Plan this trip with AI →The Poseidon Liveaboard sails from Phuket, Thailand, dedicating its trips to the reefs of Racha Yai and Racha Noi. Custom built for diving and measuring 40 meters in length with a 10-meter beam, this vessel carries up to 50 guests across 13 cabins, offering aircon seaview cabins, en-suite bathrooms and warm water showers for comfort between dives.
Over four nights and roughly 12 dives — with up to three dives each day — you'll explore some of the region's most popular destinations. Racha Yai offers easy, scenic dives and artificial reef wrecks, while Racha Noi delivers deeper sites shaped by impressive granite formations and wide-open visibility. Clear water and calm seas make these waters ideal for certified divers of all levels, and manta ray sightings are possible during the November–April season.
On board you'll find free Nitrox, a dedicated dive deck and tenders, plus a camera room with separate rinse for underwater gear. A sun deck, observation deck, air-conditioned saloon, kayaks and daily housekeeping round out life aboard, with PADI training available for those looking to build their skills at sea.
