The best cruising guide we found is Frank Virginito's free "A Cruising Guide to Puerto Rico." He continues to update the guide. The Street guide is badly out of date and the Pavlidas guide has GPS coordinate errors and other errors.

You can read about our experiences from our 2015 cruise at http://dinghylife.wordpress.com/2015/11/18/seabbatical-trip-report-october-16-november-15-2015/

Our last visit to Culebra was July 2017. Wonderful place with wonderful people.
