Trip Preparation Bulletin

The full enjoyment of your trip with us is our total objective, and the following information has been gathered to assist in this goal. Read carefully, and please contact us for any clarifications needed. Keep us informed with current addresses, phone numbers and email to enable us to contact you on any items of last minute information.

Diving Conditions:

Micronesia began developing as a warm tropic Pacific dive destination about 35 years ago, mainly with fame of Truk Lagoon’s sunken wartime fleet. The Thorfinn introduced a new approach to diving Truk about 1981 and bridged the large gap to remote and beautiful outer island atolls of Truk, Yap, and Pohnpei States.
Undived virgin atoll reefs provide a kaleidoscope of seldom seen species of fish, sharks, and coral in incredibly clear and warm waters.

At Truk, this ship introduced the ability to continuously dive on wrecks located close to various anchorages. Dive launches depart regularly from 8:00 AM to 5:00 PM and conduct after dinner night dives about 8:30 PM.
The ship provides comforts of home at the wreck sites with many interesting on board diversions during surface intervals.

Visibility on Truk wrecks can vary from 40 -100 feet or 12-30m feet depending on location and prevailing conditions. Strong emphasis applies to all wrecks in Truk Lagoon being designated as historic monuments.
Local law forbids disturbance or removal of artifacts from the magnificent relics of war. Violators will be prosecuted and possibly imprisoned.

Facilities & Comforts Aboard The SS Thorfinn:

The Thorfinn provides fine live aboard accommodations, and an entire ship’s crew strive to maintain these standards.

This remote location is occasionally strained for some supplies due to shipping delays and other unforeseeable events. Some items of supply from local merchants are grown on the islands. Please realize this remote location can lack some popular food items at differing times between supply ship deliveries.

The ship’s facilities, diving gear, boats, and compressors are well maintained and designed to suit demanding conditions of this remote location.

Ten tastefully furnished guest rooms are equipped for two person occupancy. Eight have large double or queen beds with adjacent single berths, Room 11 has two single berths and Thor’s Lair has a King bed with adjacent bed/settee. Seven rooms have private facilities, with three others sharing two adjacent showers and separate toilets.

Space is our specialty, consisting of a large ‘C’ deck guest lounge, separate ‘D’deck dining room, spa deck, sun deck with shade awning, camera service tables adjacent to lounge, and large deck areas of this deep draft stable ship adding to guest comforts and conveniences.

Wide selections of DVDs and music CDs are available at shipboard libraries for listening/watching pleasures.
A main lounge 50” hi-def LED TV feeds into a six speaker surround system. Multi-system DVD players cover wide ranging inputs, and convenient connection points permit direct inputs from guest data equipment.

Inmarsat’s new marine FBB 500 Satcom system provides speedy wi-fi Internet connections to worlds away, within limited bandwidths issued to each guest.

FSM Visitor VISA Forms are issued by airlines and processed by Immigration Clearance without charge. Your copy of this visa must be retained and is usually stapled to your identification for relinquishing on departure.

Clothing Suggestions:

Light clothing is suitable in this tropical environment. Shipboard informality dispenses with need for formal items.

A recommended checklist:


  • 2 pairs slacks
  • Cotton shirts
  • T-shirts
  • Shorts
  • Swimsuits
  • Tennis shoes or sandals
  • Sun hat
  • Windbreaker

Toilet Articles

  • toothbrush/paste
  • Suntan lotion
  • Skin cream/lip balm

Beach Towel

Insect repellent

Personal medication

  • Medical Kit
  • Paracetamol
  • Anti-motion tablets
  • Sudafed or other decongestant
  • Ear Eze (or other ear protection)
  • Band-Aids
  • Antibiotics (check with your doctor)

Sunglasses (spare)

Flashlight (extra batteries)

Extra batteries for cameras, etc,

Female guests are advised to include a mid-length skirt. It will be comfortable for shore visits, especially on traditional outer islands (see Customs and Conduct).


These waters abound with fine photography options. There are countless opportunities to view bright corals, fish, and shipwrecks in both wide angle and macro formats.
Bring sufficient memory cards, batteries, power adapters, strobes, and cameras needed along with back-ups.
A large LED TV monitor with DVD player is in the lounge for instant playback of your video/still footage.

Diving Equipment:

Dive Computer, BCD, regulator, masks, fins, snorkel, submersible pressure and depth gauges, wet suit (if desired), dive light (extra batteries), and repair kit are the divers’ responsibility, with a limited rental supply of most items aboard.

Tanks, weights, and weightbelts are provided on the vessel.

Light wet suits are optional in the 85 deg F (29 C) water, but do provide protection against coral and abrasions on the wrecks.

It is highly recommended to have critical equipment serviced and checked by a reputable service facility with emphasis on first and second stages of your regulators, hoses and gauges.

A supply of “O” rings and a check of your B.C. is also recommended. It is most distressing to have people arrive at this distant destination and then lose valuable dive time over malfunctioning equipment.

A limited rental supply of most gear except suits is available.

Diving Procedures:

Wreck diving under auspices of expert Trukese guides is conducted by mooring or anchoring our dive launches to wreck sites with divers proceeding up and down anchor or buoy lines. Whether moored or drift diving on reefs and at passes, expert dive guides will assist or lead divers while explaining and showing a site’s key interests.

Most regular diving is done on a no decompression basis, with mandatory stops at certain ascent points to assist in your safety. Technical divers are welcome to request extended deep or other considerations with Nitrox use. A privately maintained double lock re-compression chamber/facility is available at Chuuk, and dive insurance is mandatory to offset any fees assessed with a treatment.

The divemaster will oversee and profile each diver to keep track of their daily dive records. We ask everyone to record accurate bottom times and depths on our lounge log board after each dive.

Night divers should bring suitable dive lights and batteries. Spear fishing is not permitted.

Truk dive permits and related costs of $50.00 per person will be assessed onboard and is not included in your package.


Baggage insurance is highly recommended, and we recommend keeping critical items such as camera, regulator, mask, with you in a flight bag.

Clothing and dive gear is best packed in soft bags or duffel bags for onboard stowage. Please tag bags with your name, address and phone number in case of mishandling, and for easy onboard room placement by crew.

We advise you check baggage allowances and restrictions with your air carrier for the most up to date information and costs.

Health Precautions:

There are no current official requirements for vaccinations or inoculations, but you may wish to check with your doctor about any specific need.

Micronesia has very little pest or insect problems for a tropic location, but carry some antidotes for infections from light coral cuts and scratches.

Ear infections are easily contracted in warm waters and a vial of Ear Eze or equivalent for dropping in each ear at end of daily diving activities is highly recommended.

Sunburn can represent a great health risk and does require careful attention if you have not been exposed to the sun for some time prior to your trip with us. A good sunblock is essential.

Guests may consider bringing broadband antibiotics.


Every effort is made to assure a safe trip, but the purchase of a short-term trip cancellation policy, in case of unexpected changes in your plan is wise.

Diving Insurance is mandatory for diving onboard the Thorfinn.
Also recommended is accident, medical, and baggage insurance.

Customs & Conduct:

In order to preserve warm welcome given to visitors at remote islands of the Pacific, an insight of their customs will be helpful in making the most of your opportunity for cultural interaction.

Common sense can guide you much of the time but the following is a guide as to what to expect. Pacific islanders by nature are soft-spoken and reserved in their personal manner and it is recommended that a like conduct be displayed in their presence.

Do not appear unexpectedly in a village or gathering. Have a local person introduce you to the ranking chief and other prominent villagers.

Exposing the thighs is considered improper for females, therefore, skirts are recommended for shore visits. Onboard dress is casual and unrestricted.

During shore excursions, the Captain will arrange the formalities of introductions. In keeping with traditions of the island group, visitors may be asked not to walk in a particular part of the island or dive and fish in a particular area adjacent to the island, which we ask all guests to respect.

Visitors will delight in the warmth of the people and the gentle displays of friendship exhibited by offerings of coconuts and fruits and offers of a walking tour of their island. Please do not pick your own fruits unsolicited, as you may be trespassing. When encountering domestic scenes, ask for permission before taking pictures.

The people will be most cooperative but it could be found offensive to take pictures or video without first asking. On the other hand, don’t be surprised by people, especially the children, offering to be photographed and it is expected that pictures will be taken during performances by the islanders for their visitors.

Small tokens left as souvenirs with the people are a big hit such as soap, needles, combs, candies, fishing tackle, etc. and are very much appreciated.

Enterprising islanders will display handicrafts and shell for exchange or sale.

You will be delighted by young children whose natural curiosity will overtake their shyness to exchange stories and questions, often punctuated with fits of giggles.

Micronesians will not show open disapproval if you violate their social codes so we ask our guests to keep in mind this simple guide for the mutual benefit of a cultural exchange.


The U.S. dollar is the local currency. You can pay your onboard account with US$ cash, US$ travelers checks or credit card (VISA or MasterCard only – there is a 3% fee charged to offset higher merchant fees). Foreign currencies not are accepted as payments or at local banks.

Auxiliary outlets of 220VAC-60Hz power are additionally provided in seven rooms as well as at central 220V charging points via Australian type outlets. If you are traveling from the UK or Europe we recommend bringing power plug adaptors.

Airport Transfers to and from Ship:

Arrivals/Departures to and from airport:

Our office staff and/or crew will greet your arrival at airport and take you to a nearby pier (in our 10 seat van) where a dive boat will be waiting for final transfer to the anchored ship. This trip is repeated in reverse at trip end.

Arrivals/Departures to and from hotels:

Guests will be contacted at their hotel by our Office to confirm their transfer arrangements and timings. At the end of their trip guests will be transferred back to the hotel or airport as appropriate.


All foods served on board are of wide variety in generous quantity. Our two cooks conduct all baking, and produce a well-received fare. Special dietary requests will be handled to our best ability within range of any supply limitations.


Domestic water aboard is a product of shipboard desalination equipment. It is of the highest quality and perfectly safe to drink. We do ask guests not to waste water aboard as it is a valuable commodity.


Limited facilities are available, with a careful view to water consumption and availability.

The Crew:

The Thorfinn has a full Pacific Island crew complement of twenty, most of whom are Micronesian. Some may have a slight difficulty with English but usually comprehend quickly if spoken to in a measured manner. Their quietly reserved manner is the way of Pacific Island people…. to not appear obtrusive and forward speaking. Our high 20 crew to 20 guest ratio is to maintain the most attentive standard of service possible. Soon after boarding, the ship’s crew will place luggage in your respective rooms while we gather at lounge or spa to proceed with a full orientation on shipboard routines and dive procedures.


Tipping is not required aboard Thorfinn, but if you would like to reward the crew at trip end for a job well done, it will be graciously accepted. On board policy is for guests to give any contribution to two or three different departments together to avoid any chance of it not being divided evenly as the crew have set up between themselves.
