History

Gredo, or "Christ" as she was known then, was constructed in 1916 with a completely wooden superstructure. She operated until 1945 by the Meno navigation company as a tug in the river port of Dortmund. She was renamed Gredo in 1946 by the then owner, a name derived from the names of the daughters; Grethel and Dora. Gredo was then operated for many years as a tug by the Mannheim and Karlsruhe navigation company, then in the 1970's she finished her final working days with the Preuss company of Andernach pulling barges. After years of neglect she was bought in 1986 and renovated by the naval shipyard in Bingen. In this period the superstructure was completely replaced in steel. In 2007 a group of international scientists and engineers 'saved' her from demise and transported her to Lake Maggiore in northern Italy. Mistakenly we believed she would steam straight away! After a further five and a half years of hard work and toil she was finally launched in July 2012 and we have been enjoying sailing her on the lake ever since with the goal of steaming to Switzerland some day.
