Speaking of required documents, Have you ever been asked to produce your Mariners license or Twic card? Last week while running a water taxi between the Battery and the USS New York anchored in New York harbor on 9/10/11, amongst the tightest security I have ever seen (Full TSA screening at the entrance to the terminal, bomb sniffing dog, two marines at the gangway in full battle gear and weapons, a navy liaison assigned to my boat as well as two Coast Guard Port Security Boats providing escort) no one asked me or my crew for any documentation, non at all! So who will ask you to produce a copy of your Nav Rules?
