Question 34

The Correct Answer is A. **Explanation for A (Correct Option):** The illustration D010RR depicts a vessel displaying a **diamond shape**. According to the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 24 (Towing and Pushing), a power-driven vessel when towing, whose tow exceeds 200 meters in length, is required to display specific day shapes. The required day shape is a **diamond shape** where it can best be seen. Therefore, the presence of the diamond shape indicates the tugboat has a tow that exceeds 200 meters in length. **Explanation for Incorrect Options:** **B) Has a tow that is carrying hazardous cargo:** There is no specific required day shape (like a diamond) solely for a vessel towing hazardous cargo under COLREGs. **C) Is at anchor:** A vessel at anchor displays a **ball** day shape forward (and a second ball aft if over 50 meters in length), not a diamond shape. **D) Is not under command:** A vessel not under command (NUC) displays **two balls** in a vertical line where they can best be seen, not a diamond shape.
