Most of us know Hawaii for its beautiful beaches and crystal clear waters. But, did you know Oahu, Hawaii is home to some of the most thrilling wreck diving sites in the world? These sunken vessels, intentionally sunk or lost to the depths of the ocean, have become havens for marine life and stunning underwater landscapes. Whether you’re an experienced wreck diver or a beginner looking to explore the depths of the ocean, Oahu has something to offer.
In this blog post, we’ll dive into the top five wreck dives in Oahu and explore the unique features and marine life that make these sites a must-see for any diver.
The Sea Tiger
The Sea Tiger is a popular wreck diving site located off the southern coast of Oahu, Hawaii. This wreck sits upright on the ocean floor at a max depth of approximately 120 feet (36 meters). The wreck is intact and can be easily explored by experienced divers. It’s not recommended for beginners due to the depth and strong currents. The ship is 189 feet (57 meters) long and 28 feet (8.5 meters) wide, making it a substantial site to explore.
The Sea Tiger wreck is now home to a large variety of marine life. Expect to see schools of tropical fish, octopus, moray eels and green sea turtles. Divers who are trained to do so can explore the various rooms and compartments of the ship, including the engine room and the bridge. The unique underwater ecosystem that has developed around the wreck makes it a must-see dive site. Due to the depth of the site, many divers choose to use Enriched Air (Nitrox) to extend their dive time.
The YO-257
The YO-257 wreck is one of the most popular dive sites in Oahu, Hawaii. This wreck was originally a Navy fueling vessel built in 1943 and was later decommissioned in 1982. In 1989, it was sunk off the coast of Waikiki, Hawaii. This created an unbelievable artificial reef and wreck dive site. The YO-257 now rests at a depth of approximately 100 feet (30 meters) and is home to must-see species.
The YO-257 wreck is well-known for its clear water and excellent visibility. This makes it an ideal site for both beginners and experienced divers. The ship is approximately 175 feet (53 meters) long and offers many opportunities for divers to explore its various compartments and rooms. Divers who are trained to do so can swim through the wheelhouse and cargo holds and observe the unique marine life that has made its home around the wreck.
It’s important to have proper training and experience before attempting to dive this wreck. If you’re an experienced diver, then the YO-257 wreck is a must!
The Corsair Plane Wreck
The Corsair Plane Wreck is a World War II-era fighter plane that was sunk off the coast of Oahu in 1946 for training purposes. The plane sits at a depth of approximately 115 feet (35 meters) and has become a popular wreck diving site in Hawaii.
The Corsair Plane Wreck is an ideal site for both beginners and experienced divers. This is due to its relatively shallow depth and clear water. The plane is about 30 feet (9 meters) in length and is surrounded by incredible marine life, including colorful coral and a variety of fish species.
Divers can explore the cockpit and wings of the plane and observe the unique ecosystem that has developed around the wreck. The Corsair Plane Wreck is also a popular site for underwater photography due to the clarity of the water and the unique features of the plane. Additionally, because the plane is a World War II relic, it is important to respect the site and not disturb any artifacts.
The Mahi
The Mahi wreck is a former Navy minesweeper that was sunk intentionally off the coast of Oahu in 1982. Now, it’s a wonderful artificial reef and popular dive site. The ship sits on the ocean floor at a depth of approximately 85 feet (26 meters).
This wreck is relatively small, measuring 157 feet (48 meters) in length. However, it offers a unique diving experience with its intact structure and is home to some of the most amazing species of marine life. It’s definitely a must-see for any wreck diving enthusiast. That being said, divers should be aware that the Mahi wreck is located in an area with moderate currents. It is important to have proper training and experience before attempting to dive the site.
The San Pedro
With a maximum depth of 85 feet (26 meters), the San Pedro wreck lies adjacent to the YO-257 wreck. This wreck is 111 feet (34 meters) in length. Originally built in Japan and operated by a Korean fishing company, the ship caught fire in 1975 while transporting bait, food and other cargo to a fishing fleet off South Point. Despite sustaining significant damage, the ship was towed to Keehi Lagoon and remained anchored there for nearly 20 years. Later, the San Pedro was intentionally sunk by Atlantis submarines in 1996 to create an artificial reef and diving site.
The San Pedro wreck is a prime location to spot white tip reef sharks. Divers trained to do so can also embark on a fascinating exploration of the ship’s various compartments and the unique aquatic ecosystem that has developed around the wreck. It’s important to note that the site is subject to moderate currents and divers should possess the necessary experience and training. Furthermore, as the wreck is a protected area, it’s crucial to respect the site and avoid disturbing any artifacts.
