The Lottie Cooper, a Great Lakes schooner built in 1876 by the Rand and Burger Shipyard of Manitowoc, Wisconsin, was named for the daughter of one of its original owners. The vessel was 131 feet long, 27 feet wide, nine feet in depth of hold, and measured 250 gross tons. It capsized off Sheboygan during a fierce gale on April 9, 1894. Much of its original structure was salvaged on September 1, 1992, during construction of the Harbor Centre Marina, including an 89-foot-long center section believed to be the largest section of a Great Lakes schooner on public exhibit. The vessel represented the historic period when thousands of commercial wooden sail and steam vessels worked the dangerous waters of the Great Lakes.
