BOTH INTERNATIONAL & INLAND The tow shown in illustration D024RR below is greater than 200 meters in length and severely restricts the tow vessel's ability to deviate from her course. Which day shape(s) would be displayed by day from the vessel(s)?

Correct Answer: Option D — All of the above

Per COLREG Rule 27 and Rule 24, a vessel engaged in a towing operation with a tow length exceeding 200 meters and restricted in her ability to maneuver must exhibit shapes for both restricted maneuverability (ball-diamond-ball) on the tug and diamond shapes on both the towing vessel and the towed barges.
