Diving the Hoyo Maru Wreck: A Unique Experience with the Thorfinn
Truk Lagoon, also known as Chuuk Lagoon, is world-renowned for its stunning array of sunken relics from World War II, and among these historic wrecks lies the Hoyo Maru. This Japanese oil tanker, resting in the tranquil waters of Truk Lagoon, offers divers a unique and memorable experience. With its upside-down position and rich coral growth, the Hoyo Maru presents a blend of history and marine life that draws divers from around the globe.
Diving with the Thorfinn, the iconic liveaboard moored in the heart of Truk Lagoon, provides unparalleled access to this incredible wreck, allowing you to explore its hidden depths and witness the captivating underwater world surrounding it.
The History of the Hoyo Maru
The Hoyo Maru was a Japanese oil tanker that met its fate during Operation Hailstone in 1944, a major U.S. Navy assault on the Japanese fleet anchored in Truk Lagoon. The attack resulted in the sinking of numerous vessels, including the Hoyo Maru, which now rests at a depth of 12 to 24 meters (40 to 80 feet). Unlike many other wrecks in Truk Lagoon, the Hoyo Maru is notable for its unique upside-down position, providing divers with an unusual perspective when exploring its structure.
While the Hoyo Maru was primarily an oil tanker, much of its internal structure and cargo have been preserved, creating an eerie underwater landscape where history and nature intertwine. The wreck has become a thriving artificial reef, with soft corals, sponges, and schools of reef fish making it their home.
Exploring the Hoyo Maru Wreck
Diving the Hoyo Maru is a remarkable experience, offering a mix of accessible depths and fascinating features for divers of all levels. The relatively shallow depth makes it suitable for both beginner and intermediate divers, while the upside-down position of the wreck adds an extra layer of intrigue to the dive.
Topside of the Hull: The most striking feature of the Hoyo Maru is its inverted hull, which rests on the lagoon floor. The hull is encrusted with a variety of soft corals, anemones, and sponges, creating a vibrant underwater garden. The coral growth attracts numerous small reef fish, making it a hotspot for underwater photographers seeking to capture the colors and diversity of marine life.
Engine Room and Propeller Area: For those comfortable with limited penetration, the engine room area offers a peek into the wreck’s mechanical heart. Although it requires careful navigation due to the wreck’s inverted position, divers can explore the engine components and other machinery, which are now heavily encrusted with corals. The propeller area, located at the stern, is another popular spot for exploration, providing a striking contrast between the steel of the ship and the soft corals and sponges that now cover it.
Marine Life and Coral Gardens: The Hoyo Maru is not only a piece of history but also a thriving ecosystem. The wreck is covered with colorful soft corals, sea fans, and hydroids, providing a haven for a variety of marine species. Divers can expect to see schools of anthias, butterflyfish, and angelfish, along with larger species like groupers and Napoleon wrasse. The occasional sighting of reef sharks and turtles adds excitement to the dive.
