I used local resources when i was there. The tides are like 18 feet in some places. I remember anchoring
1/2 mile off the coast of Rilay and when the tide went out boats where in the mud with no water
under them. Talk with Rob at Yacht haven Marina in Phuket he is the owner of Yacht Pro a sailing school
. He will tell you everything you need to know and provide you with good Thai charts
. Tell him Dan from the U.S. sent you.
