Built in Japan around 1946, the 111’ long San Pedro was a Korean owned long-line fishing vessel which operated off the Big Island, mostly targeting Swordfish and Tuna. In 1975, while carrying bait, food, and other cargo to an offshore fishing fleet, it caught fire off South Point. Badly damaged, it was towed to Keehi Lagoon. It sat derelict for years before being intentionally sunk next to the wreck of the YO-257 by the Atlantis Submarine Co. in 1996 to add more sights for their underwater tour.  The San Pedro sits in around 80’ of water with the deck around 60’.
