Diagram for question 378
AI Explanation
The correct answer is C) Both vessels should sound two short blasts. This is correct because under the Inland Navigation Rules, when two power-driven vessels are meeting in a narrow channel, both vessels should sound two short blasts to indicate that they intend to pass port-to-port. This is the standard whistle signal for a meeting situation in a narrow channel, where a change of course and/or speed may be necessary to safely pass. The other answer choices are incorrect because option A would be the wrong signal, option B would not be sufficient, and option D would be incorrect as some whistle signal is required in this meeting situation.
