This is one of my favorite wrecks in South Florida. I love that it's a natural wreck rather than an artificial reef. It lies at a depth that's perfect for my tech diving style. The wreck itself is fascinating, with its rudder standing upright, creating an impressive view. Inside the ship, you can still discover interesting details, like coal in the old boiler.
