 Several other vessels were damaged or ran aground trying to escape the storm's fury.Overall estimates state 59 sailors were lost in what would be the worst maritime disaster on the Great Lakes since the Great Storm of 1913.Early in 2015, Michigan Shipwreck Research Association, a 501(c)3 non-profit based in Holland, Michigan, announced the results of a 2014 survey of the wreck which revealed the cause of the "William B. Davock"s loss was a broken rudder, which jammed against the propeller breaking off one or more blades, rendering the vessel without steering or propulsion.
