When free, the first swimmer out should contact the people inside by

• A. Tapping the hull
• B. Shouting
• C. Waving
• D. Signaling with a light

Answer: (A)

The signal should be tapping the hull because it provides a direct, unmistakable cue that is reliable in rough water, wind, and engine noise. Tapping the hull is a physical signal that the people inside can detect immediately, even if visibility is poor or audio signals are hard to hear. Shouting can be drowned out by waves and motor noise, waving can be misread or go unnoticed, and signaling with a light depends on darkness and working equipment. A tap on the hull gives the crew a clear, simple way to know a swimmer is ready to be retrieved and where to approach safely.
