YO-257
History of the YO-257
The YO-257, also known simply as "YO", is a former Navy yard oiler that once played a crucial role in the U.S. Navy’s operations during World War II. Built in the 1940s, the YO-257 was designed to refuel naval vessels at sea, a critical function during wartime. After decades of service, the vessel was decommissioned and eventually purchased by Atlantis Submarines, a company known for its underwater tours and commitment to marine conservation.
In 1989, Atlantis Submarines decided to create an artificial reef and enhance local dive tourism by sinking the YO-257 off the southern coast of Oahu. The sinking was carefully orchestrated to ensure the ship would settle in a location that would foster marine life and provide a safe, accessible site for divers. Today, the YO-257 rests on the ocean floor, serving as a vibrant underwater habitat and a popular dive site near Waikiki.

SEA TIGER
History of the Sea Tiger
​
The Sea Tiger, originally named MV Tharos, was a former Chinese trading vessel that was repurposed into a Taiwanese tuna boat. Built in the 1950s, it embarked on various voyages across the Pacific Ocean, laden with goods and stories of maritime adventure. However, its fate took a dramatic turn on January 7, 1999, when it was seized by the U.S. Coast Guard for illegal smuggling activities off the coast of Hawaii.
The ship's seizure was part of a broader crackdown on illicit trafficking in the region. Its operators, facing apprehension and legal consequences, chose a drastic course—to scuttle the vessel rather than face prosecution. On that fateful day, the Sea Tiger was intentionally sunk off the southern coast of Oahu, near Honolulu, where it found its final resting place on the ocean floor.
