Operators must remain at least how far from military and naval vessels?

100 yards.

Operators must remain at least 100 yards away from military and naval vessels. Boaters should slow down to minimum speed when within 500 yards from any American naval vessel. If operators need to pass within 100 yards for some reason, they MUST contact the Coast Guard or U.S vessel, otherwise they will face 6 years in prison and a $250,000 fine since the Violation of the Naval Vessel Protection Zone is considered a felony.
