Q

BOTH INTERNATIONAL & INLAND A vessel is overtaking when she can see which light(s) of a vessel ahead?

🔍 Key Concepts

• Rule 13 – Overtaking in the Navigation Rules • Relative bearing of the overtaking vessel (more than 22.5° abaft the beam) • Which navigation lights are visible from astern vs. from ahead or on the beam

💭 Think About

• Think about where an overtaking vessel is located relative to the other vessel’s beam. From that position, which lights are designed to be visible? • Review the arcs of visibility for sidelights, masthead lights, and stern lights. Which light(s) can you see if you are coming from almost directly behind another vessel? • Compare the angles that sidelights cover with the angle that the stern light covers. In an overtaking situation, are you within the sidelights’ sector or the stern light’s sector?

✅ Before You Answer

• Verify the arcs of visibility for sidelights (port and starboard), masthead light(s), and stern light in the Navigation Rules Annex I or lighting section. • Confirm that in an overtaking situation the bearing is more than 22.5° abaft the beam of the vessel being overtaken. • Make sure the light(s) you choose are those that are intended to be visible from astern, not primarily from ahead or on the bow/beam.
