What does two short horn blasts signify?

Two short horn blasts signify the intention to pass another vessel on the starboard side. This signal is an important aspect of navigational communication between boats, designed to enhance safety on the water. When a vessel sounds two short horn blasts, it is informing nearby boats of its maneuver and indicating that it will keep them on their port side as it passes.

This action is standard practice in maritime navigation to ensure other vessels are aware of each other's movements, helping prevent potential collisions and allowing for smoother transit in busy waterways. Clear communication through sound signals, such as horn blasts, is crucial, especially in situations where visibility may be limited or when vessels are in close quarters.
