What should be done if you see a diver down flag?

A diver down flag signifies that there are divers in the water below, and it serves as an important warning to boaters. When you see this flag, the safest and most responsible action is to remain at a safe distance and keep a lookout for the divers. This ensures their safety and minimizes the risk of a collision.

Remaining at a safe distance allows you to monitor the area for any divers that may surface unexpectedly, while also providing them with the space they need to operate safely. Keeping a lookout is crucial since divers may not be visible from the surface, and spotting them quickly can prevent accidents.

The other choices would not adequately address the safety needs of both the divers and the boaters. Speeding up to pass could endanger the divers, changing course toward the flag could place your vessel directly over where divers are located, and ignoring the flag poses serious risks to diver safety.
