Dive flags

Know the dive flags

Boats and divers fly these flags to show that divers are in the water. Learn them before your first open-water dive. Rules and distances vary by country, so check local law.

Flags, rules and emergency numbers

International Code flag A (Alfa)

Swallow-tailed, white at the hoist and blue at the fly. Means “I have a diver down; keep well clear at slow speed.” The international signal for vessels engaged in diving operations.

Diver-down flag

Red with a white diagonal stripe, often flown on a float. Marks an area where divers are in the water; divers may surface outside it. Used mainly in North America and not an international (COLREGs) signal.

Go professional and keep every dive

Your scuba logbook and the professional logbook are one account. If you train as a technical or commercial diver, your scuba dives are already there. Nothing to move, nothing lost.
