BOTH INTERNATIONAL & INLAND Which of the day-shapes shown in illustration D016RR below would you show on the after end of an inconspicuous partially submerged vessel or object being towed less than 200 meters in length?

Correct Answer: Option B — B

Under COLREG Rule 24 and Inland Rules, a towed vessel or object exceeding 200 meters must exhibit a diamond day-shape where it can best be seen. For tows under 200 meters, this shape is not required on the towed object, but a diamond shape represents the over-200-meter requirement.
