Question 40 RVR02 - Master of LT 500-1600 GRT

The Correct Answer is D 1. **Explanation of Option D (Correct Answer):** Option D, "The vessel moving downstream with a following current," is correct based on the Inland Navigation Rules (33 CFR Subchapter E), specifically Rule 9(a)(ii) regarding narrow channels, and Rule 14(d) regarding head-on situations on the Western Rivers. Rule 14(d) states that in a narrow channel or river when a power-driven vessel proceeding downstream with a following current meets a power-driven vessel proceeding upstream, the vessel proceeding **downstream** (with the current) shall have the right of way and must propose the manner of passage. This is because a vessel moving with a following current is often more difficult to maneuver and stop, giving the priority to the vessel that is less agile. 2. **Explanation of Incorrect Options:** * **A) The vessel located more towards the channel centerline:** Vessel position relative to the centerline is dictated by the rules (staying to the starboard side of the channel when safe and practicable), but it does not determine the right-of-way priority in a meeting situation on the Western Rivers; current is the determining factor. * **B) The vessel sounding the first whistle signal:** Whistle signals are used to propose or acknowledge a passing agreement, not to establish the initial right-of-way. The right-of-way is pre-assigned by the rules (Rule 14(d)) based on the direction of travel relative to the current. * **C) The vessel moving upstream against the current:** This vessel is the "burdened" vessel (the one without the right of way) in this scenario according to Rule 14(d). The vessel moving upstream is usually easier to control and stop against the current, so it must hold station or maneuver as necessary to permit the downstream vessel to pass.
