Site details

The USS Spiegel Grove, a 510-ft Navy landing ship dock scuttled in 2002 six miles off Key Largo, is one of the largest artificial reefs in the world. She rests upright in 130 ft of water with her superstructure starting around 60-65 ft, serviced by seven permanent mooring buoys inside the Florida Keys National Marine Sanctuary. Strong currents and sheer scale make it a genuine advanced dive, while the labyrinthine interior is a renowned technical/wreck-penetration playground; goliath grouper, jacks and bull sharks patrol the structure.

boatwreck

Depth (deck ~65 ft, sand at ~130 ft), strong and unpredictable Gulf Stream currents on the mooring lines, overhead environment — extensive penetration possible only with wreck/technical training and lights/reels, narcosis at depth, boat traffic. Multiple diver fatalities have occurred inside the wreck.
