Shipping company Römermann
Since 1972 there has been the only passenger boat service in the Harz on the Okertalsperre. At that time, it was operated by the local public transport company KVG Braunschweig, and in 1976 it was taken over by the spa operating company "Die 5 Oberharzer". In 1983, Captain Hermann Römermann, formerly on great voyages, bought the shipping company and founded the shipping company Okersee Schiffahrt GmbH, or OSS for short.
Known as the "Oberharzer Gebirgsmarine", the Römermann family now operates in the second generation after son Captain Michael Jonas Römermann took over in 1994. The business continued to grow, so the desire for larger capacities soon arose. The OSS went in search of a new ship. The former "Sauerland" from the Biggesee in Sauerland was the right ship and has now been sailing on the Okertalsperre under its new name MS "AquaMarin" since March 2001.
