SS Thorfinn, a fully outfitted live-aboard diving vessel catering to scuba enthusiasts of every kind amidst the pristine Micronesian seas since 1981.

Guests who choose  SS Thorfinn for their liveaboard adventure will find a service that places a strong emphasis on convenience and flexibility. The team is committed to delivering a seamless and accommodating experience from beginning to end.

One notable feature of the service is its flexible boarding options. Guests can choose to be picked up from a location of their preference or delivered to their desired destination pre/post-tour. Thorfinn provides airport services and transportation to and from shore facilities, prioritizing guest comfort and convenience.

However, what truly sets this Liveaboard apart is its exceptional A to A (Airport to Airport) advantage. This unique offering provides guests with up to 1.5 extra dive days at the cost of just one extra day, eliminating the need for shoreside logistics or additional expenses. This feature underscores Thorfinn’s commitment to enhancing the diving experience.

Recognizing the diverse schedules and preferences of their guests, Thorfinn also offers open boarding times on any date. Additionally, guests have the flexibility to choose their desired length of stay on daily fares, tailoring their liveaboard adventure to suit their individual preferences.

About the boat; the SS Thorfinn offers a range of amenities and experiences for its guests.  On 'D' deck, a dining lounge seats 22 guests, providing customized breakfasts and chef-curated daily meals. Two talented chefs prepare delectable dishes, including daily baked goods, to cater to individual dietary preferences. Guests can also explore an extensive library of books.

The 'C' deck salon features a 50" multi-system LED TV with a DVD player, a CD player with an IPOD connection, and a surround sound system with six speakers. It's a cozy spot with ample windows, perfect for relaxation. The bar offers reasonably priced beverages.
Aft of the main guest lounge on 'C' deck, guests can enjoy stargazing and relaxation. With soothing music and a drink in hand, it's an ideal place to unwind after dives or late at night.
For relaxation, a spacious tub designed for 12 guests offers a soothing experience with powerful jets. It's filled with ocean water supplied by the ship's coolant flows.

During the day, 'B' deck is a popular hangout with sun loungers for sunbathing, and an overhead shade canopy provides a cool respite.
Ten air-conditioned staterooms comfortably house 20 guests in double occupancy. Each room is equipped with in-room vanities, TVs, DVD players, indirect lighting, and roomy closets. Some rooms offer double or queen-size beds with adjacent single berths and private showers and toilets.

The ship deploys two state-of-the-art 10-meter/30-foot launches with twin 150 hp 4-stroke engines for swift and quiet transport to dive sites. These launches offer custom features such as seat edge lighting, fresh water showers, and camera shelves. Two additional speedy 24-foot fiberglass boats ensure diverse dive sites for separate dive parties.

For camera enthusiasts, there are spacious camera service and storage tables with compressed air guns. The main lounge features a large plasma TV for viewing footage, and dive guides can assist with camera handling.

Efficient dive operations are ensured with two separate boarding stations for Port and Starboard, refilled cylinders, separate filling stations for air and technical blending, and optional gear valet services and camera assistance.

The SS Thorfinn boasts a dedicated local dive staff for expert underwater guidance and large lifting derricks for each boat to ensure efficient maintenance, making for a seamless and enjoyable diving experience.
