Sea Tiger

Upright 58 m wreck, ten minutes off Waikiki

Area photo: mattk1979 · CC BY-SA 2.0

A 58 m ship put down as an artificial reef in June 1999 and now the closest wreck to Waikiki, ten minutes from the dock. She sits upright on sand with 40 m under her keel, but the dive itself is normally run between 24 and 30 m, and turtles, eagle rays and whitetip reef sharks have taken the ship over.

The dive

The ship stands upright on a sand bottom that lies at 40 m, and most of what divers come for sits well above that: the normal working range on the wreck is 24 to 30 m, along the deck and superstructure rather than down at the keel. That is the profile the shops plan, and it keeps a reasonable amount of no-decompression time on a wreck 58 m long.

Marine life has done the rest of the work since 1999. Green turtles use the structure, whitetip reef sharks patrol it, and eagle rays and large Hawaiian stingrays cross the sand around it; tiger sharks are an occasional sighting. Frogfish and moray eels are the small finds for anyone who slows down and searches the plating rather than swimming the length of the ship twice.

Season follows Oʻahu: South-shore boat diving runs all year; the North Shore reefs at Pupukea are only calm from about May to October and are dangerous in winter.

Know before you go

  • The sand alongside sits at 40 m, well below the 24-30 m working range, so it is easy to lose depth awareness off the edge of the wreck.

Questions divers ask

How deep is the Sea Tiger?+

She rests upright with the sand at 40 m, but the dive is generally run between 24 and 30 m on the deck and superstructure, so an advanced or deep qualification is the sensible minimum.

How far is the Sea Tiger from Waikiki?+

About ten minutes by boat from Waikiki Beach, the closest wreck to dive from there, which is why it is a standard first stop on south-shore charters.
