Rules for TN divers and boaters
Thanks to Eddie Cline for finding this information for us.
For Divers in Tennessee
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.
For Boaters in Tennessee
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.
