Submarines Hawaii and sunk as an artificial reef off Waikiki in 1989. The ship
rests upright in 30m (100 ft) of water with the main deck about 25m (85 ft).
It has been prepared for diving with many large access holes cut through the

the wreck. Wave to the Atlantis submarine as it passes by on its tour.
Visibility is normally 30m (100 ft) +. There is sometimes a strong current at

rigged to mooring buoys on the wreck.
A typical dive profile is 27m (90 ft) for 20 minutes. The YO257 is one of
the more popular boat dives if you are diving the South Shore. In 1996, a new
ship, the San Pedro, was sunk within 45m of the YO257 as an additional dive
