If you're worried about having to go through formalities upon entering a U.S. port, the thing to do is to use your cellphone consistently during any cruise. The ID/locator in your cellphone provides the FBI a readily verifiable track of where you've been and when. (No warrants necessary, of course. It takes too long (15minutes?) to get those.) They'll be able to see at a glance that you've never left the USSR, (oops- typo.: U.S.A.) without even telling you they're checking. On the other hand, if you ARE worried about having to go through formalities upon entering a U.S. port, maybe there's a reason that you're worried, and that might that be enough to give them grounds to confiscate your vessel. November's coming. Think before you vote this time.
