Question 10

The Correct Answer is B **Explanation for Option B (Correct Answer):** This scenario is governed by the International Regulations for Preventing Collisions at Sea (COLREGS), specifically Rule 13 (Overtaking) and Rule 17 (Action by Stand-on Vessel). 1. **Rule 13 (Overtaking):** Establishes that the vessel being overtaken (Vessel B) is the **stand-on vessel** and the vessel overtaking (Vessel A) is the **give-way vessel**. Vessel A is required to keep clear of Vessel B. 2. **Rule 17 (Action by Stand-on Vessel):** Generally requires the stand-on vessel to **keep her course and speed** while the give-way vessel executes the necessary maneuvers to pass safely. This predictability is crucial for collision avoidance. Therefore, Vessel B (the stand-on vessel) is required to maintain its course and speed. --- **Explanation for Incorrect Options:** * **A) should slow down until vessel "A" has passed:** This is incorrect. Changing speed (slowing down) would violate Rule 17, making the intentions of Vessel B unpredictable and potentially complicating Vessel A's safe passing maneuver. * **C) may steer various courses and vessel "A" must keep clear:** This is incorrect. While Vessel A must keep clear, Vessel B (the stand-on vessel) is obligated by Rule 17 to maintain a predictable course and speed. Varying courses would be highly dangerous and violate the fundamental principle of the stand-on/give-way relationship. * **D) should change course to the right:** This is incorrect. Changing course would violate Rule 17. The stand-on vessel should only maneuver if collision cannot be avoided by the action of the give-way vessel alone (Rule 17(a)(ii) and (b)), which is not implied in a standard overtaking situation. Furthermore, arbitrarily changing course adds unpredictability.
