What is the coverage area of the anchor light?

• A. 180 degrees
• B. 270 degrees
• C. 360 degrees
• D. 90 degrees

Answer: (C)

The anchor light must provide visibility in all directions to effectively alert other boaters of a vessel that is anchored. In most jurisdictions, the regulations require the anchor light to have a coverage of 360 degrees. This ensures that whichever direction another vessel approaches from, they will see the light, which serves as a navigation aid to prevent collisions. A 360-degree coverage allows for maximum visibility, particularly in crowded waters or during low-light conditions.

The other options reflect limited coverage areas, which would not adequately signal the presence of an anchored vessel from all angles. This is why the requirement for the anchor light is specifically designed for full-scope visibility.
