If you hear 5 short blasts from another vessel's horn, what is being signaled?

Hearing five short blasts from another vessel's horn is a significant signal indicating that a dangerous situation exists. This alert is used in the maritime community as a warning that another vessel is either unsure of your intentions or is signaling to you that they believe a perilous situation is developing. Such a horn signal is recognized internationally and is critical in preventing collisions or accidents at sea.

In maritime communication, specific horn signals serve to convey crucial information quickly when visibility is limited or when vessels are in close proximity. While other signals pertain to safe maneuvers or acknowledgments, the five short blasts are specifically reserved for cautioning of danger. Understanding these horn signals is essential for maintaining safety on the water and being able to react appropriately in such situations.
