What minimum distance must be maintained from a u. s. navy boat?

The minimum distance that must be maintained from a u.s. navy boat is: 100 yards
U.S navy boats have to keep themselves under siege to prevent potential attacks from the sea. If you're traveling to close to the U.S navy boat, they may misjudge you as a threat to the ships and could take unwanted action

Sorry i don’t know the answer myself
