A device for the erection of the mast of a sailing board adapted for use in the sport of windsurfing includes an articulated joint in which separate members are kept coupled together by means of a system comprising a flexible rope and a spring, where a displacement of the mast from the vertical attitude causes the loading of the spring thus creating a force tending to bring the mast back to a vertical attitude. The device may be assembled on a track that allows a change in the position of the foot of the mast through the operation of a pedal.
