Sailing Vessel Denis Sullivan is the world’s only re-creation of a 19th century Great Lakes schooner and a floating classroom for water education programs. The S/V Denis Sullivan serves as a Great Lakes ambassador, enhancing awareness of the Lakes and freshwater issues on a large scale as it makes its experiential, educational sails through the Great Lakes region, the east coast, and the Caribbean.
The S/V Denis Sullivan was launched in 2000 and is designated as Wisconsin’s Official Flagship. She has also been recognized by the United Nations as an ambassador of the World’s Freshwater concerns and for a true commitment to freshwater education on World Environment Day 2007.
As an educational platform, S/V Denis Sullivan educators facilitate inquiry-based programming, such as Lake Watch Expeditions and Science Under Sail programs connect learners of all ages to the Great Lakes through the observation and investigation of this great freshwater environment.
Mission Statement: "To provide programming that is an introduction to field science with an emphasis on environmental issues, Great Lakes concerns and stewardship of our natural world."
The S/V Denis Sullivan is a re-creation of a typical 19th century 3-masted Great Lakes schooner. Her triangular sail on the upper foremast—the raffee—is a sail unique to Great Lakes schooners of the time. Schooners like the S/V Denis Sullvian were the common vessels on the Great Lakes from 1833 to the 1890s.
The S/V Denis Sullivan's design was inspired by and based on five Great Lake schooners from the late 19th century: Moonlight, Rouse Simmons, Lucia A. Simpson, Clipper City and Challenge.
The ship is named after Captain Denis Sullivan, the owner and captain of the Moonlight in 1874.The Moonlight was said to the "Queen of the Lakes" because of the vessel's reputation of being the fastest and finest cargo vessel on the Great Lakes.
