Method and apparatus in an electric propulsion arrangement of a sailing vessel

A method in an electric propulsion arrangement of a sailing vessel, wherein the sailing vessel has a traction device provided with an electric motor and with a propeller mechanism, the electric motor of which traction device being usable in forward drive and reverse drive, the electric motor further being usable as a generator during sailing, for charging one or more accumulators of the sailing vessel, and wherein the propeller mechanism of the traction device includes a propeller hub with a plurality of propeller blades being adjustably positioned to plural pitch angles, a hollow propeller shaft fixed at a first end to the propeller hub, having a center axis, and a second end, a control shaft having an adjustable position and controlling the pitch angles of the propeller blades being inside the propeller shaft, and an actuator actuating the control shaft, the method comprising:

• changing the position of the control shaft in relation to the propeller shaft, and in which method the propeller shaft is supported and rotated around its center axis from a section between the first and the second end of the propeller shaft,
• adjusting the pitch angles of the propeller blades by control of the actuator, the actuator being fixed to the second end of the propeller shaft to be rotatable along with the propeller shaft by rotating the control shaft inside the propeller shaft in relation to the propeller shaft.
