Why dive here
With 173+ marine species recorded in the area - including blacktip reef sharks, eagle rays, giant moray eels, whale sharks and clownfish - Premchai Wreck offers some of Similan Islands's richest wreck diving. Water ranges 29-31°C, warmest April, May, June.
The Premchai Wreck is one of those sites we always make time for on the way back to Tap Lamu. It’s not the deepest wreck out there, topping out around 20 metres, but it offers a solid intermediate dive. This old tin dredger, which went down in 2001, lies mostly upside down, and that unique orientation gives it a real character. We love poking around the darker spaces. You'll spend your dive exploring the hull, now encrusted with hard corals and big clams. We’ve spotted honeycomb morays tucked away in crevices, their patterns distinct against the metal. It’s a site that feels lived in, too; schools of fusiliers often mill above the deck, shimmering in the shafting light. The Premchai is a perfect dive for those who appreciate the history of a wreck, combined with a good chance of finding some interesting macro life without pushing deep limits. It’s a rewarding dive, especially as a last hurrah before heading back to shore.
