Mary Celestia
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
The Mary Celestia ran Union blockades into Confederate ports until September 1864, when Bermuda's south-shore reef ended her career within sight of land; one man, the ship's cook, was lost. What remains reads like a cutaway diagram of a paddle steamer: both iron paddle wheels, one upright and iconic, plus boilers, anchor, and bow frames on clean sand at sixteen meters. In 2011 archaeologists opened a sealed bow compartment and recovered intact perfume bottles and wine, a find that made international news. She is compact, historic, and photogenic, an essential Bermuda dive.
