I believe there are quite a lot of ferries from southern Spain( Almeria,Motril,Malaga,Algeciras) to Tangier or a couple of ports in northern Morocco.Never been to Morocco myself.I do recall a friend from 35 to 40 years ago (lived near Sleaford? but forgotten his name)who used to do Morocco a lot.If I remember correctly he used to take bits of ladies undergarments down there where they would be made into complete garments for return.He could have been winding me up though.
