Boating Basics: On the Water

Diver-Down Flags

Scuba divers or snorkelers display a flag to mark their diving area. Vessels not engaged in diving should stay well clear of areas displaying the “diver down” flag or vessels displaying the “code flag alfa.”

The diver-down flags are:

Divers Flag: A rectangular red flag with a white diagonal stripe is required if on state waters
Divers Flag: Red square flag with white diagonal stripe

Alfa Flag: A blue and white International Code Flag A (or Alfa flag), usually flown from a vessel and used on federally controlled waters
Alfa Flag: White and blue vertically striped flag
