Site details

Built in 1903 as the excursion steamer Chequamegon and converted to a tug, the Robert C. Pringle sank without loss of life off Sheboygan in 1922 after striking floating debris. Discovered by Steve Radovan in 2008, she sits upright and remarkably intact in about 300 feet of water — pilothouse with glass still in its windows, wheel, bell and searchlight all in place. This is one of Wisconsin's premier extreme-depth technical wreck dives, reserved for experienced trimix/CCR teams.
