A – ALPHA: The signal flag ALPHA when flown by itself, lets other vessels’ crews know that a diver is down below and to keep a clear distance, traveling at a slow speed. The ALPHA signal flag is in the design of a swallowtail – a V-cut at the end of the flag creating two points. ALPHA and BRAVO are the only two signal flags with the swallowtail design. Be sure to check in later to learn about the signal flag BRAVO.
F – FOXTROT: The signal flag FOXTROT when flown by itself, alerts nearby vessels that the boat is currently disabled, unfit for travel, and needs to be in communication with someone to receive assistance.
Together: When the two are used together, the flag ALPHA is placed above the flag FOXTROT, and the meaning of the flags changes to “I do not intend to abandon my vessel.” This flag sequence is typically used when the vessel has taken on some level of damage, like developing a list, or other low-threatening hazard. The vessel at this point is either still mobile or can be saved from further ruin.
