Widened base of a boat keel

Abstract

This invention relates to a widened base of a boat keel, notably the base of any keel intended to equip a catamaran-type boat. The skate ( 3 ) is prepared separately but mounted and firmly affixed under the keel ( 2 ) of a hull ( 1 ) by simple means. The separate skate ( 3 ) is mounted under the keel ( 2 ) and can easily be removed by means of vertical screws passing through the skate ( 3 ) and screwing into holes drilled into the bottom of the keel ( 2 ).

What is claimed:  
     
         1 . A widened base for a boat keel, notably the base of any keel intended to equip a catamaran-type boat, the keel having a bottom further comprising a skate prepared separately but mounted and firmly affixed under the keel of a boat hull by simple means.  
     
     
         2 . The widened keel base of  claim 1 , wherein the separate skate is mounted under the keel and can be easily removed by means of vertical screws passing through the skate and screwing into holes drilled into the bottom of the keel.  
     
     
         3 . The widened keel base of  claim 1 , wherein the skate further comprises a surface that has been coated with a reflective material for easier detection of the boat when the boat capsizes.  
     
     
         4 . The widened keel base of  claim 2 , wherein the separate skate is wider than the bottom of the keel and further comprises an upper surface including a center part that matches the shape of said bottom and is bordered, on either side of said bottom, by longitudinal edges.  
     
     
         5 . The widened keel base of  claim 4 , wherein the separate skate has a series of holes longitudinally aligned along the center of said center part facing holes drilled into said bottom, through which the screws pass.  
     
     
         6 . The widened base of  claim 1 , wherein the separate skate, seen in profile, has a variable thickness such that its bottom surface is straight, regardless of the profile of said bottom of the keel.
