Abstract
A method and apparatus to reduce or prevent misrecognition of an actual azimuth of a marine vessel includes acquiring a speed of the marine vessel and an azimuth of the marine vessel, and displaying a mark on a display based on the acquired speed and the acquired azimuth. The mark is displayed so as to allow the azimuth of the marine vessel to be determined in a case that the speed of the marine vessel exceeds a first predetermined speed, and the mark is displayed so as to not allow the azimuth of the marine vessel to be determined in a case that the speed of the marine vessel does not exceed the first predetermined speed.
