<p>An automatic fixed point holding system for marine vessels can automatize control of turning angle and thrust of a turning type propeller for holding of position and azimuth of a marine vessel. A standard state for a plurality of turning type propellers provided at both ends of a hull (1) is set such that a thrust direction (a) is directed toward the center (1a) of the hull, and control for decreasing adjustment of a turning angle (thrust direction) of each of the pushers (2) from the standard state and holding position and orientation of the hull (1) mainly by adjustment of a magnitude of thrust is automatically effected in response to detection signals from a hull position measuring device and a hull azimuth sensor.</p> |
