Vessel Hull

Abstract

A vessel hull having a pair of vents formed in the chine on each side for allowing air to be introduced to the bottom and a pair of downwardly extending fins formed longitudinally along the chine adjacent to each vent. Each vent can be formed by a recess in the chine dividing the chine into a forward portion and an aft portion. Each fin is preferably formed longitudinally along the aft portion of the chine and extends below the waterline. The fins counterbalance the removal of a portion of the chine to vent the bottom and increase stability during turns. The hull preferably also includes a pair of chine extensions projecting aft of the transom on each side for reducing or eliminating side-to-side oscillation of the stern when the hull is propelled through the water at slow speeds.

1 . A boat hull, having a bow and a stern capable of moving through a body of water, wherein the improvement comprises a chine extension aft at each side of said stern, wherein said chine extension projects longitudinally rearward from said stern.  
   
   
       2 . The boat hull, according to  claim 1 , wherein said chine extension is integrally molded into said boat hull.  
   
   
       3 . The boat hull, according to  claim 1 , wherein said chine extension is manufactured separately from the hull and is then affixed to said boat hull.  
   
   
       4 . The boat hull, according to  claim 1 , wherein said extension is arched along the horizontal, wherein the widest point of said arch is adjacent to said boat hull.  
   
   
       5 . The boat hull, according to  claim 1 , wherein said extension is semi-arched along the horizontal, wherein the widest point of said arch is adjacent to said boat hull.  
   
   
       6 . The boat hull, according to  claim 1 , wherein said extension has a fore to aft length of about  ⅞ inches to about    1¾ inches for a boat hull having a bow to stern length of about  10 feet to about 40 feet.  
   
   
       7 . The boat hull, according to  claim 1 , wherein the port-to-starboard width of said extension at the point closest to said boat hull is about  3¼ inches to about    4½ inches for a boat hull having a bow to stern length of about  10 feet to about 40 feet.
