The blue and white flag is also known as which flag?

The blue and white flag, known as the Alpha flag, is an important symbol in the diving community and maritime context. This flag indicates that a diver is in the water and that boaters should keep clear to ensure the safety of the diver. When the Alpha flag is displayed, it serves as a warning to approaching vessels that they must exercise caution, as divers may be submerged nearby.

This flag's design consists of a blue field with a white diagonal stripe, making it easily recognizable. The Alpha flag is not interchangeable with the diver flag, which is a different design consisting of a red field with a white diagonal stripe. While both flags promote diver safety, the proper terminology and respective uses are important for clear communication on the water. Understanding the significance of the Alpha flag is crucial for both divers and boaters, as adherence to these signals enhances safety during diving activities.
