Lots of good points and advice here already. I definetely second the posts regarding the anchor(s).
There are (again read Reed's) a few places to anchor
in northern Brittany, and due to STRONG tides, the even better visitor's bouys. Perros-Guirec and Primel-Truegastel (sp?) among thos we used while doing the same trip last summer this time. We went non-stop from Falsterbo in s. sweden
to Portsmouth/Isle of White but after that we really took our time and day.sailed along the cost. It's obviously very important to time the tides corectly esp. in the Channel and in S. Brittany too. If you'll choose the Chenal du Four, inside Isle Ouessant I strongly recommend that you discuss the timing with someone with local knowledge. Nice trip in the right conditions.
In Galicia there are plenty of room to anchor
in the Rias, sometimes inside the breakwaters too, but it's all in Reed's.
Along the Portuguesse west coast
, it's not that many places to drop the hook, mainly Porto/Leixoes, Cascais and Silves, once past Cabo San Vicente and on the Algarve there are a few, including some where you can winter on the hook, no charge.
Check our blog sailblogs.com/member/rodeorm and go back to June/July last year to see our route
with positions and comments.
Drop me a PM once you arrive to Algarve, if we are still around we can have a glass together.
