SS Thorfinn (Seaward Holidays Micronesia)

A 1,100-ton ship permanently moored in the lagoon as a floating resort, so divers reach most of the main wrecks by fast launches in about 10 minutes and can do up to five dives a day in small groups. Flexible-length stays from airport to ship, nitrox on the Sunrise plan, rebreather and tec plans, PADI courses; the operator describes it as a floating resort rather than a cruising liveaboard.
