Honolulu, Hawaii, United States

San Pedro (Wreck)

The San Pedro is a small steel fishing trawler sunk in 1996 by Atlantis Submarines about a mile off Waikiki on Oahu's south shore, intended as a companion artificial reef to the much larger YO-257 oiler about 100 metres away. She rests upright on a sand bottom at 27 metres with the highest superstructure at around 21 metres. Most operators dive the two wrecks as a single profile, swimming the sand corridor between them at depth and completing the loop with a slow ascent up the higher of the two ships. The smaller wreck is heavily encrusted with hard coral, cup coral and sponges and provides a shaded refuge for resident species. Green sea turtles use both wrecks as long-term cleaning stations and several white tip reef sharks rest beneath the bow during the day. Other regulars include schools of pyramid butterflyfish, milletseed butterflyfish, scrawled filefish, taape (bluestripe snapper), Hawaiian sergeants, scribbled filefish and the occasional spotted eagle ray cruising past. Currents are usually moderate; visibility is reliably 18 to 30 metres because the lee side of Oahu is sheltered from north and east trade winds.
