Question 34 FCP01 - First Class Pilot

The Correct Answer is A. A tugboat displaying the shape shown in illustration D010RR (a black diamond shape) is indicating that it has a tow that exceeds 200 meters in length. This requirement is mandated by the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 24(a)(ii) and Annex I, which requires a vessel or composite unit when towing and the length of the tow exceeds 200 meters, to exhibit a diamond shape where it can best be seen. **Why other options are incorrect:** * **B) Has a tow that is carrying hazardous cargo:** There is no specific shape signal (like the diamond) prescribed by COLREGs for a tugboat simply based on its tow carrying hazardous cargo. * **C) Is at anchor:** A vessel at anchor displays a black ball forward (and potentially a second ball aft for vessels over 50 meters), not a diamond shape. * **D) Is not under command:** A vessel not under command displays two black balls in a vertical line, not a diamond shape.
