Morale, Welfare, and Recreation (MWR) Boater Safety Practice Exam

If ever in doubt as to the intentions of another vessel, what should you do?

1. Use the boat's radar

2. Use a whistle or shout

3. Change your course immediately

4. Anchor and wait

The correct answer is: Use a whistle or shout

When uncertain about the intentions of another vessel, using a whistle or shouting serves as an effective means of communication to clarify intentions and avoid potential confusion or collisions on the water. Sound signals, like a whistle, can alert the other vessel that you are present and can prompt them to communicate their intentions as well. Using sound signals is part of the standard maritime protocol for communication, especially in situations where visual signals may not be clear due to distance, weather conditions, or other factors. Engaging another vessel through sound allows for immediate feedback, which is crucial in ensuring safety on the water. The other methods may not provide the same immediacy or clarity in communication. Relying on radar may not help if the other vessel is not equipped or if radar visibility is limited. Changing your course immediately could create unpredictability, potentially leading to confusion or a collision. Anchoring and waiting could leave you vulnerable and might not be practical in dynamic situations where immediate action is required to ensure safety. Therefore, utilizing a whistle or shouting to seek clarification is a proactive and accepted practice in boating safety.
