Ok then ... it looks like I'm the first off the mark although I'm sure there are many better qualified than me to comment.
Phuket is a large island with several marinas
and anchorage fields around the island and nearby region. It is probably SE Asias largest and most popular domestic cruising and charter
yachting is big business with (I'm guessing a bit) a couple of hundred yachts available. Customers are predominately European and Australian. While long term expat liveaboards and a domestic Thai boating
community is several times bigger.
It is also a popular stopping, resting, refitting location for international cruisers and circumnavigators from budget
cruisers to superyachts. It has something to offer everyone irrespective of lifestyle or class.
The yacht service
industry is large, well equipped and diverse with a skilled but relatively low cost workforce making it a popular location for boats requiring major refitting or just budget
The cruising waters around Phuket offer over a hundred islands from spectacular limestone Karst towers and mangrove wetlands to coral
fringed sand cays. You can anchor
off a 5 star resort, go ashore and treat yourself to an international cuisine or off an isolated fishing
village and sample seafood just minutes out of the water
Some islands and attractions are tourist hotspots which have literally thousands of visitors arrive in hundreds of boats daily; while others are unspoilt natural wonderlands where you can anchor
in glorious isolation. You can go for a daycruise and be back at your anchorage in the evening or go sailing for a month and never touch land.
A mix blessing is the hotch potch of rules and regulations
. There are the usual international requirements for visas and immigration conditions and then there is the largely unregulated and often ignored navigation
conditions once you have entered the country. Rampant tourism and the Thai penchant for ignoring navigation
rules anyway draw a lot of criticism.
While Phuket Island is where the main marinas
are based there are smaller marina developments and cruising facilities in the wider region. Phang Nga, Krabi, Koh Lantra and even farther afield the Similian Islands to the north and Tuataro Islands to the south should be included.
Ive been cruising the region for three years now and I think barely seen a quarter of what the area has to offer.
I hope that helps a bit.
