BOTH INTERNATIONAL & INLAND At night, a barge being towed astern must display which light(s)?

Correct Answer: Option C — sidelights and a stern light

Rule 24(h) mandates that a vessel or object being towed must exhibit sidelights and a stern light. These lights are the standard requirement for towed vessels to ensure they are properly identified by other vessels, regardless of whether they are manned or unmanned, to prevent collisions at night.
