One long blast followed by two short blasts is a sound signal used in maritime navigation, indicating a vessel's intention to maneuver or that it is approaching a junction in a narrow channel. Specifically, it typically means "I intend to leave the berth" or "I am departing." This signal is part of the International Regulations for Preventing Collisions at Sea (COLREGs) and helps ensure safe communication between vessels.
