The blue and white "Alfa" flag signifies what?

The blue and white "Alfa" flag is used internationally to indicate that a dive boat is restricted in its ability to maneuver. This flag serves a critical purpose in maritime safety, alerting other vessels to the presence of divers in the water nearby. When this flag is displayed, it signals to other boats that they should exercise caution, maintain a safe distance, and not approach the area where divers may be entering or exiting the water.

This is important not only for the safety of the divers but also for ensuring that other vessels are aware of the potential hazards associated with having divers in the vicinity. The flag's use is mandated by maritime conventions, making it a universally recognized symbol among mariners. Understanding the significance of the Alfa flag is crucial for both recreational and commercial boating activities, as it helps to prevent accidents and ensures the safety of everyone on the water.
