Question 10 GLI07 - OUPV

The Correct Answer is B **Explanation for B (Correct Answer):** The scenario described—Vessel "A" (the overtaking vessel) passing Vessel "B" (the vessel being overtaken)—is governed by Rule 13 (Overtaking) of the International Regulations for Preventing Collisions at Sea (COLREGs) and the corresponding Inland Rules. Rule 13(d) states: "Any subsequent alteration of the bearing between the two vessels shall not make the one an overtaking vessel within the meaning of these Rules or relieve the overtaking vessel of the duty of keeping clear until she is finally past and clear." Critically, the general responsibility of the vessel being overtaken is derived from the responsibility of the overtaking vessel (Vessel A) to "keep clear" (Rule 13(b)) and the general responsibilities of the stand-on vessel (Vessel B) in a crossing situation (Rule 17), which applies analogously here: **The vessel being overtaken (Vessel B) must maintain her course and speed to allow the overtaking vessel (Vessel A) to execute the maneuver safely and predictably.** **Explanation of Incorrect Options:** * **A) should slow down until vessel "A" has passed:** This is incorrect. Changing speed (slowing down) would introduce unpredictability and complexity into the maneuver, potentially forcing the overtaking vessel (A) to make last-minute adjustments, thereby violating Rule 8 (Action to avoid collision) which requires positive and ample action. Vessel B must maintain a predictable state. * **C) may steer various courses and vessel "A" must keep clear:** This is incorrect. While Vessel A must indeed keep clear, Vessel B is acting as the stand-on vessel in this maneuver and must maintain a predictable course and speed. Changing course would violate Rule 17(a)(i), which requires the stand-on vessel to keep her course and speed, and would create a dangerous situation. * **D) should change course to the right:** This is incorrect for the same reason as option C. Changing course (even to the right) makes the vessel's movement unpredictable and complicates the overtaking vessel's duty to keep clear, thus violating the fundamental principle that the vessel being overtaken should hold her course and speed.
