Thailand Tourism and Sports Minister Suvit Yodmani said the government will study the feasibility of building a man-made island off the coast of Phuket to provide exclusive mooring for billionaires' yachts.  Suvit said the project would boost Thailand's image as a high-end tourism destination.  Microsoft founder Bill Gates reportedly visited Phuket last month on their 54-meter yacht and told Phuket Governor Niran Kallayanamitr that they would gladly return every year if they had somewhere private to dock their boat.
