What is the procedure for a "man overboard" drill?

The procedure for a "man overboard" drill emphasizes the importance of immediate action and clear communication to ensure the safety of the crew member who has fallen overboard. Alerting the crew is critical as it mobilizes additional personnel to assist in the rescue and ensures that everyone is aware of the emergency situation. Marking the position of the person in the water is vital for effectively planning the recovery efforts; it helps in identifying the exact location to return to for a rescue. Deploying rescue equipment, such as life rings or boats, is a necessary step to facilitate the retrieval of the individual, ensuring they can be brought back onboard safely.

This comprehensive approach covers all essential aspects of handling a man overboard scenario, allowing for a swift and organized response. In contrast, simply stopping all engines and waiting lacks proactive measures, while only calling for help does not address the immediate needs of the situation. Changing course immediately without marking the position could lead to confusion and a less efficient rescue operation. Thus, the chosen answer embodies the full scope of actions required for a safe and effective drill.
