Along with the USS Yorktown, Patriots Point has the USS Laffey a destroyer and the USS Clamagore, a submarine. Both ships a interest to tour and see the exhibits on them.
First is the destroyer the USS Laffey.
The tour of the submarine USS Clamagore gives you a view of life on a submarine.
I do recommend if you got to Patriots Point that you tour both the USS Laffey and USS Clamagore.
