Sea Tiger
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 Sea Tiger's first career ended in federal custody — she was seized smuggling migrants — and her second began in 1999 when she was cleaned and scuttled off Honolulu as a dive attraction. She sits upright with a slight lean, wheelhouse open to careful swim-throughs, holds patrolled by bluestripe snapper in dense yellow rivers, and a strong supporting cast: green turtles on the deck, spotted eagle rays banking off the rails, whitetips in the shade of the hull. Slightly deeper and moodier than the YO-257 down the coast, she rewards nitrox and a disciplined clock. Photographers prize her silhouettes against the surface glow.
The moment you come for: Snapper rivers through the holds; eagle rays off the rails; atmospheric wheelhouse frames.
Topography: A 57-meter former trading vessel upright on sand, deepest at the stern
Entry: Charter run from Kewalo Basin; descend and ascend on the mooring line.
Know before you splash
Hazards: Depth at the stern nudges recreational limits; penetration beyond open swim-throughs needs wreck training; mind the mooring in current.
Conservation: Purpose-sunk and fish-rich — leave the structure and its tenants untouched so the reef keeps compounding.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
