The out of commission Armed Transport San Quintin was scuttled at the out break of the Spanish American War (1898) in an effort to block the narrow shallow eastern channel into Subic Bay. She was positioned southeast of Grande Island and northeast of Chiquita Island where the water was only 10 meters deep. Sunk with her were two merchant ships whose identities were not recorded.

Due to her shallow depth, calm conditions and location, the San Quintin dive site is often used for training dives and as a second dive. It is often paired with the Japanese patrol boat, LST, barges or the El Capitan.

Dive boats drop anchor on this wreck in a sandy area east of the debris field of the ships. At tide changes there may be a mild to medium surface current that extends about 2 meters. Most the time the dive site itself experience no or just slight currents.

Time and storms has reduced much of the ship, the boilers at mid-ship, the bow and the stern are easily identified. Others portions seem to have broken up or buried in the sand. The ship has been underwater for over 100 years and is now well covered in corals. Juvenile fish are the most prevalent on this dive site.

Ten meters east and parallel to the San Quintin is a reef, that can also be dived as a part of this site.
