Bangsak Wreck

The Bangsak Wreck is one of the deeper wreck dives of the Andaman coast, tucked off the Thai mainland between Khao Lak and Ranong and far enough from the usual tourist circuit that most of the teams you meet on the boat are divers specifically after the wreck rather than incidental visitors. The vessel sits upright on a sand bottom in around 30 metres, with the deck level coming up to roughly 20 to 22 metres. The profile fits squarely inside advanced recreational limits, but the depth, the remoteness and the occasional lively current mean this is not a casual afternoon out. Approach is by dive boat from the Khao Lak piers, typically as a dedicated single wreck trip. Entry is a negative drop straight onto the descent line and a direct descent to the deck, where the group regroups before moving on. The wreck itself is still in a coherent state, with the hull and railing obvious, the superstructure recognisable, and open holds that reward curious divers with a cautious swim through. Nitrox 32 is strongly recommended, and a PADI Wreck Diver specialty with some experience in limited penetration is the honest baseline for anything beyond the exterior tour. The marine life has taken full ownership. Large schools of yellowtail snappers and fusiliers cover the upper structure, honeycomb morays and giant morays occupy the deeper nooks, batfish hang still in the water column over the bow, and a resident school of batfish likes the stern. Large groupers sit under the overhangs. On a good day the blue around the wreck fills with small jacks chasing baitfish, and the occasional reef shark will drift through on its own business. Conditions are at their most workable from November through April. Monsoon closes the wreck from May to October, and the boats switch routes elsewhere for the season.
