Method and apparatus for displaying azimuth of marine vessel, marine vessel, and storage medium

A marine vessel comprising:

• a display:
• at least one memory to store a set of instructions;
• and
• at least one processor configured or programmed to:
• acquire a speed of a marine vessel and an azimuth of the marine vessel;
• and
• display on the display a mark based on the acquired speed and the acquired azimuth;
• wherein
• 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.

An azimuth display apparatus comprising:

• a display to display an azimuth of a marine vessel;
• at least one memory to store a set of instructions;
• and
• at least one processor configured or programmed to:
• acquire a speed of a marine vessel and an azimuth of the marine vessel;
• and
• display on the display a mark based on the acquired speed and the acquired azimuth;
• wherein
• 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.

A non-transitory storage medium storing a program to cause a computer to execute a method for displaying an azimuth of a marine vessel, the method comprising:

• acquiring a speed of a marine vessel and an azimuth of a marine vessel;
• and
• displaying on a display a mark based on the acquired speed and the acquired azimuth;
• wherein
• 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.
