An adult male stands on the deck of a vessel, identified as being in the waters off Don Sak, Thailand. He faces the camera, slightly angled to his left, with a light smile. He has short dark hair and a short beard/stubble. He wears a white short-sleeved t-shirt with thin horizontal red and blue stripes and black shorts; a thin, light-colored string bracelet is on his right wrist. Both hands rest on a black metal railing that delineates the vessel's edge from the turquoise-green water, which exhibits surface ripples from movement. In the mid-ground and background, a series of steep, heavily vegetated limestone karsts and mountains rise from a distant coastline. The sky above is partly cloudy. Structural elements of the vessel, including white metal beams and an overhead panel, are visible to the man's right.
