Electrically powered surfboard

Abstract

Conventional unpowered surfboards enable riders to catch and ride waves towards a shoreline and experience the thrill and power of ocean waves. An electric powered surfboard has been developed to assist novice riders or riders who have suffered injuries or impairments which limit their ability to paddle are effectively prevented, or at least impaired from enjoying this activity. The surfboard comprises one or more propulsion systems which each comprise an electric motor, a drive shaft and a rotor. The rotor may be a propeller mounted in a fin of the board, or it may be an impellor in a water jet. The surfboard also comprises a power control system for controlling power to the propulsion system and comprises a speed controller and a battery as well as a cooling system for cooling the motor and speed controller. The surfboard may also comprise a monitoring system which comprises a power monitor and an output device for indicating the remaining capacity to the rider. This has the advantage of improved reliability as well as informing the user of their use and remaining capacity to ensure they are able to safely return to the shore.
