HTMS Sattakut | Wreck Dive Koh Tao Thailand

Koh Tao's Largest Artificial Reef With Guns!

Koh Tao’s premier Wreck dive, “Sattakut” is now the largest Artificial Reef Wreck Dive For Koh Tao. HTMS Sattakut (LCI [Landing Craft Infantry] – 742) has become one of top wreck dives in Thailand and is one of the Koh Tao Dives Sites that is visited daily.

Into The Past - History

This ex US World War II Navy vessel (formerly known as the USS LCI (M)-739) was commissioned into the Royal Thai Navy in 1947 where it served until it was decommissioned in 2007. As a US Navy ship it took part in The Battle of Iwo Jima – one of the fiercest and most strategic battles between the USA and Japan during World War II.

A Costly Mistake

If At First You Dont Succeed...

On the 18th June 2011 after months of preparing and stripping the vessel of all toxins and hazardous materials, the Thai Department of Marine and Coastal Resources prepared purpose-sank the ship right next to Koh Tao Islands in the Surat Thani province of Thailand.

The first attempt of Sinking did not go as planned. After many hours of waiting, a small storm and some choppy waves the Sattakut found her final resting place on the sea bed but unfortunately on her side! At the beginning of August 2011, a salvage team successfully up-righted and moved the wreck to its current position which is south of another Koh Tao Dive Site Hin Pee Wee.

The Diversity Grows

Koh Tao is home to many artificial reefs which aid in Marine conservation. An artificial reef is classified as any human-made underwater structure, typically built to attract marine life in a chosen area. – Within the 1st year alone thousands of fish and different kinds of sea life have made HTMS Sattakut their home. All around the wreck’s structure you can see varieties of algae and invertebrates. The colonization of the wreck happened much faster than many had anticipated, and it continues to thrive and grow. Day by day this wreck dive site becomes more diverse and interesting.
