Thirteen men and eleven head of cattle died in this accident, making the sinking of the "Ludwig" by the "Stadt Zürich" the most serious shipping accident known at that time that had happened on Lake Constance.

Another theory regarding the purpose of these holes suggests that “ropes for holding oars were threaded through these holes.” Ship
