Which class of vessel is NOT required to show the RAM lights and shapes but may still be impeded?
- AA vessel engaged in dredging
- BA vessel constrained by her draft
- CA vessel engaged in minesweeping
- DA vessel towing a tow over 200 meters✓ Correct
Explanation
A vessel towing a long tow is not a RAM vessel and does not show red-white-red lights; it shows the towing lights specified in Rule 24. Rule 27 covers NUC, RAM, dredging/underwater operations, and minesweeping — not vessels merely engaged in towing.
