Today we took a 4 hour cruise on a replica stern-wheeler in Ft Myers, FL; licensed for about 400 people. There is a sign on the pier by the gangway, saying: NOTICE The U.S. Coast Guard is enforcing certain maritime security requirements for access control, including SCREENING you and/or your purse bag or other container. YOU AGREE to allow us to screen you and/or your purse bag or other container, as may be required by boarding or remaining on board this vessel. YOU MAY NOT board or remain on board this vessel unless you allow us to screen you and/or your purse bag or other container as may be required. Of course, there was NO screening of any kind. So, what does it mean? I notice the sign does not mention any specific statute or Coast Guard regulation, and it doesn't even say what items migh be prohibited: if you get screened and find a firearm, do they just say "have a nice day", or throw you in jail for 20 years?
