SS Thorfinn
A Legendary Gateway to the Ghosts of Chuuk Lagoon
The SS Thorfinn is more than just a dive boat; it is a maritime icon that has served as the premier "floating hotel" for explorers in Micronesia for decades. Originally built in 1954 as a Norwegian steam-powered whaler, this 170-foot vessel has been meticulously converted into a heavy-duty liveaboard designed specifically to navigate the historic and hauntingly beautiful waters of Chuuk (Truk) Lagoon.
Stepping aboard the Thorfinn is like stepping into a blend of maritime history and modern adventure. While many liveaboards focus purely on the utility of diving, the Thorfinn prides itself on its stability and spaciousness, providing a solid, comfortable base for divers who have traveled from across the globe to witness the world’s greatest collection of WWII shipwrecks.
Having stayed aboard the Thorfinn during my 2001 and 2003 expeditions, I found that her real charm lies in her stability and the incredible access she provides to the deeper wrecks of the lagoon. While modern liveaboards offer luxury, the Thorfinn offers an authentic, industrial-grade diving experience that puts you right in the heart of history.

The Thorfinn's Origins
The S.S. Thorfinn, a Norwegian-built vessel, was constructed in 1956 as a general cargo ship. Its initial purpose was to transport goods across international waters, navigating the vast expanses of the world's oceans. However, its destiny was to change dramatically, leading it to a new life in the idyllic tropical waters of Micronesia.
The transformation of the S.S. Thorfinn into a dive vessel began in the late 20th century. Recognizing the potential of Micronesia's pristine waters and the growing popularity of scuba diving, entrepreneurs saw an opportunity to create a unique and immersive experience for underwater enthusiasts. The S.S. Thorfinn, with its sturdy construction and ample space, was an ideal candidate for conversion.
Extensive renovations were undertaken to transform the ship into a floating hotel and diving platform. Comfortable cabins, dining areas, and recreational spaces were added to cater to the needs of divers and their companions. The vessel was equipped with state-of-the-art diving gear, and a team of experienced dive professionals was assembled to guide guests on underwater adventures.
Diving from the Thorfinn
Micronesia, a region of the Pacific Ocean composed of thousands of small islands, offers a diverse and stunning underwater landscape. The warm, crystal-clear waters are teeming with marine life, including colorful coral reefs, schools of tropical fish, and even large pelagic species like sharks and manta rays. The S.S. Thorfinn provides a unique opportunity to explore this underwater wonderland.
One of the most significant attractions in Micronesia is Chuuk (Truk) Lagoon, a sheltered body of water that is home to a vast number of shipwrecks from World War II. These wrecks, encrusted with coral and teeming with marine life, offer divers a glimpse into history while providing a thrilling and unforgettable diving experience. The S.S. Thorfinn operates in Truk Lagoon, allowing guests to easily access these dive sites and explore the underwater remains of the past.
The S.S. Thorfinn has had a significant impact on Micronesia, both economically and environmentally. By attracting divers from around the world, the vessel has contributed to the growth of the tourism industry in the region. This has led to increased employment opportunities, improved infrastructure, and the development of local businesses that cater to the needs of tourists.
Moreover, the S.S. Thorfinn has played a role in raising awareness about the importance of marine conservation in Micronesia. The vessel's dive professionals educate guests about the delicate ecosystems of the region and the need to protect these valuable resources. By promoting responsible diving practices and supporting conservation initiatives, the S.S. Thorfinn contributes to the preservation of Micronesia's natural beauty.

The Ghost Fleet of Truk Lagoon
The primary draw for any guest on the SS Thorfinn is the unparalleled access to the WWII shipwrecks of Chuuk Lagoon. Known as the "Ghost Fleet," these Japanese vessels were sunk during Operation Hailstone in 1944 and have since transformed into vibrant artificial reefs. Divers can explore iconic wrecks like the Fujikawa Maru, with its famous "R2-D2" air compressors, or the Shinkoku Maru, which is now encrusted in a breathtaking garden of soft corals and anemones.
Beyond the ships, the lagoon is home to downed aircraft and a surprisingly diverse array of marine life, including reef sharks, eagle rays, and massive schools of tropical fish. The SS Thorfinn’s unique position as a stationary "mothership" with smaller high-speed launch boats allows guests to visit a wider variety of sites with minimal travel time, ensuring you see the very best that this underwater museum has to offer.
