Hull with Delta Plate and Keel Extension

Abstract

A boat hull includes a bow, a stern and a bottom surface extending from said bow to said stern. Said bottom surface includes a substantially flat delta plate, and a keel extension extending, at least partially, across the delta plate.

What is claimed is: 
     
         1 . A boat hull comprising:
 a bow, a stern and a bottom surface extending from said bow to said stern, said bottom surface including a substantially flat delta plate, and a keel extension extending, at least partially, across the delta plate.   
     
     
         2 . The boat hull according to  claim 1 , further comprising a port side and a starboard side, the keel extension disposed along a centerline of the boat hull between the port side and the starboard side. 
     
     
         3 . The boat hull according to  claim 1 , wherein the delta plate has a triangle shape, the keel extension bisecting said triangle. 
     
     
         4 . The boat hull according to  claim 1 , wherein the delta plate is narrow fore and wider aft of the hull. 
     
     
         5 . A boat system comprising:
 a first boat having a hull, the hull including a bow, a stern and a bottom surface extending from said bow to said stern, said bottom surface including a delta plate that is substantially flat, and a keel extension extending, at least partially, across the delta plate; and   a parent boat, the parent boat including a notch, the first boat capable of sliding into and/or out of the notch for stowage and/or deployment of the first boat.   
     
     
         6 . The boat system according to  claim 5 , wherein the parent boat includes notch bunking for contacting the hull of the first boat, wherein when the first boat slides into and/or out of the notch, the keel extension reduces contact between the delta plate and the notch bunking. 
     
     
         7 . The boat system according to  claim 5 , wherein the first boat further includes a port side and a starboard side, the keel extension disposed along a centerline of the boat hull between the port side and the starboard side. 
     
     
         8 . The boat hull according to  5 , wherein the delta plate has a triangle shape, the keel extension bisecting said triangle. 
     
     
         9 . The boat hull according to  claim 5 , wherein the delta plate is narrow fore and wider aft of the hull. 
     
     
         10 . A method of stowing and/or deploying a first boat, the first boat having a hull, the hull including a bow, a stern and a bottom surface extending from said bow to said stern, said bottom surface including a delta plate that is substantially flat, and a keel extension extending, at least partially, across the delta plate; and
 sliding the first boat into and/or out of a notch of a parent boat so as to stow and/or deploy the first boat, respectively.   
     
     
         11 . The method according to  claim 10 , wherein the parent boat includes notch bunking for contacting the hull of the first boat, wherein sliding the first boat into and/or out of the notch includes placing the keel extension into contact with the notch bunking, reducing contact between the delta plate and the notch bunking. 
     
     
         12 . The method according to  claim 10 , wherein the first boat further includes a port side and a starboard side, the keel extension disposed along a centerline of the boat hull between the port side and the starboard side. 
     
     
         13 . The boat hull according to  10 , wherein the delta plate has a triangle shape, the keel extension bisecting said triangle. 
     
     
         14 . The boat hull according to  claim 10 , wherein the delta plate is narrow fore and wider aft of the hull.
