BOTH INTERNATIONAL & INLAND Which vessel is indicated by the day signal shown in illustration D022RR?

Correct Answer: Option B — A tug with a tow exceeding 200 meters which limits her ability to maneuver

Annex I and Rule 24(c) specify that a vessel engaged in towing, where the length of the tow exceeds 200 meters, must exhibit a diamond shape where it can best be seen. This day signal alerts other mariners to the extended length and restricted maneuverability of the towing vessel.
