Thorfinn includes as many of the wrecks as possible on each cruise ... but you'll need to do more than one cruise to see them all.  Here are a few of the popular favorites which you may be lucky enough to visit. Many of the wrecks are “Maru” or merchant vessels that had been left at anchor when the American attacks came.  A few had been fortified with anti-aircraft weapons and many carried important army supplies including Zero Fighter aircraft parts, tanks, torpedo shells, trucks and road supplies.  Bottles, cooking utensils, items from everyday life and personal artifacts can be found in several of the wrecks.

Fujikawa Maru – Immensely popular & easily accessible wreck, originally designed to carry both cargo & passengers, divers can penetrate the superstructure to see the remains of parts which were being transported …. tanks, propellers, wheels, artillery shells & torpedoes. You can see also visit the engine room, staterooms, and galley. Good corals, lots of fish, great photo ops.

Emily Flying Boat – This huge fighting plane was armed with machine guns, canons and bombs. After being hit by the Americans, the plane managed to fly to Truk, although several important Japanese officers on board had been killed. The pilot crash landed and a few of the crew survived. The impressive wreck is amongst the most popular in Truk for photographers.

Nippo Maru – This is a wreck which nearly every wreck diver dreams of visiting. Another favorite for photographers, the helm & telegraphs make startling subjects. You’ll also find a load of weapons & artillery, mines, gas-masks, shoes and more in the holds … trucks & a tank … Howitzers & an anti-aircraft gun on the deck

Amagisan Maru – Another ship originally used for both passengers & cargo, the Amagisan Maru offers a big photographic gun on her bow & one at the stern, plus aircraft parts, trucks and a car the hold. There’s also a tanker truck just at her side.

San Francisco Maru – Pre-requisition by the Japanese Navy, the San Francisco Maru carried passengers and cargo of minerals & coal. The haunting gun on the bow of the ship is one of Truk’s most photographed. The San Francisco also features several trucks & armored tanks, the usual artillery, torpedoes and bombs … along with airplane parts.
