Vessel History

History  The Davidson Shipyards were notable because they continued building large wooden vessels after most yards converted to steel hulls.  They did it by using new construction techniques of using steel and iron to reinforce their wooden hulls.  The Pretoria is an example of their construction techniques. 
Disposition Sank on September 2, 1905 off Outer Island, Apostle Islands, Lake Superior in a storm killing five crew.  It was under tow of the steamer Venezuela.

In 2005 GLSPS partnered with WHS to put back the boiler which was used to drive the steam powered windlass.  The boiler had been removed back in the 1960’s for salvage and sat for forty years in the back yard of Ed Erickson who was Bayfield’s mayor for a time.
