Site details

The Regina is a 250-ft steel package freighter lost with all hands in the Great Storm of November 1913 and not located until 1986. She lies upside down off Port Sanilac in the Sanilac Shores Underwater Preserve in about 80 ft of Lake Huron, with the hull bottom reached at roughly 25 ft. A 56-ft opening in the hull allows qualified wreck divers into the hold, and scattered cargo still litters the lake floor around her.
