|Located 11 miles southeast of Manitowoc, Wisconsin, the Floretta wreck site (47-MN-0394) lies in 180 feet of water in Lake Michigan. Constructed in 1867 and lost in 1885, Floretta represents a vessel class, the canaller, which traveled the longest routes of any of the Great Lakes vessels while carrying Midwestern grain to eastern markets. Little historical documentation exists on canaller construction and operation. Much of our understanding of this vessel type has come from archaeological data recovered from wreck sites like the Floretta. The Floretta meets the registration requirements for Criteria D at the state level as a good example of the sailing vessel property type and for its role in the grain and ore trade as described in the Multiple Property Documentation Great Lakes Shipwrecks of Wisconsin (Cooper and Kriesa 1992). The Floretta was discovered in 1980 and documented by the Wisconsin Historical Society in 2013. Due to its remote location and extreme depth, the Floretta remains lightly visited by divers. The Floretta site has produced a wealth of archaeological knowledge on canal schooner construction and use, and it will continue to produce important archaeological data in future years.
