Thorfinn is a historic 58-metre liveaboard offering an exceptional diving experience in the legendary waters of Truk Lagoon, Micronesia. With more than four decades of experience exploring the region, the vessel provides convenient access to the lagoon’s world-famous Japanese World War II wrecks, with divers able to explore a remarkable variety of wrecks, reefs and underwater sites throughout their stay. Its spacious design, experienced local crew and strong focus on diving make Thorfinn an excellent choice for recreational, technical and underwater photography enthusiasts.

Accommodating up to 20 guests, Thorfinn offers 10 air-conditioned staterooms, with cabins located across the C, D and E decks. Most rooms feature double or queen-size beds with an adjacent single berth and private shower and toilet facilities, while three C Deck rooms share two shower rooms and two toilets. For a more luxurious stay, Thor’s Lair features a king-size bed, adjoining settee, private bathroom, walk-in wardrobe, bar fridge and entertainment facilities.

Onboard facilities include a spacious dining room, comfortable guest lounge with 50-inch LED TV, bar, DVD and reading libraries, shaded sun decks, outdoor seating and dedicated camera service tables with 110V and 220V charging points. Diving is conducted from two covered 10-metre tenders equipped with gear storage, camera shelves, fresh-water showers, dive stairs, GPS and VHF radios, while additional boats provide flexibility for smaller groups. Nitrox and custom gas blends are also available, making the vessel well suited to technical divers and underwater photographers.

Combining spacious accommodation, excellent diving facilities and unparalleled access to the wrecks of Truk Lagoon, Thorfinn offers an unforgettable liveaboard experience for divers looking to explore one of the world's most iconic wreck diving destinations.
