What does the signal "one short blast" generally indicate?

The signal "one short blast" is utilized in maritime communication to indicate a specific maneuver, particularly in situations where a vessel is about to take action related to its navigation. In most contexts, this signal is understood to mean that a vessel is approaching from the starboard side or is signaling an intention to pass another vessel on that side.

This signal is part of a standardized system of sound signals that help ensure safe navigation, especially in situations where visibility may be limited.
