Battery Powered, Center Mounted, Motorized Stand Up Paddle Board System

摘要

Conversion of a stand up paddle (SUP) board or similar personal watercraft to enable it to be powered by a battery and an electric motor and propeller apparatus requires a practical and performance oriented configuration to be successful. This patent describes an optimal configuration that utilizes a vertical hollow protrusion through the stand up paddle board that supports the propulsion system and is comprised of two assemblies; a motor and propeller assembly, and a battery and control assembly. The location of the hollow protrusion on the board is a critical feature of this invention. Placing the hollow protrusion in a central location on the board mitigates, to the greatest extent possible, the negative aspects of propelling the board with a propeller and the extra weight of the motorized system on the board's balance and maneuverability characteristics. This is accomplished by locating the hollow protrusion and equipment associated with the motorized system relatively close to, and forward of the rider. This allows the rider to efficiently counterbalance the weight of the motorized system and effectively manage the forward thrust provided by propulsion. This invention allows battery powered, motorized stand up paddle boarding to be developed into an affordable, attractive and performance oriented recreational sport.
