Question 20 RVR05 - Master of LT 100 GRT

The Correct Answer is B **Explanation for B (Correct Option):** Option B is correct based on the **Inland Navigational Rules (33 CFR Subchapter E)**, specifically Rule 9 (Narrow Channels). Rule 9(b) states: "An operator of a vessel intending to cross a narrow channel or fairway shall not impede the passage of a vessel which can safely navigate only within that channel or fairway." In this scenario: 1. The river on the Great Lakes System constitutes a narrow channel. 2. The vessel ascending the river is utilizing the narrow channel to navigate along its course. 3. Your vessel is crossing this narrow channel. Under Rule 9, the vessel operating *along* the channel (the ascending vessel) has the right of way over a vessel *crossing* the channel (your vessel). Therefore, the ascending vessel has the right of way. **Why other options are incorrect:** **A) You are required to propose the manner of passage.** This is incorrect. While normal passing situations (head-on, crossing, overtaking) require vessels to signal their intentions, in a narrow channel crossing scenario, the primary responsibility of the crossing vessel is simply *not to impede* the vessel using the channel. Proposing the manner of passage implies a negotiation of right-of-way that is predetermined by Rule 9. **C) Your vessel has the right of way, but you are directed not to impede the other vessel.** This is a self-contradictory statement and incorrect. If you are directed not to impede the other vessel (as mandated by Rule 9), then the other vessel effectively has the right of way (or priority of movement). Your vessel, as the crossing vessel, does *not* have the right of way. **D) The other vessel must hold as necessary to allow you to pass.** This is incorrect. This statement would only be true if your vessel had the right of way. Under Rule 9, the ascending vessel (which is constrained to the channel) is the privileged vessel, and the crossing vessel (you) must keep out of the way. The ascending vessel should maintain its course and speed, while you must take action to avoid impedance.
