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

What does three short blasts typically indicate in boating communication?

1. I intend to pass starboard

2. I intend to leave you on my PORT side

3. I am reversing my engine

4. I am stopping your vessel

The correct answer is: I intend to leave you on my PORT side

Three short blasts in boating communication is a signal used to indicate that a vessel is reversing its engine. This communication is part of the International Regulations for Preventing Collisions at Sea (COLREGs), which establish standardized signals to promote safety on the water. When a vessel sounds three short blasts, it informs other mariners that it is moving backwards, which is crucial for ensuring that vessels are aware of its actions and can maneuver accordingly to avoid collisions. This signal is particularly important in busy or narrow waterways where understanding the intentions of nearby vessels can prevent accidents. Knowing this helps reinforces the understanding of navigation rules and safe boating practices, making it essential for all boaters to recognize and respond appropriately to such signals.
