ferry to casablanca?
I'll be going for a month long trip to Morocco in March and will be probably taking a ferry from Portsmouth to Bilbao and drive the usual way down. However, I've seen in several maps some ferry lines from Casablanca to Southampton, but can't find anything on the net. Also there should be a ferry from Spanish Santander to Casablanca, but again no mention of it on the net...
Did anybody take those ferries before (that means, if it exists) and where can one buy a ticket for it?
Thanks for any help
