Premchai Wreck
A former tin dredger, twin of the Boonsung, that sank in 2000–2001 off the Thai Muang coast south of Thap Lamu and now lies almost upside down in one piece. The keel tops out around 12–15 m and the sand is at about 20–22 m, so most of the dive is spent between the two. Juvenile barracuda, fusiliers and lionfish swarm the hull, scorpionfish and moray eels hide in it, and ghost pipefish and nudibranchs turn up on closer looks. Visibility is often limited by the coastal tides.
depth: 12–22 m
