About this site

This Sail Rock lies within the Adang-Rawi Archipelago off Ko Batong, in Satun province in far southern Thailand, near the Thai-Malaysian maritime border in the Andaman Sea. It is a different site from the better known Sail Rock (Hin Bai) off Koh Tao in the Gulf of Thailand, and Satun's islands are typically reached by boat from the mainland or from nearby island piers along this less developed stretch of the Andaman coast. The site is a rocky formation reaching a maximum depth of around 20 metres, rated intermediate, with strong current and generally great visibility, and that current is the main hazard divers should plan around. Barracuda, batfish, damselfish, mackerel, nudibranchs, snapper, trevally and whale sharks are regularly encountered here, and divers have also reported angelfish, fusiliers, grouper, leopard or zebra sharks, manta rays, humphead wrasse, octopus, pufferfish, scorpionfish, sweetlips and wrasse.
