Discover HTMS Sattakut Wreck Dive Site Koh Tao

One of the largest and most successful Artificial dive site projects on Koh Tao is HTMS Sattakut that was sunk in 2011 and has fast become one of the most popular dive sites on the island.

Located 30 metres southeast of Hin Pee Wee, HTMS Sattakut lies on the sea bed in 30 metres of water with the top of the wreck at 18 metres.

This dive site is suitable for Advanced Open Water divers and is the perfect site to obtain your PADI wreck diving certification.

HTMS Sattakut – Advanced Open Water Divers

At almost 50 metres long, HTMS Sattakut is 7 metres wide and has two large cannon guns with lots of entry and exit points for those qualified to enter inside.

The stern of HTMS Sattakut is the deepest point lying in approximately 30-32 metres, depending on the tide.

At this part of the ship underneath the rear cannon gun, you can find one of the entry points that leads to a long corridor with different rooms on both sides.

When you swim alongside the hull of the wreck, you can look through the portholes to see inside each room.

Good Buoyancy at HTMS Sattakut

Even though there can be adequate light to see inside, we recommend taking a torch with you when diving the Sattakut.

Above the hull lies the wheelhouse or steering cabin that consists of two levels, with the top of the tower being the shallowest part of the HTMS Sattakut at about 18m below sea level.

Just below the wheelhouse, towards the bow of the ship, you can find 3 more entry points for wreck penetration dives.

As you swim further along towards the bow, you will see the big gun appear at the front of the ship with 2 more entry/exit points below that lead downstairs under the deck.

PADI Wreck Specialty Courses – HTMS Sattakut

Once you have completed your tour of the HTMS Sattakut you can continue on to Hin Pee Wee, which lies straight north from the bow of the shipwreck and is less than a 1-minute swim away.

When you start your dive at the stern of the shipwreck, you can see a small school of One-Spot Snapper just below the cannon.

Inside the wheelhouse, you will often find various marine life such as Brown Sweetlips together with Giant Groupers and occasionally a Sea Snake may pass through hunting.

Whalesharks have been known to pass by the wreck and if you have a really good day, the visibility may be good and you can see the whole wreck from either side or from above – an awe-inspiring sight.

Deep Dive Site Koh Tao

Make sure to maintain good buoyancy and trim if entering the wreck and do not touch the wreck as Scorpion fish have been known to hide out near the doors and portholes.

For Wreck Specialty divers who are penetrating the HTMS Sattakut you can look out for Durban Dancing Shrimp on the staircase as you descend down inside the wreck.

On a good day, HTMS Sattakut is an excellent dive site for training Specialty courses such as Deep, Nitrox, Sidemount and for Advanced divers completing a wreck adventure dive.
