A History of Fire and Water
Built in Japan approximately around 1946, the San Pedro served a long career as a commercial fishing ship operating off the Big Island of Hawaii. Her surface career came to an abrupt end in 1975 when she caught fire. For nearly 15 years, the charred hull sat in various locations around the islands until she eventually sank in Keehi Lagoon.
In 1996, the state of Hawaii sold the vessel to Atlantis Submarines for the nominal sum of $1, plus reimbursement for environmental cleanup costs. The total investment to prepare and sink her as an artificial reef was approximately $360,000. Today, she rests in roughly 85 feet of water, providing a habitat for coral and fish.
Current Conditions and Marine Life
Since her sinking in 1996, the ocean has taken a toll on the San Pedro. Powerful storms and currents have collapsed much of the superstructure and moved the wreck slightly from its original position. The ship is slowly flattening out, creating nooks and crannies that are perfect hiding spots for marine life.
Divers frequently encounter huge Hawaiian Green Sea Turtles resting on the deck or under the remaining overhangs. It is also common to spot Whitetip Reef Sharks patrolling the perimeter and Eagle Rays gliding through the current overhead. The site is a dynamic example of how nature reclaims man-made structures.
