Propulsion system for assistance when paddling in surfing

Abstract

Propulsion system for assistance when paddling in surfing; comprising a propellant device (1), hydro jet type, intended to be mounted on a surfboard (T); and a control device (2) in the manner of a bracelet or bracelet suitable for its attachment on a users arm. The control device (2) comprises: —a microprocessor (21), —a supply battery (22), —sensors (23) that provide the microprocessor (21) with suitable data to identify the users rowing action, calculating the speed and intensity of paddling and generating a control signal proportional to the paddling intensity of the user and; —a wireless communication means (24) that transmits the control signal to the propelling device (1); and wherein said propelling device (1) varies the propulsion power as a function of the signals received from the control device (2).
