What is the recommended action for the first swimmer to do after getting free?

The recommended action for the first swimmer after getting free is to contact the people inside the vessel. This approach prioritizes the safety and coordination of rescue efforts. By communicating with those on board, the swimmer can determine the status of individuals inside the vessel, relay information about the situation, and organize a structured rescue. This step is crucial, as the swimmer can provide critical information regarding the conditions, number of people needing assistance, and any immediate hazards present.

Engaging with the people inside helps to streamline the rescue operation, ensuring that actions taken are well-informed and effective. The other options may compromise the rescue effort by delaying vital communication or leading to disorganized attempts at rescue without first assessing the situation properly.
