Even though one of my all time favorite watering holes is Happy Island in Clifton it can be a crowded and busy port. Chatham is the anti Clifton. The last time I was there it was more small makeshift beach bars with one major resort. Very non commercial. Good holding and plenty of swing room. As far as Mustique goes, the Life Styles of the Rich & Famous never did much for me. It used to be you paid for a 3 day mandatory mooring even if you were there for only one night.
