What does the dashed line in an AIS target symbol represent?

• A. The vessel's speed
• B. The vessel's position
• C. The vessel's heading
• D. The vessel's destination

Answer: (C)

The dashed line in an AIS (Automatic Identification System) target symbol is an important feature used to convey navigational information regarding the vessel's heading. This line represents the predicted path of the vessel based on its current heading and speed. It is often referred to as a "vector" and extends in the direction the vessel is moving, providing a visual cue for mariners to assess the vessel's trajectory over time. Understanding the vessel's heading is crucial for navigation and collision avoidance, as it allows operators to anticipate where a vessel is likely to be in the near future. The effectiveness of the AIS system is enhanced by this visual representation, which aids in situational awareness for those navigating in congested waters or near other vessels. In contrast, the other options do not accurately reflect what the dashed line signifies. Speed, position, and destination are critical elements of a vessel's navigation data but are represented differently within the AIS system and do not involve the dashed line symbol.
