What does one short blast indicate when maneuvering?

One short blast indicates a specific maneuvering intention of a vessel, particularly in situations where communication of intentions is crucial for safety. When a vessel's operator uses one short blast, it signifies that the vessel is turning to starboard. This is part of the sound signal regulations as outlined in maritime navigation rules, which help ensure that vessels are aware of each other's movements, thereby enhancing safety and reducing the risk of collisions.

In maritime practice, the signaling of maneuvers through sound is critical, especially in conditions of reduced visibility or in close quarters. By using one short blast, a vessel clearly communicates its intention to pivote right (starboard), allowing other vessels in the vicinity to understand and react appropriately to the maneuver.
