Question 14 RVR05 - Master of LT 100 GRT

The Correct Answer is B **Explanation for Option B (Correct Answer):** The situation described is a crossing situation under the International Regulations for Preventing Collisions at Sea (COLREGs), specifically Rule 15 (Crossing Situation). Rule 15 applies whenever two power-driven vessels are crossing so as to involve risk of collision. The vessel which has the other on her own starboard side must keep out of the way (the give-way vessel). Since the other vessel is approaching your vessel on your starboard beam, your vessel is the give-way vessel and must take early and substantial action to keep clear. The fact that your vessel is stopped and "making no way" (zero speed through the water) does not change its status as a power-driven vessel, nor does it automatically grant it privileged status. **Explanation for Incorrect Options:** **A) You should be showing the lights or shapes for a vessel not under command.** Incorrect. A vessel "not under command" (NUC) is unable to maneuver as required by the Rules due to some exceptional circumstance (e.g., engine failure, heavy weather damage). The prompt explicitly states your vessel is "not in any way disabled." Since the vessel is fully functional, it must comply with standard crossing rules and does not qualify as NUC (Rule 3(g)). **C) You should be showing the lights or shapes for a vessel restricted in her ability to maneuver.** Incorrect. A vessel "restricted in her ability to maneuver" (RAM) is a vessel whose ability to maneuver is limited by the nature of her work (e.g., dredging, laying cable, servicing navigation marks). Stopping temporarily and making no way does not constitute being RAM. Your vessel is a regular power-driven vessel (Rule 3(h)). **D) The other vessel must give-way since your vessel is stopped.** Incorrect. There is no provision in the COLREGs that grants priority status solely because a power-driven vessel is stopped and making no way. The order of priority and the responsibilities in a crossing situation are determined by the relative positions (Rule 15) and the type of vessel (Rule 18). Your vessel retains its status as a power-driven vessel, and since the other vessel is on your starboard side, you are the give-way vessel.
