BOTH INTERNATIONAL & INLAND The tug shown in illustration D024RR below is greater than 50 meters and severely restricted in her ability to deviate from her course. Which lights would be displayed from the towing vessel?

Correct Answer: Option D — None of the above

Rule 27(b) defines a vessel restricted in her ability to maneuver. A towing vessel in this condition must display three all-round lights in a vertical line (red-white-red) and masthead lights as required by Rule 24. None of the provided options correctly list the full, required combination of these specific lights.
