This old tin mining vessel sank in 1984 and rests on a sandy bottom at a depth of 20 meters. Over the years, there have gathered a huge amount of marine life around it. Large schools of fish and more special mooray eels have colonized this wreck. The western part of the wreck has been nicknamed nudibranch paradise, as there are a huge variety of colorful nidubrachs. The whale shark also visits here regularly.
MV Sea Chart 1 was en route from Burma to Vietnam with 1,200 wooden logs on board when it faced rough weather conditions off Khao Lak in August 2009 and sank as a result. The 84-meter-long and 12-meter-wide wreck now rests on its starboard side at a depth of 40 meters. The wreck still has those logs visible and it has gathered a lot of marine life around it.
Premchai is also an old tin mining vessel that was intentionally sunk as a dive site in 2001. The wreck is not as full of life as the Boonsung wreck, but year after year more marine dwellers have found a home here. The wreck is located close to the coast of Tablamu so visibility is greatly affected by the coastal tides. On a good day, the visibility here can be 10 meters, so the wreck is primarily a good macro dives. Here you can see a lot of different small macro critters like crabs, shrimps and nudibranchs.
Founded in 2013, Khao Lak Wreck Park has two old Army ships sunk in it; T-13 and HTMS Prathong 715. In addition to these, there are several army trucks as well as other artificial structures in the park. There are plans to sink tanks, train carriages and old aircraft here in the future to increase the attractiveness of the site.
