Thanks. I looked for that and couldn't find it The recreational maximum operating depth (MOD) for most recreational divers is 130 ft. Apparently, specialized divers can go 164 ft. So the ship is not at risk from "divers" unless you want to classify a submarine or other submersible as a "diver". Bad reporting!
I agree.
Pro divers regularly visited the Andrea Doria which i believe is on average around 250 ft.
They have to use trimix gas and can only stay down for like 15-20 minutes and a long wait to decompress on the way up.
I imagine the serious pros have gone deeper...
