Pacific Master Liveaboard, Micronesia (Truk Lagoon), Marshall Islands (Bikini Atoll)

The Pacific Master is a 30-metre steel-hulled motor yacht built in 2004 and custom-designed for liveaboard diving.

With a spacious dive deck, dedicated dive platform, technical diving facilities and a camera area, the Pacific Master provides a comfortable base for exploring historic shipwrecks and underwater sites. The Pacific Master liveaboard combines recreational wreck diving in Micronesia with specialist technical diving expeditions in the Marshall Islands.

Diving Facilities

The Pacific Master is equipped for recreational and technical diving, with a spacious dive deck providing direct access to a dedicated dive platform. Individual dive stations give guests designated areas to prepare and organize their equipment, with storage space for personal diving gear. The dive deck also features individual toilets, freshwater showers and equipment rinse tanks, making it convenient to freshen up and prepare for subsequent dives.

Three compressors and two tenders support the diving operations. The standard diving package includes a single 11-litre (AL80) cylinder with air fills, weights, a weight belt and a delayed surface marker buoy (DSMB). Additional cylinders and specialist technical diving equipment are available for an extra charge.

Nitrox is available on Truk Lagoon itineraries for an additional fee and is not included in the standard diving package. Standard Nitrox is offered at 28%. Rental diving equipment is also available at an additional charge and must be pre-booked to ensure the required equipment and sizes are on board. Recreational equipment options include regulators, BCDs, wetsuits, masks, fins and boots. BCDs and wetsuits are available for rent on Truk Lagoon itineraries only, while dive computers are offered separately. Dive torches are not available for rent on the Pacific Master.

For technical divers, the vessel provides specialist equipment and cylinder arrangements to support different diving configurations, including twinsets, sidemount and rebreather setups. Technical gas requirements must be requested in advance, as availability depends on the equipment and gas supplies required for the itinerary.

On Bikini Atoll itineraries, the Pacific Master is configured specifically for technical diving, with dedicated facilities including a deco-bar. These expeditions are designed for experienced technical divers exploring deeper historic wrecks.

Itineraries & Destinations

The Pacific Master operates in two distinctive Pacific diving destinations: Truk Lagoon in Micronesia and Bikini Atoll in the Republic of the Marshall Islands. Both regions are renowned for historic wreck diving, but the itineraries differ in their diving requirements and experience levels. Truk Lagoon welcomes suitably qualified recreational and technical divers, while Bikini Atoll is dedicated to experienced technical divers.

Truk Lagoon, Micronesia

The Pacific Master offers 7, 9 and 10-night liveaboard itineraries in Truk Lagoon, one of the Pacific's most recognised wreck-diving destinations. The lagoon contains more than 60 historic shipwrecks, many belonging to the Japanese Imperial Navy fleet sunk during World War II.

Resting at depths ranging from recreational to technical diving limits, these wrecks preserve remnants of wartime cargo, including aircraft parts, tanks, torpedoes, trucks and ammunition. Everyday objects such as bottles, cooking utensils and personal belongings can also be found among the remains, offering a fascinating insight into life aboard the vessels. Over time, many of these historic wrecks have become coral-encrusted artificial reefs, attracting marine life and creating additional underwater habitats.

Truk Lagoon itineraries are suitable for recreational and technical divers with the necessary qualifications and experience. The 10-night itinerary requires at least an Advanced Open Water certification or equivalent, together with a minimum of 50 logged dives. Additional deep-diving qualifications are recommended for recreational divers, while technical divers should hold appropriate technical certifications.

On typical diving days, guests can enjoy up to four recreational dives, with a night dive potentially replacing the fourth daytime dive when the vessel is anchored within the lagoon. The 10-night itinerary offers the possibility of up to 34 dives, depending on the schedule and operating conditions. Technical diving facilities are also available for suitably qualified guests wishing to explore deeper wrecks.

Bikini Atoll, Marshall Islands

For experienced technical divers, the Pacific Master offers 10, 11 and 13-night liveaboard itineraries to Bikini Atoll in the Republic of the Marshall Islands. This remote destination is internationally recognised for its collection of historic naval wrecks, commonly known as the Nuclear Ghost Fleet.

The wrecks are associated with Operation Crossroads, a series of nuclear weapons tests conducted between 1946 and 1958. The lagoon contains the remains of battleships, submarines and destroyers, most notably the aircraft carrier USS Saratoga. These historic vessels now rest beneath the water among thriving reefs and marine habitats.

Unlike the recreational diving itineraries in Truk Lagoon, Bikini Atoll is exclusively suited to technical divers, as the wrecks lie beyond recognised recreational no-decompression limits. The Pacific Master accommodates a maximum of 18 divers on these itineraries and offers two technical dives per full diving day. The minimum requirements include technical diving certification to at least 45 metres, a minimum of 100 logged dives and previous wreck-diving experience. Open-circuit and rebreather divers must hold the appropriate technical qualifications for their respective configurations. Divers planning to penetrate wrecks must also possess dedicated technical overhead-environment certification and experience.

The diving schedule includes a minimum surface interval between dives, as well as a mandatory afternoon away from diving midway through the trip. This provides an opportunity to join an optional land tour of Bikini Island and enjoy a beach BBQ instead of diving. Depending on the itinerary and conditions, some departures may also include an opportunity to dive the Prinz Eugen wreck near Kwajalein or explore the Airplane Graveyard before continuing to Bikini Atoll.

Non-diving Activities

Beyond the underwater exploration, Bikini Atoll itineraries include an opportunity to experience the island itself. During the mandatory afternoon away from diving, guests can join an optional land tour of Bikini Island and enjoy a beach BBQ. This provides a change of pace during the technical diving expedition and an opportunity to discover the destination above the water.
