Henry C. Grebe & Company, Chicago IL
Henry Grebe opened his yachtbuilding yard in 1921 on a site previously occupied by Great Lakes Boatbuilding: it closed in the 1960s. It was located on the North Branch of the Chicago River, just northwest of the West Belmont Avenue Bridge: the site is now occupied by the Belmont River Club townhouse complex. Little more is known about this yard, however, and if anyone can provide any information about either the yard or the ships it built, please e-mail it to me at tim@coltoncompany.com.
