What does the symbol representing a vessel heading indicate on an AIS display?

• A. The speed of the vessel
• B. The current position of the vessel
• C. The intended course of the vessel
• D. The movement direction of the vessel

Answer: (D)

The symbol that represents a vessel's heading on an AIS (Automatic Identification System) display provides information about the direction in which the vessel is currently moving. This symbol typically shows the instantaneous movement direction, which is crucial for navigation and collision avoidance. Understanding the heading helps mariners assess their own vessel's trajectory and is essential for situational awareness, particularly in busy or navigationally challenging environments. By focusing on the current movement direction, mariners can make informed decisions, adjust their navigation plans, and ensure safe passage while interacting with other vessels. This functionality is particularly vital for the effective use of ECDIS, as it allows for real-time assessment of navigational risks and helps in establishing appropriate responses to maintain safety at sea.
