tad1, I think you're a little off, buddy.

The Hunley has been in a fresh-water tank to preserve it but was available for viewing (not very good views from what I've been told- the time my wife and I went to see it, it was closed). Article says they are redoing the tank for better viewing and to aid in the restoration. Next trip to Charleston I hope to see it.
Not the same article I read but close-
