My I suggest "the Gentleman's Guide to Passages South" by Bruce Vansants. I have read it but have never used it for voaging, yet!!
The information seems usefull. While most bash to windward day after day, Vansants has suggestions for using fronts and land effects to ease the pain as well as suggestions for the best anchorages. He also gives advice about which
charts are the most reliable.
About $30
