Question 10 GLI03 - Master-LT 500-1600 GRT

The Correct Answer is B **Explanation for B (Correct Answer):** The scenario described—Vessel "A" (the overtaking vessel) overtaking Vessel "B" (the vessel being overtaken)—is governed by Rule 13 (Overtaking) of the International Regulations for Preventing Collisions at Sea (COLREGs), which applies equally to both International and Inland waters (as the specific Inland Rules concerning overtaking mirror or defer to the COLREGs framework). 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."** Furthermore, the fundamental principle for the vessel being overtaken (Vessel "B") is established by Rule 17 (Action by Stand-on Vessel) when read in conjunction with Rule 13. Vessel "B" is the **"stand-on vessel"** relative to Vessel "A" (the "give-way vessel") in this overtaking situation. The stand-on vessel's primary duty under Rule 17(a)(i) is to **"keep her course and speed."** Therefore, Vessel "B" should hold her course and speed. **Explanation for Incorrect Options:** * **A) should slow down until vessel "A" has passed:** This is incorrect. Changing speed (slowing down) violates Rule 17(a)(i). The stand-on vessel must maintain predictable movement (course and speed) unless collision cannot be avoided by the give-way vessel's action alone (Rule 17(b)). * **C) may steer various courses and vessel "A" must keep clear:** This is incorrect. Vessel "B" (the stand-on vessel) must maintain a steady course, not steer "various courses." Maintaining course is essential for Vessel "A" to predict Vessel "B"'s movement and execute the overtaking maneuver safely. * **D) should change course to the right:** This is incorrect. Changing course violates the duty of the stand-on vessel to maintain its course and speed. While changing course may be permissible later under Rule 17(b), the initial requirement is to maintain course and speed.
