Overview
Phuket is the undisputed yachting capital of Thailand and Southeast Asia. The island has several full-service marinas, all within easy reach of the international airport, making it the natural base for an Andaman charter.
Yacht Haven Marina
Yacht Haven, on Phuket's northern tip, is the largest and best-equipped marina, with deep-water berths, a haul-out yard, fuel, and provisioning. It's the main bareboat charter base and a popular long-stay marina for cruisers.

Ao Po Grand Marina
Ao Po Grand Marina, on the east coast, offers the closest access to Phang Nga Bay's limestone karsts. It's a premium marina with excellent facilities and a popular departure point for the bay's signature scenery.
Krabi & beyond
Krabi, on the mainland east of Phuket, provides an alternative base closer to the Phi Phi Islands and the eastern Andaman. Facilities are more modest but improving, and the position suits one-way or eastern itineraries.
