Situated only a few hundred meters of the southern end of Khao Nai Yak, near Tublamu Harbour - the Premchai wreck is a great choice for a half day trip or as an alternative to the sloping reefs and submerged pinnacles of the Similan islands. This old tin dredger sank only 9 years ago and is now a well established nursery for a large variety of marine life. And it seems like every year it attracts more and more fish. Still in one solid piece, you can see the crack along the hull that sank her. Due the massive amount of nets and cables, penetration is not allowed. The wreck lies at an average depth of between 16-20 meters, with the top of the wreck extending to around 15 meters.
