least one shaft ( 6 ) extending downwardly from the body ( 2 ), the shaft being connected to the motor from one end and to at least one propeller ( 7 ) from other end, at least one foil ( 4 ) extending transversally to the longitudinal direction of the body ( 2 ) and under the body ( 2 ) of the vessel,   at least one hinging mechanism ( 10 ) for at least partially pivoting the foil ( 4 ) around an axis ( 9 ) transversal to the body ( 2 ), and   at least one bearing mechanism ( 12 ) for bearing the at least one shaft ( 6 ) by the foil ( 4 ).   
     
     
         2 . The marine vessel ( 1 ) according to  claim 1 , further comprising at least one drive mechanism ( 11 ) connected to the foil ( 4 ) at a point distant from the hinging mechanism ( 10 ) for pivoting the foil ( 4 ) around the axis ( 9 ). 
     
     
         3 . The marine vessel ( 1 ) according to  claim 1 , wherein the hinging mechanism ( 10 ) comprises a foil shaft cavity ( 10 . 1 ) formed in a transversal direction to the foil ( 4 ) and a foil shaft ( 10 . 2 ) disposed in the cavity. 
     
     
         4 . The marine vessel ( 1 ) according to  claim 1 , wherein the at least one shaft ( 6 ) comprises propeller shafts ( 7 . 1 ) connected by means of a universal hinge ( 8 ) to one of shaft ends being distant from the motor, and the propeller shafts ( 7 . 1 ) being borne on the foil ( 4 ). 
     
     
         5 . The marine vessel ( 1 ) according to  claim 1 , wherein the bearing means ( 12 ) comprises a bearing housing ( 12 . 1 ) formed on the foil ( 4 ), a sleeve ( 12 . 3 ) disposed in the housing ( 12 . 1 ), and a bearing element ( 12 . 2 ) disposed in the sleeve ( 12 . 3 ). 
     
     
         6 . The marine vessel ( 1 ) according to  claim 2 , wherein the drive element ( 11 ) comprises a drive element handle ( 11 . 1 ) extending vertically downwardly from the body ( 2 ). 
     
     
         7 . The marine vessel ( 1 ) according to  claim 6 , wherein the drive element handle ( 11 . 1 ) comprises a connection element ( 13 ) providing one end of the drive element handle being distant from the drive element to be fixed to the foil ( 4 ).
