HTMS Sattakut
HTMS Sattakut is a 48 m World War II US Navy landing craft that served the Royal Thai Navy and was scuttled off Koh Tao's west coast in 2011. It sits upright on sand with the deck from about 18 m and the seabed near 30 m; two guns remain on deck. Schools of fusiliers and snapper swirl over it while groupers, barracuda and cobia hang around the hull. The neighbouring Hin Pee Wee pinnacle (6–18 m) is usually used for the second half of the dive and the safety stop.
depth: 18–30 m
