Fascinating history

The HTMS Sattakut has quite a fascinating history dating back to World War II, where it served as a Navy troop carrier, notably during the battle of Iwo Jima. In 1947, it was gifted to the Royal Thai Navy, and in 2011, it found a new home in Koh Tao after being generously donated by the Royal Thai Navy, in partnership with the Department of Marine and Coastal Resources. After thorough cleaning, it was intentionally sunk the same year.

Start your exploration at the ship's bow, just beneath the gun platform. These entry points will guide you down a set of stairs and into the front cabin. As you proceed forward, you'll reach the middle section of the ship, directly under the bridge.
Here, you'll encounter a lengthy corridor that leads you straight to the ship's stern. While there are smaller and deeper rooms beyond this point.
