Question 5 RVR01 - Master of Unlimited Tonnage

The Correct Answer is A. ### Explanation for Option A (Correct) Option A ("The vessel downbound with a following current") is correct based on the specific rules governing navigation on inland waters subject to current, particularly the Western Rivers and the Great Lakes (where specific localized rules apply regarding passing). Rule 90.04(a) of the Western Rivers Pilot Rules (which apply broadly to the Great Lakes and waters specified by the Secretary regarding currents) states: > "The vessel proceeding **downbound** with a following current shall have the right-of-way over an **upbound** vessel, shall propose the manner of passage, and shall sound the first passing signal." The underlying logic is that a vessel moving with a following current (downbound) has less maneuverability, requires more stopping distance, and is therefore given the prerogative to initiate the passing arrangement to ensure the safety of both vessels. ### Explanation of Incorrect Options **B) Either vessel:** This is incorrect. While in many open-water passing situations governed by the standard Inland Rules (33 CFR 83.34), the vessel required to initiate the signal depends on the relative positions (head-on, crossing, overtaking), on the Western Rivers and waters with a defined current, the downbound vessel with the following current is explicitly mandated to sound the first signal and propose the manner of passage. **C) The vessel going upstream stemming the current:** This is incorrect. The vessel stemming the current (upbound) has greater maneuverability and control (easier to stop or slow down). It is the vessel that must yield to the proposal made by the downbound vessel (Option A). **D) The vessel that is towing regardless of the current:** This is incorrect. While towing vessels often have specific rights or restrictions, the critical factor in this specific rule regarding meeting in a current is the direction of the current relative to the vessel's movement (downbound/upbound), not whether the vessel is towing. The downbound vessel with the current initiates the signal, regardless of whether it is a tow or a single vessel.
