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" in this case) is the **stand-on vessel**, and the vessel doing the overtaking (Vessel "A") is the **give-way vessel**. Vessel "A" must keep clear of Vessel "B." 2. **Rule 17 (Action by Stand-on Vessel):** Requires the stand-on vessel (Vessel "B") to **keep her course and speed**. This predictability is crucial for the give-way vessel (Vessel "A") to effectively take early and substantial action to pass safely. Therefore, Vessel "B" should hold her course and speed. --- **Why the other options are incorrect:** * **A) should slow down until vessel "A" has passed:** This is incorrect because Vessel "B" is the stand-on vessel and must maintain her speed to ensure predictability for Vessel "A." Slowing down would violate Rule 17(a)(i). * **C) may steer various courses and vessel "A" must keep clear:** This is incorrect. The stand-on vessel (B) is required to maintain a predictable course and speed. Varying her course would confuse the give-way vessel (A) and dramatically increase the risk of collision, directly violating Rule 17(a)(i). * **D) should change course to the right:** This is incorrect. Vessel "B" is the stand-on vessel and should not normally change course. A change of course to the right would only be required under Rule 17(b) if a collision cannot be avoided by the action of the give-way vessel alone, which is not the standard procedure for an initial overtaking situation.
