Separate port & starboard embarking stations allow easy entries for 2 dive groups at a time to collect their personal dive gear and board the 2 dive launches without crowding each other. Each of the two state of the art 10m dive launches further add to the ease of diving with SS Thorfinn. Custom fitted with under-seat gear storage bins, easy access dive ladders, camera shelves and numerous safety features, as well as fresh water showers and fresh towels for after the dives, everything has been thought of to make life easy from start to finish.

The SS Thorfinn is a ‘Green Ship’, totally Eco-Friendly as it utilises the Island power plant waste lubes as its main heating fuel under boilers which are driving the steam propulsion system.

Micronesia Underwater
Micronesia Underwater


Scuba diving Chuuk (Truk) Lagoon is a mecca for wreck diving enthusiasts. With hundreds of World War II shipwrecks to explore, Truk not only offers amazing sights to be seen underwater but a rich history that goes along with it. There are fascinating dives to be done on these wrecks that have now become reefs, many of which still have the original war artefacts still on board.

One of the many benefits of exploring Truk Lagoon by dive liveaboard is the opportunity to explore the often-overlooked outer reefs. These offer a huge variety of fish life, with pelagic sightings and cascading coral walls disappearing into the depths. Don’t forget to keep an eye out to the blue to see if something bigger is passing by!

Divers can expect to complete up to 5 dives per day aboard the SS Thorfinn, meaning you really get to make the most of your time in Truk Lagoon.
