We've gotten off topic (Rockport) here. Maybe a mod could split this off to t anew thread?
It's interesting reading, but I don't see it having a huge impact. I know nothing about the "cruise ship" at Rockport. Is it a "cruise ship" under the act "cruise ship" means a vessel to which Part 2 applies and that has sleeping facilities for over 100 persons who are not crew members, but does not include a ferry.? Or is it a daytrip ship? Does it land in the US? Is there any other "commercial" traffic in Rockport? After reading most of the posted link, I see the "cruises" being affected much more than divers. They may need to erect security checkpoints and hire people to "search" those boarding. I wonder who owns the dock where the cruise ship is and who'll pay for fencing, cameras, security guards, etc, required.
I don't know about anyone else, but I AM NOT submitting to a body search, such as is required for aircraft nowdays, in order to take a scenic cruise along the seaway. I can just imagine my parents reaction (my dad especially) if they had to go through a metal detector, and empty pockets, remove shoes (he wears very stiff shoes of the type with metal in the sole), etc, to go on a river cruise.
