🔍 Key Concepts

• Anchor lights requirements for power-driven and sailing vessels at anchor • Length thresholds in the Navigation Rules (COLREGS and Inland) for one vs. two all-round white lights at anchor • Difference between a small vessel at anchor and a larger vessel that must show a forward and aft anchor light

💭 Think About

• Think about what changes when a vessel becomes large enough that a single all-round white light is not considered sufficient for other vessels to judge its size and orientation. • Recall the Rule that describes anchor lights: what does it say about vessels less than a certain length versus vessels equal to or greater than that length? • Visualize a large ship at anchor at night: where are the anchor lights placed and why would two be required instead of one?

✅ Before You Answer

• Verify in the Anchored Vessels rule (Lights and Shapes) the exact length at which a second all-round white light is required. • Check whether the smaller length category says a vessel "may" or "shall" show additional anchor lights—wording matters. • Confirm that the same length threshold applies to both International and Inland rules for this requirement.
