Rules of the Road · Towing & Pushing
During daylight hours, a vessel towing another vessel where the length of tow exceeds 200 meters shall display:
- AA black diamond shape
- BA black cylinder
- CA black diamond shape forward and one on the towed vessel✓ Correct
- DA black cone, point downward
Explanation
Rule 24(a)(iv) requires a diamond shape where it can best be seen on the towing vessel, and Rule 24(e)(ii) requires a diamond shape on the towed vessel, when the length of tow exceeds 200 meters. This alerts other vessels to the extended hazard.
Authority: 72 COLREGS Rule 24(a)(iv) and Rule 24(e)(ii)
