The center of the screen represents the position of your what?

• A. Vessel
• B. Target
• C. Origin
• D. GPS

Answer: (A)

On most navigation screens used aboard a vessel, your own ship is shown at the center. The display then plots other vessels, land, and navigational objects around you based on their range and bearing from that central point. Keeping your vessel at the center makes it easy to judge how close others are and which direction they’re coming from or going to, which is essential for safe maneuvering and collision avoidance. GPS is the system that determines positions, but the screen centers on your vessel to provide a stable reference point for relative targets. Therefore, the center represents your vessel’s position.
