SS Thorfinn Quick Pitch

SS Thorfinn is one of the world’s best equipped liveaboard dive cruisers, having cruised/explored Micronesian waters since 1982. From operating base at Truk Lagoon, continuous non-stop diving is conducted 7 days per week, with up to 5 dives per day, on 5 differing sites – giving the opportunity to view 30+ wrecks during a one week visit. Thorfinn’s structures and safety gear comply with IMO (International Maritime Organization) standard.



Your trip’s ground transportation from airport or hotel to the ship is provided and included in your package. Friendly van drivers greet and transport you to a nearby pier for transfer by waiting dive tender out to the Thorfinn.

Direct boarding options are now also available, which  gives you more diving time onboard. The staff will greet you immediately after the airport for morning or afternoon arrivals, and then provides transfer to the ship at dive location, with full onboard services and facilities. Diving plans immediately begin the following day, until desired departure with free transfer back to airport or shore facility. 

Dive Overview

Truk Lagoon is considered by some to be the best wreck diving destination in the world, with over 60 World War II wrecks. The wrecks have a good amount of marine life on them, but some are quite deep, with the bottoms in the 100 - 150+ ft. range.

 Scuba Diving the Chuuk Lagoon

The 50 by 30 mile Chuuk Lagoon is among the largest lagoons in the world. Due to its geographical placement, its enormous size, and attractive conditions it was deemed a great spot for the Empire of Japan to house its main naval base during World War II. In 1944 the United States visited the area and sunk dozens of warships and other vessels as well as destroying hundreds of aircraft.

The great battles and tragedy that was experienced in the lagoon in 1944 can now be witnessed by scuba divers in what is one of the greatest concentrations of shipwrecks on earth. There are almost 70 wrecks within the lagoon alone.

While the wrecks are usually the main draw there is also no shortage of marine life that can be found in the area. A wide variety of fish, as well as schools of sharks and a good variation of corals, can be found as well.

During your days aboard SS Thorfinn, 5 dives are offered each day at short distances from the stable comforts of the large mothership. Thorfinn does not attach itself to the fragile wrecks in the lagoon, avoiding damage from this practice.

Durable twin-engine launches provide uncrowded diving for small groups, at separate dive sites avoiding the heavy silt outs caused by large group repetitive diving. This system provides a broad range of sites, always with the chance of returning to a favorite. Diving commences within 2 hours of daylight arrivals giving an opportunity of diving 30 or more wrecks over a standard 7 dive day week.

Diving, history, education and much more. An underwater adventure with SS Thorfinn is not one’s typical diving holiday. It is an unbelievable journey, an immersive experience of a region rich with history and a true privilege to see it up close. Similarly, it was a joy to see the dive operator work. With Captain Lance and his team, It was always safety first, instilling in me, as a diver somewhat new to high caliber wreck diving, a profound feeling of confidence and comfort. I was in very good hands. Captain Lance and his team deliver what they promise. He knows the fine details of every wreck by heart and is happy to share his knowledge. I learned so much about every aspect of every dive location that I felt very satisfied throughout the trip. Despite our extensive underwater exploration, there is still so much to see. I am already looking to the day when I will return to these waters and go again with Captain Lance and the team at SS Thorfin. I highly recommend this operator!
