Here is a link the the SS 199 that I was talking about.
Here's another picture of the Tautog that, though its not dated, I'd bet is from the same day.
Maybe even the same 10 minute period. That could be the same vessel moving in the background, just a short distance farther along. The wind direction looks to be identical, too. It looks like the crew formed up aft as normal, then somebody remembered the CIC would be conducting his review from ashore and so they moved closer. The photographer was set up in the same spot in both picture.
