How long is a short blast in signaling?

A short blast in signaling is defined as lasting about 1 second. This standard duration is used in maritime communication to convey messages between vessels or between a vessel and a shore station. Short blasts are typically sounded with a horn or whistle and play a crucial role in ensuring safe navigation, particularly in visibility-restricted conditions such as fog.

Understanding this duration helps boaters effectively communicate their actions or intentions to others on the water, promoting safety and preventing collisions. For example, a short blast is often used to indicate a maneuver, like passing or signaling an intention to overtake another vessel. By adhering to this recognized timing, boaters can ensure their signals are understood and followed correctly by others nearby.
