Question 34 UFV02 - Mate - Uninspected Fishing Vessels

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 signal is prescribed by both the International Regulations for Preventing Collisions at Sea (COLREGs/72) and the Inland Rules (Rule 24, Towing and Pushing). A towing vessel and its tow, when the length of the tow measured from the stern of the towing vessel to the after end of the tow exceeds 200 meters, must exhibit this day signal (a diamond shape). **Why other options are incorrect:** * **B) Has a tow that is carrying hazardous cargo:** There is no specific day shape defined by COLREGs/Inland Rules solely for a vessel having a tow carrying hazardous cargo. * **C) Is at anchor:** A vessel at anchor displays a black ball day shape (Rule 30). * **D) Is not under command:** A vessel not under command displays two black balls in a vertical line (Rule 27).
