Nov 7-21, 2026




Due to the popularity if the Truk Lagoon Rec•Tec excursions I have planned two Rec•Tec's for 2026. That's two separate two week back to back trips diving the 90'-130'+ dive sites followed by a deep week of 130' to 200'+ dives. Please join me for an epic wreck diving expedition to Truk Lagoon. I've been diving, filming & photographing the famed Japanese WWII wrecks since 2003 and am presently one of the captains of the finest luxury liveaboard dive vessel in the world, the M/V Odyssey. There is no safer, spacious and more luxurious a vessel to experience the wrecks of Truk from. I will be stepping aside as captain for these trips to focus all of my energy and expertise to deliver to you a dive trip of a lifetime. Read on for further details.

US Planes Over TrukUS Planes Over TrukUS Planes over Truk Lagoon during Operation Hailstone February 17-18, 1944. On February 17th & 18th of 1944, United States Naval forces conducted the most daring carrier based aerial raid in history on the Japanese naval stronghold of Truk Lagoon in Micronesia. More than forty Japanese ships ended up at the bottom of the lagoon turning it into a modern day wreck diving mecca for sport divers the world over.  To dive Truk once is but to scratch the surface of what lies below.

The first week of this dream itinerary is focused on diving the wrecks that have made Truk Lagoon famous. The Shinkoku, Hoki, Nippo, Fujikawa and the San Francisco Maru are all scheduled. Although I call it a "Rec" week technical diving is most certainly welcome to those with the proper training. Depths range from 90' to 160' average 110'. The second week is dedicated diver who desires to dive the deeper less frequented challenging wrecks such as the Amagisan, Aikoku, San Francisco and Shotan Maru's. Depths will range from 120' to 210'. There are so many wrecks in Truk that you can dive two per day for three weeks and still not see them all!

(After the April 4 date check out the 2 week trip to the Philippines both land based and liveaboard.)

The Truk Odyssey 

Since 1999, the Odyssey and her highly experienced crew have been taking avid divers in the lap of luxury to dive the wrecks of Truk Lagoon. The 133' vessel is tricked out to meet the most discerning divers needs. The luxury spacious staterooms with individual climate control will provide the perfect place to rest up between dives and get a good nights sleep. The delicious food served in the large dining room will not disappoint. Odyssey is a perfectly designed dive platform with everything the recreational and technical diver could ask for. Individual dive lockers, outdoor shower, rinse tanks and extra large camera table are but a few of the amenities on deck.  In addition, get truly spoiled with a diver lift that raises you from the water to the swim deck. No climbing! Excellent for divers with heavy gear or physical issues where climbing ladders is difficult. There are no details overlooked on the Odyssey.
