Florida Specific: Diver Safety

  • The divers-down warning device must contain a divers-down symbol.  The symbol is a red rectangle or square with a white diagonal stripe.  If the symbol is a rectangle, the length may not be less than the height or more than 25% longer than the height.  The width of the stripe must be 25% of the height of the symbol.  If multiple stripes are displayed, all of the stripes must be oriented in the same direction.
  • The size of the divers-down symbol depends on whether the divers-down warning device is displayed from the water or from a vessel.  On the water, the divers-down symbol must be at least 12 x 12 inches in size.  On a vessel, the symbol must be at least 20 x 24 inches in size.  
  • When displayed on a boat, the divers-down warning device also must be displayed at the highest point of the vessel so that its visibility is not obstructed in any direction.
  • If the divers-down warning device is a flag, the divers-down symbol must be on each face and have a wire stiffener or be otherwise constructed to ensure it remains fully unfurled and extended, even when there is no wind or breeze.
  • If the divers-down symbol is a buoy, the buoy must have three or four sides with the divers-down symbol displayed on each of the flat sides.  The buoy must be prominently visible on the water’s surface and can’t displayed on the vessel.
  • Boaters must make reasonable efforts to stay at least 300 feet away from divers-down warning devices in open water and at least 100 feet away in rivers, inlets, or navigation channels.  Boaters approaching divers-down warning devices closer than 300 feet in open water and 100 feet in rivers, inlets, or navigation channels must slow down to idle speed.
  • Divers-must make a reasonable effort to stay within 100 feet of a divers-down flag or a buoy within rivers, inlets, or navigation channels and within 300 feet on open water.
  • A divers-down warning device may not be displayed when divers are out of the water.
