BOTH INTERNATIONAL & INLAND Which light(s) is/are required by a 200-meter vessel at anchor?

🔍 Key Concepts

• Rule 30 – Anchored Vessels and Vessels Aground (Navigation Rules) • Difference between masthead, stern, and all-round white lights (arcs of visibility: 225°, 135°, 360°) • Special requirement for vessels 100 meters or more at anchor

💭 Think About

• First decide: at anchor, do you show directional running lights (port, starboard, stern) or all‑round anchor lights? • Think about what the lookout on another vessel should be able to tell when seeing an anchored vessel: do they need to know the ship’s heading, or simply that it is anchored and very large? • Compare the arc of visibility in each option (135° vs 225°) with what an anchor light is supposed to show.

✅ Before You Answer

• Check Rule 30 to see what color and type of light is required for a vessel at anchor. • Verify whether a 200‑meter vessel needs one or two white lights, and where they must be placed (fore and aft, and which is higher). • Confirm if using working/deck lights alone satisfies the specific anchor light requirement or if they are only an additional option for large vessels.
