Buoyancy vehicle

Abstract

A buoyancy vehicle operable to navigate on a fluid from a sitting and reclined position. The vehicle provides facilitated access and operational control to propulsion and navigational systems that can be operated from a sitting or reclined position. Consequently, a user who cannot stand or perform rigorous physical activity may operate the buoyancy vehicle. The buoyancy vehicle comprises at least one buoyant member configured to float on the fluid with sufficient buoyancy to support the vehicle and the operator. A frame portion attaches to the buoyant member. The frame portion is generally tubular and sufficiently lightweight and/or hollow, so as to enhance the buoyancy of the vehicle. A center board retractably extends from a bottom surface of the frame portion. A seat is configured to support an operator and/or a load, and enable easy access to the navigational and propulsion systems for operating the vehicle.

What is claimed is: 
     
         1 . A vehicle comprising:
 at least one buoyant member configured to at least partially support said vehicle while floating;   a frame portion disposed to join with said at least one buoyant member, said frame portion configured to at least partially provide structural integrity and buoyancy to said vehicle;   a propulsion portion configured to at least partially propel and navigate said vehicle; and   a seat disposed to join with said frame portion, said seat configured to enable at least partial operation of said propulsion portion from a sitting and/or reclined position.   
     
     
         2 . The vehicle of  claim 1 , in which said vehicle comprises a lightweight boat. 
     
     
         3 . The vehicle of  claim 2 , in which said at least one buoyant member comprises a pair of surfboards adjacently spaced from each other. 
     
     
         4 . The vehicle of  claim 3 , in which said frame portion comprises a plurality of tubular frames. 
     
     
         5 . The vehicle of  claim 4 , in which said plurality of tubular frames comprises hollow tubes. 
     
     
         6 . The vehicle of  claim 5 , in which said frame portion joins with said at least one buoyant member through at least one frame junction. 
     
     
         7 . The vehicle of  claim 6 , in which said at least one frame junction comprises a threaded connection between said frame portion and said at least one buoyant member. 
     
     
         8 . The vehicle of  claim 7 , in which said vehicle comprises a center board. 
     
     
         9 . The vehicle of  claim 8 , in which said vehicle comprises a center board cord configured to join said center board with said frame portion. 
     
     
         10 . The vehicle of  claim 9 , wherein said center board helps said vehicle compensate for rising and lowering fluid levels. 
     
     
         11 . The vehicle of  claim 10 , in which said seat comprises a hinge disposed to join with said plurality of tubular frames. 
     
     
         12 . The vehicle of  claim 11 , wherein said hinge is configured to enable said seat to at least partially swivel, pivot, and adjust in height. 
     
     
         13 . The vehicle of  claim 12 , in which said seat comprises a fastening end configured to join with a seat fastener on said frame portion. 
     
     
         14 . The vehicle of  claim 13 , in which said propulsion portion comprises a draft conversation portion and/or a paddle. 
     
     
         15 . The vehicle of  claim 14 , in which said draft conversation portion comprises a rear curved section configured to enhance conversation of a draft. 
     
     
         16 . The vehicle of  claim 15 , in which said draft conversation portion comprises a sail, said sail configured to be controlled by a mast and a sail cord, said mast comprising a mast control portion configured to enable at least partial operation of said mast from said sitting and/or reclined position. 
     
     
         17 . The vehicle of  claim 16 , in which said sail joins a dowel at a plurality of connection junctions. 
     
     
         18 . The vehicle of  claim 17 , in which said sail comprises a transparent portion configured to enable at least partial viewing through said sail. 
     
     
         19 . A vehicle comprising:
 means for floating at least one buoyant member on a fluid;   means for supporting said vehicle;   means for compensating for rising and lowering fluid with a center board;   means for joining a seat with a frame portion;   means for sitting and/or reclining, by an operator, on the seat   means for manipulating said seat; and   means for at least partially operating a propulsion portion from said sitting and/or reclining position.   
     
     
         20 . A vehicle consisting of:
 at least one buoyant member configured to at least partially support said vehicle while floating, said at least one buoyant member comprising a pair of surfboards adjacently spaced from each other;   a frame portion disposed to join with said at least one buoyant member, said frame portion configured to at least partially provide structural integrity and buoyancy to said vehicle, said frame portion comprising a plurality of tubular frames, said plurality of tubular frames comprises a hollow tube;   a propulsion portion configured to at least partially propel and navigate said vehicle, said propulsion portion comprises a draft conversation portion and/or a paddle, said draft conversation portion comprising a sail, said sail configured to be controlled by a mast and a sail cord, said mast comprising a mast control portion configured to enable at least partial operation of said mast from said sitting and/or reclined position; and   a seat disposed to join with said frame portion, said seat configured to enable at least partial operation of said propulsion portion from a sitting and/or reclined position, said seat comprising a hinge disposed to join with said plurality of tubular frames, said hinge configured to enable said seat to at least partially swivel, pivot, and adjust in height.
