I think using "common sense" goes a long way when dealing with the case you mentioned.
I''m sure that if you are almost 100 yards from a vessel that you''re supposed to stay clear of, that you could find a way to communicate with it.
Since you already said you operate out of Norfolk, I happen to know that you can get in touch with the base Commander or OD BEFORE you get underway.
To put things in another light, what should the watchman do if he sees an unauthrized boat aproaching his ship and is now within the 100 yard perimeter? Remember, he does not know if the lives of his crewmates are potentially at risk. Also remember, we ARE at war.
If my son was on that ship, and you violated the DO NOT ENTER ZONE without prior permission - well, I hope you have plenty of life insurance for the loved ones you will leave behind.
