I just checked the web site "Florida Scuba News" and they have not updated yet for this month. I have not heard of this sinking either. You may have some news that other can help verify. But, if you want to dive wrecks, there are plenty at depths most NE divers like. Duane, Bib, Eagle, Thunderbolt, Busch, Caymen. There are several excellent tech dives such as the Wilkes Barre. Florida Scuba News has two articles on deep tech wreck dives (but not in the Keys) that are a good read.
Find out more for us on the "Tacoma". Keep in touch too for the Spiegle Grove and the AF researech ship (near Key West).
