Denis Sullivan


USCG Certification

Sailing School Vessel (Subchapter R), Passenger Vessel (Subchapter T)


The S/V Denis Sullivan, owned and operated by Discovery World Ltd., was completed by over 900 volunteers and launched in 2000. This replica of a Great Lakes freight schooner, and Flagship of Wisconsin, operates as a floating classroom and goodwill ambassador for the state. From her homeport of Milwaukee on Lake Michigan, the schooner offers educational sails, public day sail and private charters for people of all ages from May through September and is committed to re-establishing the historical, cultural, and environmental bonds between the community and one of its most valuable resources, the Great Lakes. The educational programs available are a 90 minute Dockside Discovery, two to three hour Lake Watch Expeditions and two to fourteen day Science Under Sail. She also offers a “Bucket List Sail,” a multiple day voyage throughout the Great Lakes for the adventure-seeking adult.
