Abstract: The present invention relates to a mounting device (30) for a joystick (10), the mounting device (30) comprising a first and second mounting element (32, 34), a spring element (36) and a ball element (38). The two mounting elements (32, 34) are rotatably attached to allow rotation of the joystick (10) about a central axis (22) of yaw rotation. The spring element (36) is mounted to the first mounting element (32) and urges the ball element (38) against a ball support surface (50) of the second mounting element (34). The ball support surface (50) is inclined such that rotation of the stick element (16) about the central axis (22) away from a neutral yaw position causes increase of tension in the spring element (36), biasing the joystick (10) towards the neutral yaw position. Further, the invention relates to a joystick (10) and a marine vessel.
