BOTH INTERNATIONAL & INLAND You are overtaking a vessel at night and you see a yellow light showing above the stern light of the overtaken vessel. Which is TRUE of the vessel being overtaken?

Correct Answer: Option B — towing astern

Rule 24(c) requires a vessel towing astern to display a yellow towing light above the stern light. Seeing this specific vertical arrangement of lights at night identifies the vessel as one engaged in towing astern, necessitating caution due to the tow line extending behind the vessel.
