About THE STRAITS OF MACKINAC
The Straits of Mackinac is a purpose-sunk Lake Michigan ferry wreck off Chicago that gives divers a clean, easy-to-read freshwater profile. It sits upright on sand and muck, with enough relief to make the bow, mast, and deck layout easy to follow on a charter run from the city. Cold water, variable visibility, and the open-lake setting make it a better fit for intermediate divers in the main season.
