Question 113 Rules of the Road

The correct answer is C) The vessel moving downstream with a following current. The reasoning is based on the Inland Navigation Rules, which state that in a narrow channel, the vessel with the current (moving downstream) has the right-of-way over a vessel moving against the current (upstream). This is because the downstream vessel has less ability to maneuver and stop in the narrow channel compared to the upstream vessel. The other options are incorrect because the order of the whistle signal (A) and the vessel's position in the channel (D) do not take precedence over the downstream vessel's right-of-way. The upstream vessel (B) must take early and substantial action to avoid a collision with the downstream vessel.
