Greek ferryspotting is in my mind an underrated sport. If you are like me this is something you can enjoy even at home. Take your favorite webcam overlooking a Greek port (more interesting to select a busy one…), let us say Parikia (Paros), and also fire up Live Ships Map – AIS – Vessel Traffic and Positions (select Mediterranean/Aegean South, and deselect uninteresting boats to concentrate on the ferries) from MarineTraffic.com and you are all set. Happy hunting!
