What does "man overboard" protocol involve?

The correct answer outlines "man overboard" protocol as a series of steps to follow when a person falls overboard, including specific maneuvers and communication procedures. This structured approach is crucial for the safety of the individual in the water and the crew on the vessel.

When an incident of a person going overboard occurs, immediate action is required to increase the chances of rescue. The protocol typically includes tasks such as notifying the crew, making the necessary signaling calls, and executing pre-planned maneuvers to retrieve the person safely. This can involve turning the vessel around quickly, ensuring the person is visible in the water, and working as a cohesive team to execute the rescue.

The effectiveness of this protocol relies on the crew being familiar with the steps to take and the communication practices to follow, reflecting the importance of preparedness in emergency situations. The other options do not capture the proactive and detailed nature of "man overboard" procedures, which emphasize immediate action and coordination rather than casual alerts or routine operations.
