What is the first action you should take if you witness someone fall overboard?

The first action to take when someone falls overboard is to throw them a flotation device and keep your eyes on them. This option is the most effective and safest response in a critical situation. By throwing a flotation device, you are providing immediate assistance that can help the person stay afloat and prevent them from sinking. Maintaining visual contact with the individual is crucial; it ensures you can monitor their position and condition while awaiting further help, which facilitates a more organized response.

Jumping in to rescue them can create additional safety risks for both the rescuer and the person overboard, as the water's conditions could pose dangers. Calling for help is important but should typically follow the immediate action of providing flotation to the person in distress. Turning the boat around quickly without ensuring the person has floatation support can lead to chaotic situations where they might be lost sight of, complicating rescue efforts. Thus, the best initial response combines providing immediate aid while ensuring effective visual tracking of the person in the water.
