The Huron, the last lightship on the Great Lakes

History and culture

A lightship is exactly what it sounds like: a lighthouse you can’t build, so you anchor a boat there instead and put the light up its mast. Where the water is too deep or the bottom too soft for a tower, a crew rides out a permanently moored vessel through every storm the lake can throw, holding station so other ships know where the danger is. The Huron did that job off Port Huron for decades, and she was the very last of her kind on the Great Lakes.

Launched in 1920, Lightship No. 103 spent her first years on Lake Michigan before moving in 1935 to Corsica Shoals, a treacherous sandy patch about six miles north of Port Huron. For roughly thirty-five years she sat out there marking the edge of the dredged channel that funnels lake traffic down into the St. Clair River — one of the busiest pinch points in the whole Great Lakes system. Her crew lived aboard a ship that, by design, went nowhere; they rode out the gales at anchor precisely so the freighters wouldn’t have to guess.

In 1970 her anchor came up for the last time, and with it the lightship era on the Lakes ended — radio beacons and lighted buoys had finally made the floating light stations unnecessary. She’s the only Great Lakes lightship left, and one of the only survivors of her whole 1918–1920 building era. The federal government recognized her as a National Historic Landmark in 1989.

Now she rests at Pine Grove Park, painted her old working black-and-white with HURON in tall letters down the hull, open to walk through from spring into fall. Climb down into her quarters and you stand where men spent long anchored months staring at the same stretch of water, keeping a light burning so the giants in the channel could find their way home.
