Pontoon boat having improved buoyancy

Abstract

A pontoon boat is shown which includes a frame, and a plurality of pontoons attached to the frame. The plurality of pontoons comprises two outer pontoons of substantially cylindrical configuration and a center pontoon comprising a substantially curvilinear configuration, wherein a height of the center pontoon is substantially equal to the diameter of the outer pontoons. One embodiment of the pontoon is elliptical in cross section.

 a frame;   a plurality of pontoons attached to the frame; and   wherein at least one of said pontoons is substantially elliptical in cross-section.   
   
   
       2 . The pontoon boat of  claim 1 , wherein the plurality of pontoons is two pontoons, and both of said pontoons are elliptical in cross-section. 
   
   
       3 . The pontoon boat of  claim 1 , wherein the plurality of pontoons is three pontoons, and one of said pontoons is elliptical in cross-section. 
   
   
       4 . The pontoon boat of  claim 3 , wherein the plurality of pontoons comprises two outer substantially cylindrical pontoons, and a center elliptical pontoon. 
   
   
       5 . The pontoon boat of  claim 4 , wherein the minor axis of the center elliptical pontoon is substantially equal to the diameter of the two outer pontoons. 
   
   
       6 . The pontoon boat of  claim 5 , wherein the diameter of the two outer pontoons and the minor axis of the center elliptical pontoon is about 25″. 
   
   
       7 . The pontoon boat of  claim 6 , wherein the major axis of the center elliptical pontoon is about 32″. 
   
   
       8 . A pontoon boat, comprising:
 a frame;   a plurality of pontoons attached to the frame, the plurality comprising two outer pontoons of substantial cylindrical configuration and a center pontoon comprising a substantially closed tube of curvilinear configuration.   
   
   
       9 . The pontoon boat of  claim 8 , wherein said center pontoon is elliptical in cross-section. 
   
   
       10 . The pontoon boat of  claim 9 , wherein the minor axis of the center elliptical pontoon is substantially equal to the diameter of the two outer pontoons. 
   
   
       11 . The pontoon boat of  claim 10 , wherein the diameter of the two outer pontoons and the minor axis of the center elliptical pontoon is about 25″. 
   
   
       12 . The pontoon boat of  claim 11 , wherein the major axis of the center elliptical pontoon is about 32″. 
   
   
       13 . The pontoon boat of  claim 8 , further comprising a deck mounted on the top side of said frame, said deck and said center pontoon having an opening therethrough profiled as a storage area. 
   
   
       14 . A pontoon boat, comprising:
 a frame;   a plurality of pontoons attached to the frame, comprising two outer pontoons of substantially cylindrical configuration and a center pontoon comprising a substantially curvilinear configuration, wherein a height of said center pontoon is substantially equal to the diameter of said outer pontoons.   
   
   
       15 . The pontoon boat of  claim 14 , wherein the center pontoon is comprised of a substantially closed tube along at least a portion of a length. 
   
   
       16 . The pontoon boat of  claim 15 , further comprising a deck mounted on the top side of said frame, said deck and said center pontoon having an opening therethrough profiled as a storage area. 
   
   
       17 . The pontoon boat of  claim 14 , wherein said center pontoon is elliptical in cross-section. 
   
   
       18 . The pontoon boat of  claim 17 , wherein the minor axis of the center elliptical pontoon is substantially equal to the diameter of the two outer pontoons. 
   
   
       19 . The pontoon boat of  claim 18 , wherein the diameter of the two outer pontoons and the minor axis of the center elliptical pontoon is about 25″. 
   
   
       20 . The pontoon boat of  claim 18 , wherein the major axis of the center elliptical pontoon is about 32″.
