A short blast is a blast of about ___________ second(s) duration.

A short blast is defined as a signal that lasts for about 1 second. In maritime communication, particularly in the context of sound signals used by vessels, a short blast is typically utilized to convey specific information or intentions, such as indicating maneuvering actions or signaling to other vessels. The precise duration is important to ensure clarity in communication, especially in busy or hazardous environments. A blast of about 1 second is long enough to be distinguishable but short enough to maintain clarity and avoid confusion with other signals.
