<\/p>\n

Koh Tao wreck diving<\/strong> offers an experience unlike any other on Thailand’s diving island. With three military wrecks now resting on the seabed, Koh Tao has established itself as one of the best wreck diving destinations in the Gulf of Thailand. The HTMS Sattakut \u2014 a World War II veteran scuttled in 2011 \u2014 and its two newer companions, the HTMS Suphairin and HTMS Hanhaksattru, both sunk in 2023, form an extraordinary trio of artificial reefs. Moreover, Koh Tao wreck diving<\/strong> with The Divers Boat means small groups, attentive multilingual guides and daily departures from Mae Haad pier.<\/p>\n

The HTMS Sattakut<\/strong> is undoubtedly the star of Koh Tao wreck diving<\/strong>. Originally a US Navy landing craft infantry vessel (LCI-724)<\/a>, this 48-metre ship took part in the Battle of Iwo Jima during World War II before being transferred to the Royal Thai Navy. In June 2011, it was deliberately scuttled to create an artificial reef near Hin Pee Wee, off the north-west coast of Koh Tao.<\/p>\n

Today, the Sattakut rests upright on the sandy bottom, its superstructure reaching up to 18 metres. Thanks to its many well-lit entry and exit points, penetration diving is accessible to Advanced Open Water certified divers. On board, two historic guns \u2014 a 76 mm and a 40 mm \u2014 serve as reminders of the ship’s military past, while marine life has colonised every part of the structure. Indeed, this wreck is also an ideal site for Deep Diver<\/a>, Nitrox and Wreck Diver SSI specialty courses<\/a>.<\/p>\n
