BOTH INTERNATIONAL & INLAND A vessel towing astern is severely restricted in its ability to maneuver. Which lights shall it exhibit while underway?

Correct Answer: Option D — All of the above

Rule 27(b) requires a vessel restricted in her ability to maneuver (RAM) to display the lights prescribed in Rule 24 for a towing vessel, in addition to the three all-round lights (red-white-red). This ensures the vessel signals both its towing status and its restricted maneuverability to other traffic.
