How long does a prolonged blast last?

A prolonged blast typically lasts between 4 to 6 seconds, which is significant for communication and signaling on the water. This duration is important for ensuring that the sound of the blast can be clearly heard and understood by others nearby, especially in situations where visibility may be reduced or where boats need to maneuver safely in proximity to each other.

Understanding the standard duration for a prolonged blast is crucial for boat operators as it adheres to established maritime signaling conventions. This allows for effective communication of intentions, particularly in crowded waterways or when approaching navigation hazards. The clarity and length of the blast help convey urgency or warning, ensuring that other boaters can react appropriately.
