Großer Hafen

The large harbor adjoins the connecting harbor to the west. On its southern side, it is separated from the Jade Bay by the Fliegerdeich. There are pleasure boat moorings and boatyards in this area. To the southwest, the Grodendamm closes the passage to the former parts of the harbor, which today form Lake Banter. Several companies and the navy's magnetic measuring station are located on the Wiesbadenbrücke bridge to the north. In the central part of the harbor basin are the cable loops belonging to this measuring station for the magnetic measurement and treatment of warships.

The Bontekai, Wilhelmshaven's harbor promenade, stretches along the north side of the Great Harbor. Especially during major events such as the Weekend on the Jade and the Wilhelmshaven Sailing CUP, fascinating traditional sailing ships and other vessels are moored here. In the northwest, north of the Wiesbaden Bridge, the Ems-Jade Canal flows into the ports of Wilhelmshaven. The dike bridge spanning it is the western boundary of the Great Harbour.
