Question 31 FCP01 - First Class Pilot

The Correct Answer is C **Explanation for Option C (Correct):** 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 vessel constrained by its tow must display certain lights or shapes. Specifically, if the length of the tow (measured from the stern of the towing vessel to the after end of the tow) **exceeds 200 meters**, the towing vessel must display, in addition to its masthead lights and sidelights, a **diamond shape** where it can best be seen. Therefore, the shape indicates a vessel with a tow exceeding 200 meters in length. **Explanation of Incorrect Options:** * **A) Is at anchor:** A vessel at anchor displays a **black ball** forward (or anchor lights at night). It does not display a diamond shape for anchoring. * **B) Is not under command:** A vessel not under command (NUC) displays **two black balls** in a vertical line (or two all-round red lights at night). It does not display a diamond shape for being NUC. * **D) Has a tow that is carrying hazardous cargo:** While vessels carrying hazardous cargo may have specific regional requirements or operational protocols, there is no requirement in COLREGs for a towing vessel to display a diamond shape specifically because the tow is carrying hazardous cargo. The diamond shape is solely dictated by the length of the tow (exceeding 200 meters).
