I'm planning a trip there in September and was looking into the possibility of a bareboat charter. Has anyone been there and can offer a little beta, specifically for the Railay area? Is there any certification requirement in that part of the world? What is the navigation and anchoring like? I've got lot's of small keelboat experience as well as a couple of weeks charters on the chesapeake, and will have a few others in my group with the same experience. Should I be intimidated by this area and want a skipper, or is it pretty mellow? Thanks in advance for the help.
