What duration does a SHORT BLAST in whistle signals signify?

A SHORT BLAST in whistle signals is defined as a sound that lasts for approximately 1 second. This duration is standardized in maritime communication to ensure clarity and consistency between vessels on the water. The use of a short blast typically indicates a maneuver or intention, such as signaling an intention to pass, and is essential for maintaining safety and coordination in busy waterways.

Recognizing the proper duration for signals is crucial for effective communication at sea, helping to prevent misunderstandings that could lead to accidents or navigation errors. Therefore, understanding the significance of signal duration in maritime practices is important for anyone operating a vessel.
