HTMS Hanhaksattru
HTMS Hanhaksattru 312, a 44 m Royal Thai Navy fast attack craft, was scuttled at the mouth of Aow Mao on Koh Tao's east coast in September 2023 as a sister wreck to the Suphairin. It rests upright at about 20–24 m at the foot of a gently sloping bay. The young artificial reef already draws fusiliers, snapper and queenfish, with pufferfish and filefish around the structure. Its east-coast position means a wreck dive is possible whichever way the wind blows.
