Question 10

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 both the International Regulations for Preventing Collisions at Sea (COLREGs) and the Inland Rules. Rule 13(a) states that any vessel approaching another from a direction more than $22.5$ degrees abaft her beam is deemed to be an overtaking vessel and must keep clear. Rule 13(d) specifically states: **"Notwithstanding the sections of these Rules regarding right-of-way, the vessel being overtaken shall keep her course and speed."** Therefore, Vessel "B," the vessel being overtaken, is required by the rules to maintain her course and speed to allow Vessel "A" to maneuver safely around her and complete the overtaking maneuver. **Explanation of Incorrect Options:** * **A) should slow down until vessel "A" has passed:** This is incorrect. Changing speed (slowing down) violates Rule 13(d), which mandates that the vessel being overtaken must keep her speed. Changing speed could confuse the overtaking vessel or make the maneuver unsafe. * **C) may steer various courses and vessel "A" must keep clear:** This is incorrect. Changing course (steering various courses) violates Rule 13(d), which mandates that the vessel being overtaken must keep her course. Vessel "A" must keep clear, but Vessel "B" still has the responsibility to maintain a predictable path. * **D) should change course to the right:** This is incorrect. Vessel "B" is required to keep her course. Any change in course, including turning right, is a violation of the rule requiring the vessel being overtaken to hold a steady course.
