Thanks,I had already tried those two. They say they don't have annual places
I guess that with so many little arbors and so many sheltered places it will be possible to find a less expensive berth but probably those places don't have internet sites and should be really hard to find
I have find already some places with berths, but they are not what I call at a good price
Regarding prices in Corsica and Sardinia they are about the same but I could find a shipyard on Sardinia where I could let my 36ft boat for 2500€/year (secured) and this seems quite impossible to get in Croatia.
