What is the immediate action for a Man Overboard (MOB) situation?

In a Man Overboard (MOB) situation, the first step is to initiate a MOB drill. This drill is specifically designed to ensure that the crew responds quickly and efficiently to the emergency at hand. By following established protocols, the crew can assess the situation, communicate effectively, and organize a search and rescue effort, which may include maneuvering the vessel to recover the person overboard.

Initiating the MOB drill involves providing clear instructions to the crew, notifying the bridge and other key personnel, and preparing necessary equipment, such as life rings or rescue devices. This organized approach is crucial for maximizing the chances of a successful recovery.

The other options, while they might be part of the subsequent actions taken during or after the drill, are not the immediate first actions and may lead to disorganization or delays if not in line with the proper response protocols.
