Ferries operated by Norden-Frisia AG have been serving the East Frisian island of Norderney for many decades. Navigation in these coastal waters poses special challenges: in some areas the waterway only leaves a few centimeters below the keel and the water contains a significant amount of swirled-up sand. A new sister ship of the double-ended ferry MS Frisia IV equipped with Voith Schneider Propellers (VSP) is to enter service in summer 2015. The shipping company again chose Voith Schneider Propellers as these are ideally suited for the specific operating conditions in shallow tidelands.
