The Bibb is the sister ship of the Duane but it's on its side. There is usually a pretty strong current and you'll probably want to stay in the "shadow" of the wreck for most of the dive which will put you in about 110 FSW. You'll want to bring plenty of gas and hope that the boat you're on will allow you to go into deco. Or, you'll just get about a 15 minute dip on it. It rarely gets dove for those reasons.

I dove with these guys: http://www.silentworldkeylargo.com/. They're Brits, just like Lottie, and very nice to do business with

Here is my report on my last trip to Key Largo for reference: http://tinyurl.com/3xwr6y
