Truk Master

Truk Master 786 opt

The sleek & sturdy Truk Master underwent a total re-fit in 2016. She accommodates a maximum of 16 divers (11 to Bikini Atoll), taking them to experience the wonders of the wrecks of Truk Lagoon & Bikini Atoll.

 A word from Dom :  "I think the choice of this vessel for Truk Lagoon & Bikini Atoll is ideal.  Totally refitted, sturdy and stable, with tech diving capacity, she offers everything a wreck diver desires.".... Dominick Macan

With 3 full decks and a fly bridge, you'll finld plenty of space for relaxation and good accommodation for your dive equipment and camera preparation. 

Guest cabins span the 3 decks and all are en-suite with individual air conditioning units.

On the upper deck, you can chill out in the combination lounge & bar area with its plasma screen.  Or, grab some sun - or perhaps a nap in the shaded section - on the large stern sun deck.  The bow deck is where you'll find the hot-tub.  After a punishing tech dive, it's the perfect option.  And, It's just in front of the spacious master suite.  Nice to know in case you're the lucky couple in the suite.

On the main deck, in addition to 4 cabins, you'll find the kitchen and comfortable dining room .... and to the rear a dive deck with loads of room.

And, the Captain welcomes you to join him at the fly-bridge, from where you can soak up some sun & the stunning views of the islands of Truk Lagoon.


The United States tested 67 nuclear weapons on the Marshall Islands between 1946 and 1958. ‘Castle Bravo’ in 1954 is the best-known. This 15-megaton TNT hydrogen atomic bomb was a thousand times more powerful than the bomb dropped on Hiroshima. It left a crater in the lagoon of 2 kilometres wide and 76 metres deep. 

For over 60 years, the nuclear ghost fleet (as these wrecks are known) lay in crystal clear waters which over time developed an abundance of marine life with thriving reefs and corals. Bikini Atoll was opened for diving in 1996, allowing divers to experience some of the most unique wreck diving in the world.  The diving is available to technical divers only and you need to be minimally normoxic trimix certified.

There will be 2 technical dives offered per day. For safety, the minimum surface interval between dives is 4 hours and it is mandatory to take an afternoon off mid-trip (optional land tour and beach BBQ will be offered instead of diving). Travel time between Ebeye Island and Bikini Atoll is 23-34 hours depending on conditions. It may be possible to dive the German heavy cruiser Prinz Eugen wreck near Kwajalein as a check dive before sailing overnight to Bikini Atoll.

Travel & cruise logistics

The itinerary is built around the United Airlines flight from Honolulu, Hawaii that serves both Kwajalein and Majuro. Depending on your itinerary, we highly recommend you use this flight to get to and from Kwajalein and/or Majuro. Passengers travelling from the Marshall Islands are required to pay an airport departure tax, for Kwajalein this is currently 20US$. This varies from airport to airport and must be paid in US$. 

At the time of writing, no visa is required for entering the Marshall Islands for US citizens, EU countries, Canada and most other Western countries. Nevertheless, it is imperative that you check for any updates and changes with their nearest Marshall Islands embassy or consulate as requirements evolve based on world politics and health concerns.
