Paddle Board With Internal Propulsion Drive

Abstract

A stand-up paddle board having an elongated hull, an internal housing structure formed within the hull, and an electric motor positioned within the internal housing and configured to drive an impeller so as to pull water in through a water inlet and force the water out through an exhaust nozzle so as to propel the stand-up paddle board through the water.

What is claimed is: 
     
         1 . A stand-up paddle board comprising:
 an elongated hull;   an internal housing structure formed within the hull and having a water inlet and an exhaust nozzle; and   an electric motor positioned in the internal housing and configured to drive an impeller so as to pull water in through said water inlet and force the water out through the exhaust nozzle so as to propel the paddle board through the water.   
     
     
         2 . The stand-up paddle board of  claim 1  wherein said internal housing structure comprises a battery and motor controller compartment, a drive system housing, and a collector. 
     
     
         3 . The stand-up paddle board of  claim 2  wherein the electric motor is positioned within said drive system housing. 
     
     
         4 . The stand-up paddle board system of  claim 3  further comprising a motor controller positioned in said internal housing. 
     
     
         5 . The stand-up paddle board of  claim 4  further comprising at least one spacer positioned in said drive housing between said electric motor and said motor controller. 
     
     
         6 . The stand-up paddle board of  claim 1  wherein said internal housing structure is formed or molded within said hull during manufacture so as to permanently fix the internal housing structure within the hull. 
     
     
         7 . The stand-up paddle board of  claim 5  wherein said internal housing structure is formed or molded within said hull during manufacture so as to permanently fix the internal housing structure within the hull. 
     
     
         8 . The stand-up paddle board of  claim 1  further comprising a tail fin having a flexible section enabling the fin to be folded for storage.
