When someone falls aboard what action should the skipper take?

When someone falls overboard, the skipper should immediately shout "Man overboard!" to alert the crew and maintain awareness of the situation. The vessel should be turned around in a controlled manner, ideally using a figure-eight maneuver to return to the person's location quickly. The crew should be instructed to keep an eye on the individual in the water and throw them a flotation device if available. Once the boat is in position, the skipper should ensure the safety of the crew while executing a rescue.
