In a man overboard situation, waving arms above the head is a universally recognized signal indicating distress and the need for immediate assistance. This action draws attention to the person who has fallen overboard and communicates urgency to nearby vessels and crew members. It’s crucial for others to observe this signal quickly to initiate a rescue.

While continuous horn blasts are often associated with signaling a warning or danger, they do not specifically indicate a man overboard scenario. Similarly, three short blasts of a horn typically signify a specific maneuver or a request for assistance, but they do not directly communicate a man overboard situation. Flashing emergency lights are also used to signal distress, but they may not be visibly noticeable from a distance, especially during the day. Therefore, the clear and immediate action of waving arms above the head effectively alerts others to the emergency and is the most appropriate response in this situation.
