If a vessel is sending a distress call, how many times should the word 'MAYDAY' be repeated?

When a vessel sends a distress call, the word "MAYDAY" should be repeated three times. This repetition serves a crucial purpose in maritime communication, as it helps to ensure that the distress signal is clearly understood and recognized by all listeners. In emergencies where time is critical, the repetition reinforces the seriousness of the situation, allowing other vessels and stations to prioritize their response.

The protocol of repeating "MAYDAY" in this manner is established by international maritime communication guidelines, which help standardize communication practices and reduce the chance of misunderstandings. Effective communication is vital for safety at sea, as it enables rescuers to respond promptly and accurately to the distress call.
