How far do you have to stay away from a diver-down flag?
All vessels must navigate so as to avoid injury to the diver or interference with the vessel or floating object. DoT recommends where possible skippers maintain a distance of more than 100 metres from a vessel or buoy displaying a dive flag.
How far from a diver-down flag must a vessel be before operating at greater than idle speed?
State law requires that scuba divers and snorkelers display a diver-down flag to mark the diving area. Vessel operators must not operate within 50 feet of a displayed diver-down flag and must reduce speed to “idle speed” when within 200 feet of the flag.
Do all boats need a divers-down flag?

What is the 50 foot rule?
Let’s generalize and assert that most relationship interactions happen among people who live/work 50 feet apart, plus or minus an order of magnitude, say 5-500 feet.
