Alfa Signal Flag (Letter A) – International Nautical Signal Flag
The Alfa (A) signal flag is one of the most recognized flags in the International Code of Signals. Its meaning is clear and universally understood among mariners: “I have a diver down; keep well clear at slow speed.”
Featuring a bold white and blue swallowtail design, the Alfa flag has become an enduring symbol of the sea. Traditionally flown by boats engaged in diving operations, it is also a favorite among sailors, yacht owners, and coastal homeowners who appreciate its rich maritime history and striking nautical design.

Whether you are flying it from a sailboat, creating a signal flag arrangement on your yacht, or adding a classic maritime accent to your beach house, the Alfa flag brings authentic seafaring tradition to any setting.
