I have the 2015 edition. Most cruising resources list Pavlidis' book and associated charts as the best reference for sailors cruising the Ts&Cs. There is a lot of information here, though I'm a little stumped by the organization of the book. The best thing, I think, if you are using this to plan a sailing adventure there is to read this while looking at a small scale chart of the islands, because flipping back and forth trying to find locations referenced in the book is difficult and distracting. Also, if you're going to be sailing there, invest in Van Sant's book, Passages South, for the additional detail it offers.
