When the diver down flag is observed, what should vessels do?

• A. Halt and anchor near the flag
• B. Ignore and continue
• C. Speed up to pass quickly
• D. Keep at least 100 feet away

Answer: (D)

When you see a diver down flag, the area is active with divers in the water, so you must give them wide space. The flag marks a safety zone, and boats must stay at least 100 feet away in every direction to protect divers from propellers, wakes, and sudden boat movements. So slow to a safe speed and steer clear of the marked area until the flag is removed or you’re well beyond the zone. Stopping near the flag or speeding through would put divers at risk, and ignoring the signal is unsafe. The correct approach is to maintain a generous distance—at least 100 feet—and proceed with caution.
