• an electric motor for driving the propeller in rotation, the axis of rotation of which is coaxial with the longitudinal axis of the stick, - a system, such as a battery, for supplying energy to the engine,
• the handle is a telescopic handle formed of tubes mounted in sliding interlocking for the displacement of the tubes between a retracted position of shorter length of the handle and a telescopic extension position of greater length of the handle, the tubes being respectively equipped one, said lower tube, with the propeller, the other, said upper tube, with the engine control system, in that the power supply system is positioned in the upper tube and the motor in the lower tube and in that the power supply system is connected to the motor by a wired link arranged inside the handle.
• the design of a telescopic handle as described above makes it possible to avoid removing the handle for storage of the device. This arrangement also allows an optimization of the weight distribution. Finally, this construction improves the buoyancy of the device in the telescopic extension position of the handle tubes.
• the wire link comprises at least one spiral cable.
• the presence of the turns allows an easy variation of the length of the cable by simple deformation of the turns, especially when the handle passes from a retracted position of the tubes corresponding to the smallest length of the handle to an extended position of telescopic extension of the tubes corresponding to the longest length of the handle.
• control system is carried by the handle having an axial gripping part, coaxial with the handle.
• the propeller has two directions of rotation and the control system comprises at least one trigger
• the propeller is at least partially protected by a fairing and the device comprises blades, called radial blades for connecting the handle to the fairing of the propeller.
• the presence of blades can allow the use of the propulsion device in the manner of an oar.
• said so-called anti-torque blades are configured to prevent rotation of the handle on itself in the state. driven in rotation of the propeller. This results in less muscle fatigue for the operator, this muscle fatigue being already reduced due to the weight distribution of the handle.
