Question 20 RVR02 - Master of LT 500-1600 GRT

The Correct Answer is B **Explanation of B (The vessel ascending the river has the right of way):** This scenario is governed by the U.S. Inland Navigation Rules, specifically Rule 9 (Narrow Channels). The Great Lakes System often involves designated narrow channels or rivers where special rules apply to manage traffic flow. In situations where vessels are navigating narrow channels or rivers: 1. **Rule 9(b) (Great Lakes Exception):** A vessel ascending or descending the Great Lakes System, the St. Lawrence River, or other specified rivers (such as the Mississippi River) generally has the right-of-way over a vessel crossing the river. This prioritization ensures the unimpeded movement of primary traffic within the designated channel, which often has depth or current constraints. 2. **Ascending/Descending Traffic Priority:** The power-driven vessel traveling along the channel (ascending the river) is the privileged vessel. 3. **Crossing Vessel Duty:** Your vessel (crossing the river) is the burdened vessel and must keep out of the way of the ascending traffic. Therefore, the vessel ascending the river has the right of way. **Why the other options are incorrect:** * **A) You are required to propose the manner of passage.** This is incorrect. While collision avoidance requires communication, the primary responsibility (the duty to keep clear) is placed on the crossing vessel (you). Proposing the manner of passage does not negate your requirement to keep out of the way of the privileged vessel. The burden is on you to not impede. * **C) Your vessel has the right of way, but you are directed not to impede the other vessel.** This is incorrect because your vessel is crossing the channel, making it the burdened vessel under Rule 9. You do **not** have the right of way. The directive to "not impede" is correct, but the premise that you have the right of way is false. * **D) The other vessel must hold as necessary to allow you to pass.** This is incorrect. Under Rule 9, the vessel proceeding along the narrow channel (the ascending vessel) is the privileged vessel and has the right of way. The crossing vessel (your vessel) must hold, slow down, or take other action necessary to allow the ascending vessel to pass safely.
