Besides GWX, the closest I've come to the real thing was a tour of the USS Torsk, a Tench class diesel sub. She wasn't underway, of course, so I didn't get a feel for how that would have been. Boy was she cramped, though! She's one of the big fleet subs too, I don't want to even imagine how bad it must have been on, say, a German type VII boat.
Though, it was still cool to touch a real WWII sub.
