90% to pass

INLAND ONLY While underway and in sight of another vessel a mile ahead you put your engines on astern propulsion. Which statement concerning whistle signals is TRUE?

A You need not sound any whistle signals.

B You must sound whistle signals only if the vessels are meeting.

C You must sound three short blasts on the whistle.

D You must sound one blast if backing to starboard.

AI Explanation

The correct answer is A) You need not sound any whistle signals. According to the Inland Navigation Rules, specifically Rule 34, whistle signals are only required when vessels are in a meeting, crossing, or overtaking situation. Since the question states that the vessels are in sight of each other but not in a meeting, crossing, or overtaking situation, no whistle signals are required. The other options are incorrect because they either require unnecessary whistle signals or specify the wrong type of whistle signal for the given scenario.
