Box shaped bilge keel

Abstract

A box shaped bilge keel comprises a convex polygonal shaped cross-section. Further, the box shaped bilge keel extends along a pre-determined length of a hull of a floating vessel. Also, the box shaped bilge keel is providing additional width to the hull at the bottom of the floating vessel.

1 . A box shaped bilge keel of a floating vessel, the box shaped bilge keel comprising a convex polygonal shaped cross-section, wherein the box shaped bilge keel extends along a pre-determined length of a hull of the floating vessel. 
     
     
         2 . The box shaped bilge keel as claimed in  claim 1 , wherein the convex polygonal shaped cross-section is extending along the length of the hull, in a continuous manner. 
     
     
         3 . The box shaped bilge keel as claimed in  claim 1 , wherein the convex polygonal shaped cross-section is extending along the length of the hull, in form of a plurality of discontinuous segments. 
     
     
         4 . The box shaped bilge keel as claimed in  claim 1 , wherein the cross-section of the bilge keel is square. 
     
     
         5 . The box shaped bilge keel as claimed in  claim 1 , further comprising two tapered sections, one at each of a forward end and an aft end of the hull, respectively.
