In 1847 Captain Joseph Edwards built the schooner Citizen here, beginning a maritime tradition in Manitowoc that has never ended. One of the shipyards along the river banks built the Challenge, believed to be one of the first clipper ships produced on the Great Lakes. The Cora A., launched here in 1889, was the last schooner built on the Great Lakes. During the late 1800s, the Goodrich Transportation Company played an important role in Manitowoc's growth, as its passenger steamers brought people and goods to docks east and west of this point. As the smaller shipyards disappeared, the Manitowoc Shipbuilding Company grew and prospered, building 437 hulls in Manitowoc, including 28 submarines during World War II. By 1978 the Burger Boat Company was the only shipyard left in Manitowoc.
