Question 10 FCP01 - First Class Pilot

The Correct Answer is B **Why option B ("should hold her course and speed") is correct:** The scenario described (Vessel "A" overtaking Vessel "B") is governed by Rule 13 (Overtaking) and Rule 17 (Action by Stand-on Vessel) of the International Regulations for Preventing Collisions at Sea (COLREGs), which apply to both International (COLREGs) and Inland waters (US Inland Rules mirror COLREGs closely in this context). 1. **Rule 13 identifies the roles:** Vessel "A" is the Overtaking vessel (Give-way vessel), and Vessel "B" is the vessel being overtaken (Stand-on vessel). 2. **Rule 17 governs the Stand-on Vessel's action:** Rule 17(a)(i) explicitly states that where one of two vessels is required to keep out of the way, the other vessel shall **keep her course and speed**. Vessel "B" is the stand-on vessel and must maintain predictability for the give-way vessel ("A") to execute a safe passing maneuver. **Why the other options are incorrect:** * **A) should slow down until vessel "A" has passed:** This is incorrect because the stand-on vessel (B) is required to hold her speed to maintain predictability. Slowing down could complicate the overtaking maneuver for vessel A and potentially cause a collision. * **C) may steer various courses and vessel "A" must keep clear:** This is incorrect. The stand-on vessel must maintain a constant course and speed (Rule 17(a)(i)). Changing course unpredictably would violate the basic principles of collision avoidance and significantly increase the risk of collision. While vessel A must keep clear, vessel B must also adhere to her duty as the stand-on vessel. * **D) should change course to the right:** This is incorrect. Rule 17 requires the vessel being overtaken (stand-on vessel) to maintain course and speed. Changing course (left or right) is specifically prohibited unless a collision cannot be avoided by the action of the give-way vessel alone (Rule 17(b) – the "last minute" action exception), which is not indicated here.
