USCG Bibb (Wreck) - Florida Keys
The USCG Bibb is one of those wrecks that really feels like a proper ship, not just a pile of metal. She sits upright, largely intact, and when you drop down, you quickly get a sense of her scale. At 33 metres, you're deep enough to feel that pressure, but the visibility here is usually pretty good, often 20 metres or more on a calm day. We love how the pilothouse and parts of the engine room are still accessible. You can glide through, imagining the crew, and then pop out to find a huge goliath grouper staring at you from under a deck overhang. Our favourite part has to be the stern, where the prop is still in place, covered in sponges and gorgonians. Look closely, and you’ll spot schooling jacks swirling around the mast structures, with barracuda often hanging motionless in the slight current. We'd suggest going early, before the afternoon boat traffic kicks up, to really appreciate the quiet grandeur of this old cutter. It’s an intermediate dive, perfect for those comfortable with depth and overhead environments, offering a real dive into history and thriving artificial reef life.
