History

The construction of the
Denis Sullivan was first proposed in 1991 by a group of Milwaukee residents and volunteers from other states. Their plan was to build a tall ship

. Community involvement was welcome in the project, and almost a thousand people donated almost a million volunteer hours toward the
Denis Sullivans construction. Through the efforts of both professional shipwrights and volunteers, the Denis Sullivan was partially completed and launched in June 2000. She departed Milwaukee for her first sail to the Caribbean in November 2000.

Design

The Denis Sullivan is not a replica of a specific vessel. Rather, her design is inspired by that of the Great Lakes cargo

In designing the Denis Sullivan, architects Timothy Graul Marine Services looked to several nineteenth century Great Lakes schooners for inspiration, including the Rouse Simmons
