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, so 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).

"Charted here" species were listed by our editors from the sources on this page. Counts are GBIF occurrence records: observations logged within about 5 km of the charted position since 1990, matched only against the species in our catalogue. They show what has been seen there, not a promise of what you will see.
