DIVING AND SNORKELING

State laws require all persons involved in diving or snorkeling operations to clearly mark the area using either the code alpha flag or diver flag as shown.
Boat operators should always stay a minimum distance of 100-200 feet from any boat displaying the alpha flag or any float showing the diver flag. Slow down to no wake speed and operate with caution anytime you observe underwater operations.

Tennessee Diving Laws

  • Boats must not operate within 50 feet of a diver's- down flag and a slow, no-wake idle speed restriction is automatically imposed within 200 feet of the flag.
  • A diver is any person who is in the water and equipped with a face mask, snorkel or underwater breathing apparatus.
  • All divers shall prominently display a diver's-down flag in the area in which they are diving and must surface within 50 feet of the flag. After dusk the flag must be illuminated so it can be seen from a minimum of 300 feet.
Any boat used as a necessary part of the diving operation must display, from its mast a diver's-down flag at least 18 inches x 24 inches in size and an international code flag Alpha so that they are visible from 360 degrees. After dark such boats shall illuminate their flags so they are visible from a minimum of 300 feet.
