Dive Truk Lagoon, departs from Weno
Year Round 7 or 10 nights, from 2500 Euro
Experience the Wreck Diving Capital of the World with your favourite liveaboard fleet and delve deeper into history!!. The majority of the 61 sunken ships and aircraft from the Japanese fleet lie well within recreational limits and experienced divers will find plenty of sites to choose from during the course of our liveaboard safari. Our 7-night or 10-night itineraries allow divers to explore not only many of the famous wrecks but to experience some superb reef diving also. There are numerous channels that cut through the reef which serve as hunting grounds for reef sharks and schooling pelagics which all add to the wonder of diving Truk.

Siren Fleet Liveaboard safaris in Truk Lagoon will operate throughout the year commencing in November 2014. Truk is best known for its world-class wreck diving and with over 61 wrecks, tightly packed into a coral reef lagoon, it is easy to appreciate why divers travel to this area time and time again. During WWII the Japanese fleet used Truk as one of their main staging points for attacks on the allied forces but in 1944 the America led “Operation Hailstorm” surprised the fleet resulting in the plethora of dive sites which we can see there today. Many of the wrecks lie within recreational diving depths, however the S/Y Truk Siren will also offer Tec diving facilities for those wishing to delve deeper in the wreckages and take a closer look at history.


The 40 metre S/Y Truk Siren luxury diving liveaboard built in 2009 will be refitted in 2014 to offer our guests Tec-diving facilities. She offers ample room for 16 guests in 8 cabins which are either fixed double or twin bed, however we wish to offer flexibility therefore 2 cabins have the option to be converted from twin to double. There are also 2 triple bed cabins which may be used for full charter trips to suit the needs of our guests. The outdoor dining area offers a superb setting for all your meals and the dive deck is spacious with individual set up stations, storage drawers for all your personal items and large rinse tanks for camera gear and torches.
Since her launch in 2009 we have also improved facilities for underwater photographers and videographers, providing both indoor and outdoor designated areas for charging and preparation of your camera and video equipment.

Built on the Indonesian Island of Sulawesi, she is a traditional “gaft-rigged Phinisi” handcrafted from ironwood and teak. Built by divers for divers the S/Y Truk Siren is a modern and spacious diving liveaboard.

Aboard the S/Y Truk Siren we shall welcome up to a maximum of 16 divers on each trip. This ensures abundant space for all guests.

Truk Lagoon Dive Site Highlights
Fujikawa Maru The armed cargo ship rests upright on the sandy bottom at 34m (110ft), rising up to 5m (15ft). She is one of the largest vessels at over 130m (430ft) in length giving plenty to explore, decks are encrusted with corals as are her guns on the aft deck. Whilst 6 holds contain a plethora of artifacts from the war, including Mitsubushi aircraft wings and Zero fighter propeller blades.

Fumitsuki the Japanese destroyer sits upright in 38m (130ft) of water and is covered with corals attracted a wide variety of marine life. Her upper deck is at 21m (80ft) allowing recreational divers of advanced level plenty of opportunity to explore the wreckage.

Shinkoku Maru – A large oil tanker, now rests upright on the bottom encrusted with corals, sponges & hydroids. From the bridge you can see into the engine room whilst the galley still holds many utensils on the large stove. Small guns, mounted fore and aft are also covered with corals making this one of the most colourful and spectacular wrecks to be found in Truk.

Nippo Maru Lying at a depth of 50m (150ft) this site is best suited to tec divers, providing plenty to explore within the wreckage and without including antitank guns and mines, and a tank (pictured left). The bridge, helm and superstructure remain chiefly in tact and provide a good place to off-gas whilst watching the glassy sweepers that congregate there.

Heian Maru – The largest ship in the lagoon, the Heian, originally used as a cargo ship, is 165m (510ft) in length and lies on her port side in 34m (150ft) of water. Within her holds diver may find torpedoes, shells and even the occasional periscope.

Susuki Destroyer – best known for its engine room, this patrol boat once boasted an array of gas masks and other fascinating artifacts, many of which have since been removed. However some can still be found scattered about the deck and it remains a stunning wreck dive site. The bow is in just 3m (10ft) of water, shallow enough to see whilst snorkeling, with the stern propeller at 15m (50ft).

San Francisco Maru – The passenger & cargo ship, weighing 5,831 tons, lays upright at a depth of 63m (195ft). Here divers can see the remains of many well preserved war-relics including three large tanks which rest on the deck at between 46-55m (150-175ft).

Gosei Maru – A submarine tender carrying torpedoes starts in just 3m (10ft) and drops to 33m (120ft) within which can be found many personal artifacts, serving as a reminder of those who lost their lives during the battle.

Rio de Janeiro Maru lies on her port side at a depth of 34m (110ft) with holds containing numerous artifacts from bottles to guns. Once a luxury passenger vessel she was converted to a cargo carrier for wartime and now provides divers with an easy exploration both inside and out.

Shark Island – possibly the most famous reef dive in Truk, is a fantastic cleaning station for reef sharks and at just 18m (60ft) is perfect for some “off-gassing” in the afternoon after a morning of wreck diving

Itinerary & Schedule

Truk Lagoon – Liveaboard Diving Itinerary

Departing from Weno, our 7-night and 10-night liveaboard dive trips on the S/Y Truk Siren take you directly to the main concentration of wrecks lying within the bay. The S/Y Truk Siren will moor over the deeper wrecks allowing for our divers to descend easiy down the line directly to the wreckage. Tec divers will benefit from the support of the “mothership”, whilst our 2 dinghies are able to shuttle less experienced divers to the shallower sites and offer reef diving as an alternative to the wrecks.

Many of the wrecks are “Maru” or merchant vessels that had been left at anchor, some 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, serving as a reminder to the visiting divers of those who lost their lives during the battle. The more gruesome reminders of the conflict, such as human skulls, have since been removed and may now only be seldom seen in the deeper reaches of the wreckages.
