How long does a short blast last?

A short blast typically lasts about one second. This timing is significant because it serves as a standardized signaling practice on the water, especially to indicate intentions such as to alert others of your presence, to signify a turn, or to request passage. Keeping the blast around one second provides a clear and recognizable signal without causing confusion among other boaters.

In maritime communication, understanding these timing conventions is critical for safety. A blast that is too short might not be noticed, while one that is too long could be mistaken for a different type of signal. Therefore, knowing that a short blast lasts about one second ensures that the message conveyed is both effective and easily interpretable.
