from Wikipedia

diver down flag, or scuba flag, is a flag used on the water to indicate that there is a diver below. Two styles of the flag are in use. Internationally, the code flag alfa/alpha, which is white and blue, is used to signal that the vessel has a diver down and other vessels should keep well clear at slow speed. In North America, it is conventionally red with a white stripe from the upper left corner to the lower right corner.

Purpose[edit]

The purpose of the flags is to notify to any other boats to steer clear for the safety of the diver and to avert the possibility of a collision with the dive boat which may be unable to maneuver out of the way.

Signal flag Alpha[edit]

A diver getting ready to dive in front of an alpha flag.

As a code signal the International maritime signal flag Alpha (or “Alfa”, signifying the letter “A”) has the meaning of “I have a diver down; keep well clear at slow speed”,[1] used to indicate the presence of a diver in the water and is used in all countries other than the United States of America, Canada, sometimes Italy, and countries within the US’s diving culture sphere of influence such as certain countries within the Caribbean.

A rigid replica of the ‘Alpha’ flag is required to be displayed by any vessel engaged in diving operations, when restricted in her ability to maneuver, if the size of the vessel makes it impractical to display the shapes and lights required by the International Regulations for Preventing Collisions at Sea (IRPCS) Rule 27.[2][3]

Although the presence of the ‘A’ flag may afford some protection for divers in the vicinity of the vessel displaying the flag, the intention of the rigid replica required by IRPCS Rule 27 (e) is to warn other vessels of the danger of collision. This marks a distinction between the ‘Alpha’ flag and the red and white diver down flag.[4]
