"The S/V Denis Sullivan is a 137-foot, three-masted recreation of a 19th century Great Lakes cargo schooner that was completed in 2000 by Pier Wisconsin, formerly the Wisconsin Lake Schooner Education Association. The S/V Denis Sullivan is the flagship of Wisconsin with its home port in Milwaukee. Although rigged traditionally, the Denis Sullivan is a modern educational sailing ship, complemented with two 180hp diesel engines, a scientific laboratory, and modern communications and navigation equipment."  Quote from the Pier Wisconsin web site.
