BOTH INTERNATIONAL & INLAND What would a vessel towing a barge show at the stern of the tow vessel?

Correct Answer: Option D — a towing light above the stern light

Rule 24(c) dictates that a power-driven vessel towing astern must exhibit a towing light in a vertical line above the stern light. This configuration allows following vessels to distinguish the towing vessel from a standard power-driven vessel and alerts them to the presence of a tow astern.
