The waters are clear aquamarine to deep indigo. The winds blow steady during the winter monsoons, when the skies are brilliant blue. The islands offer pristine, protected anchorages, fringed by ivory white beaches and capped by thick rain forest. This is why Koh Chang, Thailand’s second largest island located off the Trat coast and the archipelago that forms Koh Chang National Marine Park offer some of the best sailing in the Thai Gulf. Both single hull and catamarans are available for charter. Lengths range from 32ft. to 56 ft. and are all fully equipped. There are also sailing schools where you can learn or brush up on your sailing and navigation skills.
