It 's worth buying the recently published Seventh Edition of the RCC Pilotage Foundation "Atlantic Spain and Portugal" if you are cruising in this part of the world. Clearly illustrated and bang up-to-date.
In addition to OCC negotiated discounts it is possible to buy a "Pasaporte" which gives berthing discounts of 15% in several marinas in the area. Cost: €5. Amazing value.

Alex and I spent two months cruising in Galicia this past summer and returned for another week in October. Aleria is now overwintering in Punta Lagoa. I have written about our experience extensively in my blog with an overview here and links to individual pages for each of the Rias. The November 2017 issue of Yachting World also has an article I wrote about our experience. Feel free to contact me with questions.
