INTERNATIONAL ONLY Vessel "A" is overtaking vessel "B" on open waters and will pass without changing course. Which action should vessel "A" take?

Correct Answer: Option D — Not sound any whistle signals

Rule 34(a) applies only when vessels are in sight of one another and are taking action to alter course. If an overtaking vessel passes without changing course, no whistle signal is required under the International Rules, as there is no rudder action to communicate to the vessel being overtaken.
