During this trip I traveled with my business partner and his wife from Shanghai to Hong Kong to Phuket. From Phuket we sailed south towards Phi Phi, with a few days spent at different anchorages in between Yacht Haven Marina and Phi Phi.
During this trip we anchored at a number of locations including:
Koh Yao Yai @ The Paradise Resort
Koh Phi Phi @ north east bay
Koh Yao Yai @ a bay just south of Paradise Resort
Koh Phanak @ a spot on the south east
During the southwest monsoon season all these anchorages are on eastern shores to avoid wind and waves. We avoided those things at all anchorages except on Koh Phanak, where the swell still managed to wrap around the southern end of the island.
Several nights were spent at the anchorage on Phi Phi, where we used long tails to access nearby snorkeling sites and to make a 'grocery run' to Tong Sai bay.
