Crew Boat Mary Lou - Florida Springs
The Crew Boat Mary Lou in Florida’s springs is one of those wrecks we keep coming back to. It’s not just a sunken boat, it's a piece of local history, and the springs give it this almost ethereal quality. We love diving it early on a weekday; you get the place mostly to yourself, and the morning light piercing through the spring water feels incredible. The wreck itself is a small crew boat, maybe 20 metres long, sitting upright on a sandy bottom. There are open sections, the wheelhouse, and the engine room, all accessible for a careful peek. We always find juvenile largemouth bass lurking in the shadows, and sunfish dart out from behind rusty bulkheads. Visibility is generally excellent, 20 metres or more, which makes for some great photo opportunities. It's an ideal dive for anyone comfortable with confined spaces who wants to explore a wreck without the ocean's surge. Bring a good light, not just for looking into the darker corners, but to really make the details pop against the spring's natural green tint.
