What does the Alpha Flag signify?

The Alpha Flag, which is the maritime signal flag, is specifically used to indicate that a vessel has a diver down and that there are divers in the water. It serves an important safety function, alerting other vessels to keep their distance for the safety of both the divers and crew members. Displaying this flag is crucial when divers are in the area, as it signals to surrounding vessels that they should exercise caution and avoid the vicinity where divers are operating.

While other flags also communicate important information, none of them relate to the presence of divers as explicitly as the Alpha Flag. The flags associated with other answers denote different situations, but the Alpha flag specifically aligns with the need for safety protocols during diving operations. This clear and specific use underscores its importance in maritime communication and safety practices.
