Question 38 RVR01 - Master of Unlimited Tonnage

The Correct Answer is A ### Why Option A ("Hold course and speed") is correct: This scenario involves overtaking under Inland Rules, where vessel "A" is the vessel being overtaken and vessel "B" is the overtaking vessel. 1. **Rule 13 (Overtaking):** The rule states that the vessel being overtaken (vessel "A") must maintain her course and speed. She is considered the stand-on vessel relative to the immediate action of the overtaking maneuver. 2. **Signal Exchange (Inland Rules):** Under Inland Rules, the overtaking vessel (B) initiates the signal (one short blast means "I intend to overtake you on your starboard side"). The vessel being overtaken (A) must agree to the maneuver by answering with the same signal (one short blast). 3. **Vessel A's Duty:** Once the signal is exchanged and agreement is reached, vessel "A" must continue to hold her course and speed to allow the maneuvering vessel ("B") to safely execute the pass. ### Why the other options are incorrect: * **B) Slow your vessel until vessel "B" has passed:** This is incorrect. Altering speed (slowing down) changes the expected maneuver time and distance, potentially confusing the overtaking vessel and increasing the risk of collision. Vessel "A" must hold speed. * **C) Alter course to the left:** This is incorrect. Altering course is forbidden for the stand-on vessel (A) under this rule, as it would interfere with the safe execution of the maneuver by vessel "B". Furthermore, altering course to the left would potentially put vessel "A" directly into the path of vessel "B" which is passing on the starboard side. * **D) Alter course to the left or right to give vessel "B" more sea room:** This is incorrect. While the intent might seem helpful, the vessel being overtaken (A) must maintain her predictable course and speed. Any alteration of course (left or right) makes the maneuver unpredictable and is a violation of the rule for the vessel being overtaken.
