Finkeel for boats with foldable leeboards

Abstract

The invention relates to a finkeel ( 2 ) for boats, having of a fixed part ( 3 ) attached to the hull ( 1 ) and a movable part comprising two leeboards ( 4, 5 ) that can be orientated in an independent manner. According to the invention, each leeboard ( 4, 5 ) consists of at least one upper element ( 4 a , 5 a ) hinged to the fixed part ( 3 ) of the finkeel and a lower element ( 4 b , 5 b ) hinged to the upper element, so that the leeboards can be folded up towards the fixed part ( 3 ) of the finkeel, to achieve lateral overall dimensions smaller than the width of the hull.

1 . Finkeel for boats, having a fixed part to be attached to the hull, a movable part comprising two leeboards hinged to the fixed part and rotatable independently of each other with respect thereto, wherein each leeboard comprises at least one upper element hinged to the fixed part and a lower element hinged to the upper element, so that the leeboards can be folded up towards the fixed part of the finkeel, to obtain overall dimensions smaller than the width of the hull.  
   
   
       2 . Finkeel according to  claim 1 , wherein the hinging axes of the upper elements and lower elements of the leeboards are parallel.  
   
   
       3 . Finkeel according to  claim 1 , wherein the hinging axis of the lower elements is perpendicular to the hinging axis of the upper elements.  
   
   
       4 . Finkeel according to  claim 1 , comprising means for rotating the upper elements and lower elements of the leeboards.  
   
   
       5 . Finkeel according to  claim 4 , wherein the means for rotating the elements which form the leeboards comprise gear mechanisms and/or hydraulic cylinders.  
   
   
       6 . Finkeel according to  claim 1 , wherein ballasts are attached at the ends of the leeboards.  
   
   
       7 . A boat comprising a finkeel according to  claim 1.
