BOTH INTERNATIONAL & INLAND Which light(s) will be visible to a vessel overtaking another vessel?

Correct Answer: Option C — only the stern light of the vessel

Rule 13 defines an overtaking situation as one where a vessel approaches another from a direction more than 22.5 degrees abaft her beam. At night, the overtaking vessel will see only the stern light of the vessel being overtaken, as the sidelights and masthead lights are not visible.
