Phuket has a genuine yacht-basing and marina scene, mainly concentrated on the island's calmer east coast.
Ao Po Grand Marina
Located on the north-east coast, one of the island's main full-service marinas, offering berthing, fuel and maintenance services for private and charter yachts.
Boat Lagoon
A large marina and boatyard complex also on the east coast, combining berthing with boat sales, repair and storage services — one of the region's bigger marine service hubs.
Why yachts base on the east coast
The east coast faces the calmer waters of Phang Nga Bay rather than the open Andaman Sea swell hitting the west coast — a more sheltered, practical location for long-term berthing than anywhere on the tourist-facing beaches.
Relevance for most visitors
Mainly relevant to yacht owners, charter operators and anyone specifically looking into private yacht charters — not a typical sightseeing stop for the average visitor.
