Question 20 TV03 - Towing Vessels - Western Rivers

The Correct Answer is B **2. Explanation of why option B is correct:** The scenario described falls under the **Western Rivers Rules** (specifically, 33 CFR § 89.25 - Crossing of Rivers on Great Lakes System), which are applied to the Great Lakes System when vessels are crossing rivers. Rule 33 CFR § 89.25 states: "When a power-driven vessel is crossing a river, if the crossing vessel **can do so without interfering with the safe movement of a vessel ascending or descending the river**, the crossing vessel shall do so." This rule essentially establishes that vessels ascending (going upstream) or descending (going downstream) the river have the right of way over vessels merely crossing the river. Since the other vessel is ascending the river, it is the favored vessel, and the crossing vessel (your vessel) must not impede its safe passage. Therefore, the vessel ascending the river has the right of way. **3. Explanation of why the other options are incorrect:** * **A) You are required to propose the manner of passage.** This is incorrect. While collision regulations often require communication, the primary requirement here (under the special rule for crossing rivers on the Great Lakes System) is that the crossing vessel (you) must keep clear and not impede the ascending vessel. The ascending vessel (the one with the right of way) is expected to maintain its course and speed. * **C) Your vessel has the right of way, but you are directed not to impede the other vessel.** This is incorrect. Your vessel (the crossing vessel) does **not** have the right of way. The rule specifically subordinates the crossing vessel to traffic moving along the river (ascending or descending). * **D) The other vessel must hold as necessary to allow you to pass.** This is incorrect. Since the other vessel is ascending the river and has the right of way according to the rules (33 CFR § 89.25), it is the crossing vessel (you) that must hold, slow, or stop as necessary to allow the favored vessel to pass safely and without interference.
