CM 91793TS - Koh Tang & Offshore

We're often asked about our favourite wrecks in Southeast Asia, and CM 91793TS, out at Koh Tang, makes the list for its sheer atmospheric presence. This isn't one of those carefully prepped artificial reefs; this fishing vessel went down unexpectedly, and the tragedy of it still lingers in the silence. It’s a deep dive, down to 45 metres, making it better suited for experienced wreck divers comfortable with technical profiles. You'll descend onto a hull that looks like it just settled, listing hard to port. The structure is largely intact, with fishing nets still draped over sections, swaying with the mild current. We’ve found barracuda often patrol the bridge, and the open holds are home to schools of snapper, their silver scales glinting in your torch beam. The wreck is slowly becoming a true reef, with sponges and small corals starting to colonise the metal. Keep an eye out for nudibranchs, particularly around the bow. We love the feeling of exploring a wreck that has a genuine story, rather than just being a sunken object. It’s a somber, beautiful dive.
