Question 38 TV03 - Towing Vessels - Western Rivers

The Correct Answer is A ### Explanation for Option A (Hold course and speed) This scenario is governed by the Inland Rules of the Road (specifically Rule 9 on narrow channels and Rule 13 on overtaking). When a vessel (B, the overtaking vessel) signals its intention to overtake another vessel (A, the overtaken vessel) on the starboard side (one short blast), and vessel A agrees to the maneuver (by returning one short blast), vessel A must **maintain its course and speed**. Rule 13(d) states that the vessel being overtaken shall not impede the passage of the overtaking vessel. By holding course and speed, Vessel A ensures predictable movement, allowing Vessel B to safely execute the overtaking maneuver based on the agreement. ### Explanation for Incorrect Options **B) Slow your vessel until vessel "B" has passed:** This is incorrect. The overtaken vessel must maintain its speed unless slowing down is absolutely necessary to prevent a collision. Unnecessary deceleration disrupts the planned maneuver and could endanger the overtaking vessel, which has calculated its passage based on Vessel A's agreed-upon speed. **C) Alter course to the left:** This is incorrect. Altering course immediately after agreeing to the maneuver, especially toward the path of the overtaking vessel (which is passing on the starboard/right side), is highly dangerous and explicitly forbidden by the rules. The vessel being overtaken must maintain course. **D) Alter course to the left or right to give vessel "B" more sea room:** This is incorrect. While giving more sea room sounds helpful, the rules require the overtaken vessel to maintain a steady course. Unilateral course changes, even if intended to be helpful, introduce unpredictability and increase the risk of collision. The maneuver must be completed based on the agreed-upon signals, which mandate Vessel A holding course and speed.
