The Vessel and Her Loss
Originally the Macassa, built in Scotland in 1888 for Hamilton-to-Toronto passenger service, the ship was rebuilt and renamed Manasoo in the 1920s for the Owen Sound Transportation Company. In September 1928 she left Manitoulin Island loaded with cattle and began listing in a storm, rolling over off Griffith Island. Sixteen of 21 aboard died. The wreck was not found until 2018.
