Watercraft hull

Abstract

A hull for a watercraft has a port side, a starboard side, and a keel disposed between the port side and the starboard side. Each of the port and starboard sides has a first portion having a first deadrise angle, and a second portion having a second deadrise angle. The first portion is disposed laterally between the second portion and the keel. A first chine is connected to the first portion. The first portion is disposed laterally between the keel and the first chine. A second chine is connected to the second portion. The second portion is disposed laterally between the first chine and the second chine. The second chine is a soft chine. The first chine has a smaller radius of curvature than the second chine.

         1 . A hull for a watercraft comprising:
 a port side;   a starboard side; and   a keel disposed between the port side and the starboard side, each of the port and starboard sides comprising:
 a first portion having a first deadrise angle; 
 a second portion having a second deadrise angle, the first portion being disposed laterally between the second portion and the keel; 
 a first chine connected to the first portion, the first portion being disposed laterally between the keel and the first chine; and 
 a second chine connected to the second portion, the second portion being disposed laterally between the first chine and the second chine, the second chine being a soft chine. 
   
     
     
         2 . The hull of  claim 1 , wherein, for each of the port and starboard sides, the first chine is a hard chine. 
     
     
         3 . The hull of  claim 1 , wherein the hull has a length, and wherein for each of the port and starboard sides, the first and second chines extend parallel to each other on at least a portion of the length of the hull. 
     
     
         4 . The hull of  claim 1 , wherein, for each of the port and starboard sides, at least one of the first and second portions is uninterrupted. 
     
     
         5 . The hull of  claim 1 , wherein, for each of the port and starboard sides, the first deadrise angle and the second deadrise angle are identical. 
     
     
         6 . The hull of  claim 1 , wherein, for each of the port and starboard sides, at least one of the first and second chines is uninterrupted and extends on a majority of a length of the hull. 
     
     
         7 . The hull of  claim 1 , wherein, for each of the port and starboard sides, when seen from the port and starboard sides, at least one of the first and second chines is generally parallel to a waterline of the hull. 
     
     
         8 . The hull of  claim 1 , wherein, for each of the port and starboard sides, the hull further comprises a third portion and a third chine, the first chine connecting the third portion to the first portion, the third chine connecting the third portion to the second portion, the third portion having a third deadrise angle, the third deadrise angle being different from the first and second deadrise angles. 
     
     
         9 . The hull of  claim 1 , wherein, for each of the port and starboard sides a reverse chine is connected to the second chine, the second chine being disposed laterally between the second portion and the reverse chine. 
     
     
         10 . A watercraft comprising:
 a hull, the hull having port and starboard sides and a keel disposed therebetween;   a deck disposed on the hull;   an engine connected to at least one of the hull and the deck;   a propulsion system operatively connected to the engine,   each of the port and starboard sides comprising:
 a first portion having a first deadrise angle; 
 a second portion having a second deadrise angle, the first portion being disposed laterally between the second portion and the keel; 
 a first chine connected to the first portion, the first portion being disposed laterally between the keel and the first chine; and 
 a second chine connected to the second portion, the second portion being disposed laterally between the first chine and the second chine, the second chine being a soft chine. 
   
     
     
         11 . The watercraft of  claim 10 , wherein, for each of the port and starboard sides, the first chine is a hard chine. 
     
     
         12 . The watercraft of  claim 10 , wherein the watercraft has a length, and wherein for each of the port and starboard sides the first and second chines extend parallel to each other on at least a portion of the length of the hull. 
     
     
         13 . The watercraft of  claim 10 , wherein, for each of the port and starboard sides, at least one of the first and second portions is uninterrupted. 
     
     
         14 . The watercraft of  claim 10 , wherein for each of the port and starboard sides the first deadrise angle and the second deadrise angle are identical. 
     
     
         15 . The watercraft of  claim 10 , wherein, for each of the port and starboard sides, at least one of the first and second chines is uninterrupted and extends on a majority of a length of the hull. 
     
     
         16 . The watercraft of  claim 10 , wherein, for each of the port and starboard sides, when seen from the port and starboard sides, at least one of the first and second chines is generally parallel to a waterline of the hull. 
     
     
         17 . The watercraft of  claim 10 , wherein, for each of the port and starboard sides, the hull further comprises a third portion and a third chine, the first chine connecting the third portion to the first portion, the third chine connecting the third portion to the second portion, the third portion having a third deadrise angle, the third deadrise angle being different from the first and second deadrise angles. 
     
     
         18 . The hull of  claim 10 , wherein, for each of the port and starboard sides, the hull further comprises a reverse chine connected to the second chine, the second chine being disposed laterally between the second portion and the reverse chine. 
     
     
         19 . A hull for a watercraft comprising:
 a port side;   a starboard side; and   a keel disposed between the port side and the starboard side, each of the port and starboard sides comprising:
 a first portion having a first deadrise angle; 
 a second portion having a second deadrise angle, the first portion being disposed laterally between the second portion and the keel; 
 a first chine connected to the first portion, the first portion being disposed laterally between the keel and the first chine; and
