Koh Racha Yai sits roughly 20 kilometres south of Phuket, and reaching it aboard the Discovery makes the journey every bit as rewarding as the destination itself. This 47-foot Power Catamaran, built by Stealth - Asia Catamarans, carries up to 30 passengers in genuine comfort — the kind of space that lets you breathe, move around, and actually enjoy being on the water.
The Racha Yai (4h) half-day tour is a straightforward, honest proposition: a well-regarded island known for its clear water and relaxed atmosphere, reached on a capable, purpose-built vessel. There are no inflated promises here, just a reliable route to one of the more appealing spots within Phuket's wider island chain.
The Discovery's catamaran hull keeps the ride stable and comfortable, which matters when you want to arrive at Koh Racha Yai feeling fresh rather than rattled. With capacity for 30 guests, the boat never feels overcrowded, and the Stealth - Asia Catamarans build quality is evident throughout. For anyone based in Phuket looking for a well-organised half-day on the water, this route on this particular yacht is a considered choice.
