FAQ

Two large 30ft covered RIBs will take divers out from Thorfinn, who will stay at various central anchorage within Truk Lagoon. Thorfinn and her fleet of dive boats provide a broad mobility offering the widest range of diving at Truk, taking small groups of diver to 5 differing daily dive sites adjacent to various anchorages.

Thirty or more wrecks can be dived during 7 dive days when following carefully selected Saturday-Saturday schedules.
Thorfinn steams to 2 or 3 differing anchorages with larger groups for closely adjacent dive access. With smaller numbers central anchorages are utilized within 5-10 minutes of most dive sites by fast dive launches.

Truk’s mid ocean location at 7 degrees North latitude is clear of continental monsoons and most tropical typhoons. Little predictable weather change assures a comfortable year round destination.

Best time is anytime. Daily temperatures range from 80 – 90° F ( 25 – 31 C ).
Rainfall averages 4 – 6 inches per month. NE trades bring 10 – 15 knot breezes from December through April, with weak and variable winds (doldrums) for balance of the year.

Sheltered waters of Truk Lagoon provide one of the world’s most comfortable dive locations with water temperatures of 28-29°C / 83-85°F, no thermoclines or currents and good visibility 40-100ft (12-30m). Underwater light conditions are normally good with a white sand floor reflecting sunlight, assuring good light at most depths for photography and video. Light skin suits are recommended for coral or wreck protection, and light thermal gear is often used after a few dives due to gradual body cooling as the week progresses. Experienced local guides assure added safety and professional assistance to best enjoy each site.

Five dives are offered each day at short distances from the stable comforts of the large mothership. Thorfinn does not attach itself to the fragile wrecks in the lagoon, avoiding damage from this practice.

Durable twin engine launches provide uncrowded diving for small groups, at separate dive sites avoiding the heavy silt outs caused by large group repetitive diving. This system provides a broad range of sites, always with the chance of returning to a favorite. Diving commences within 2 hours of daylight arrivals giving an opportunity of diving 30 or more wrecks over a standard 7 dive day week.

We offer a broad spectrum of 30 or more wrecks each week; some deep, many shallower. For divers favoring extended deep diving smaller open launches for 3 or more divers are available. The first dive of the day is to one of the deeper sites, progressing to more shallow throughout the day. If diving with regular single tank divers we would ask you to limit your dive to 60 minutes.
