I've been wondering this for a while, and I haven't been able to find an answer in my cursory research, so I thought I'd throw the question up here. On the bow of the great ship, there's a feature that I've always wondered about. Specifically, what is it? It's the round thingie indicated by the arrow in this photo.
What is that? Anybody know? My geek brain tells me that this is the Titanic's main deflector dish, but I know that ain't right. (Or, if that is right, man, did that thing ever fail spectacularly.)
