What does the solid line on an AIS target symbol indicate?

• A. Speed over ground (SOG)
• B. Course over the ground (COG)
• C. Current position accuracy
• D. Ship's heading

Answer: (B)

The solid line on an AIS target symbol indicates the course over the ground (COG). This visual representation reflects the actual direction in which a vessel is moving over the surface of the water, taking into account any influence of wind, tide, or current. The COG is essential for navigators as it provides clear guidance on the vessel's intended travel direction, crucial for ensuring safe navigation and avoiding collisions. Understanding the COG is particularly important in maritime navigation, where various factors can affect a vessel’s path. By observing COG through the solid line, navigators can make informed decisions about their own courses and adjust as necessary to maintain safe distances from other vessels.
