Question 10 ONC07 - OUPV-Near Coastal

The Correct Answer is B **Explanation for Option B (Correct Answer):** This scenario is governed by the International Regulations for Preventing Collisions at Sea (COLREGs), specifically Rule 13 (Overtaking) and Rule 17 (Action by Stand-on Vessel). 1. **Rule 13 (Overtaking)** states that any vessel overtaking another shall keep out of the way of the vessel being overtaken. Vessel "A" is the overtaking vessel (give-way vessel). 2. **Rule 17 (Action by Stand-on Vessel)** states that where one vessel is required to keep out of the way (the give-way vessel, Vessel "A"), the other vessel (the stand-on vessel, Vessel "B") **shall keep her course and speed**. Therefore, Vessel "B" (the vessel being overtaken) is the stand-on vessel and must hold her course and speed to allow Vessel "A" to maneuver safely and pass. **Explanation of Incorrect Options:** * **A) should slow down until vessel "A" has passed:** This is incorrect. The stand-on vessel (Vessel "B") must maintain her course and speed to ensure the give-way vessel (Vessel "A") can predict her movement and execute the passing maneuver safely, as required by Rule 17. Slowing down unexpectedly would violate this rule and could cause a dangerous situation. * **C) may steer various courses and vessel "A" must keep clear:** This is incorrect. Vessel "B" is obligated to maintain a predictable course and speed (Rule 17). Steering various courses would make it impossible for Vessel "A" to safely assess the passing situation and keep clear, defeating the purpose of the stand-on/give-way rules. * **D) should change course to the right:** This is incorrect. Changing course is an action reserved for the give-way vessel (Vessel "A"). Vessel "B" must maintain her existing course and speed. An unexpected course change by the stand-on vessel is only permitted under Rule 17(b) if collision cannot be avoided by the action of the give-way vessel alone, which is not the primary requirement in a standard overtaking scenario.
