If you anchor your 25-meter vessel in a harbor, what light(s) must you show?

• A. No lights
• B. One all-round white light
• C. Two all-round white lights
• D. A white light and a red light

Answer: (B)

When a vessel is at anchor, the signal you must show is a single all-round white light. This anchor light is placed so it can be seen from all directions and communicates to other vessels that you are stationary and anchored. It helps prevent collisions in busy harbors by marking your position at night or in reduced visibility. The red/green sidelights and stern light are for vessels that are moving; they aren’t used when you’re anchored. So for a 25-meter vessel moored in a harbor, one all-round white light is the correct signal.
