Question 10 MODU02 - Barge Supervisor

The Correct Answer is B **Explanation for B (Correct Answer):** The situation described is an overtaking situation where Vessel "A" is the overtaking vessel and Vessel "B" is the vessel being overtaken. According to both the International Regulations for Preventing Collisions at Sea (COLREGs) (Rule 13 - Overtaking) and the U.S. Inland Rules, the vessel being overtaken (Vessel "B") is the **Stand-on Vessel** relative to the overtaking vessel. Rule 13(d) states: "Any subsequent alteration of the bearing between the two vessels shall not make the overtaking vessel a crossing vessel within the meaning of these Rules or relieve her of the duty of keeping clear until she is finally past and clear." Rule 17 (Action by Stand-on Vessel) dictates the duties of the vessel that is required to keep her course and speed. Therefore, Vessel "B" should **hold her course and speed** while Vessel "A" (the Give-way Vessel) takes the necessary action to keep clear. **Explanation of Incorrect Options:** * **A) should slow down until vessel "A" has passed:** This is incorrect. The stand-on vessel (B) should maintain her course and speed. Slowing down could complicate the maneuver for the overtaking vessel (A) and is contrary to the required action under Rule 17. * **C) may steer various courses and vessel "A" must keep clear:** This is incorrect. While Vessel "A" must keep clear, Vessel "B"'s primary duty is to keep her course and speed. Varying course would make her actions unpredictable and violate the fundamental principle of maintaining the integrity of the stand-on/give-way relationship. (Note: Rule 17 does allow the stand-on vessel to act if collision cannot be avoided by the give-way vessel's action alone, but the initial duty is to maintain course and speed). * **D) should change course to the right:** This is incorrect. Vessel "B" is the stand-on vessel and must maintain her course and speed. Changing course (left or right) would violate her primary duty and transfer the burden of avoiding collision, which rests solely with the give-way vessel (A).
