Thanks for showing interest with this little but necessary fix for Ferrol.
The port is in the same place as it was 75 years back. You can google-earth it and see for yourself, and even someone with more knowledge than me can fine-tune the place.
And for Alvaro... you can download this (in Spanish). I uploaded it some weeks ago. I think you'll enjoy this a lot.
