A barge more than 50 meters in length would be required to show how many white anchor lights when anchored in a Secretary of Transportation approved 'special anchorage area'?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

When a vessel is at anchor, it must show lights to signal its presence to other ships. In a Secretary of Transportation approved special anchorage area, the rule increases visibility for larger vessels. Specifically, a barge longer than 50 meters must display two white anchor lights arranged in a vertical line, rather than just a single light. This setup helps other mariners gauge the vessel’s size and position more clearly from all directions. So, the required number of white anchor lights in that scenario is two.
