The theory was that the cold had been preserving them.
Chuck Letts and Ken Horsburgh both summered in the Les Cheneaux Islands and both owned old wooden boats, and somewhere in the 1970s they worked out why they kept seeing so many others. Lake Huron up here is cold and the season is short. A mahogany runabout that would have rotted out in forty years somewhere warmer had been spending nine months a year in a boathouse, out of the sun, in a climate that does not encourage anything to break down quickly. Their guess was that this handful of channels held more boats from the early 1900s through the thirties still in regular use than anywhere else.
It is the kind of theory you can test by asking everyone to bring their boat to the same dock on the same day.
They took the idea to the Les Cheneaux Chamber of Commerce, talked thirty volunteers into helping, and in 1978 the first show happened in Hessel, a town you can walk across in about ten minutes. The theory held. It has been held every August since.
The setting does a lot of the work. Les Cheneaux means “the channels,” and the name is exact: 36 islands sitting close along the north shore of Lake Huron, with sheltered water running between them. That shelter is why the boats are here in the first place. This is water you can run a low-freeboard varnished hull through without taking the lake over the bow, in a part of the Great Lakes where that is not always true, and the islands filled up with summer families and boathouses on exactly that basis.
The show is now roughly 150 antique and classic boats and more than 300 volunteers, which in a town the size of Hessel means a substantial fraction of everybody. It is run by the Les Cheneaux Historical Association, which has had it for over thirty years, and it draws visitors from across the country for a single weekend in the second week of August.
The boats themselves are the argument. Chris-Craft, Century, plus the ones with no badge left on them at all, mostly varnished, mostly running, many of them owned by the same families for generations. There is a particular thing that happens with a wooden boat that has stayed in one place: it accumulates a record. It gets repaired rather than replaced, and the repairs are visible, and the person at the dock can tell you which of them their grandfather did.
The local history runs deeper than the show. E.J. Mertaugh Boat Works in Hessel, at the eastern end of the show, was the first Chris-Craft dealership anywhere outside Algonac, Michigan, where the company was founded. That is not a small footnote. It means this stretch of shoreline was buying serious wooden boats early enough to matter to the industry, which is the underlying reason there were so many old ones left to photograph in 1978.
What has kept it from turning into a car show on water is that the boats mostly still work. They arrive under their own power. They leave the same way. A festival built on objects that are used is a different thing from one built on objects that are displayed, and the difference shows up in how the docks smell, which is gasoline and varnish rather than polish.
It runs in Hessel, second week of August, one weekend, and the town is small enough that the show is the town for those two days.

Verification note: Ledger written 2026-08-16 before scheduling. The draft's builders line was cut to the two sourced for this show (Chris-Craft via the Association's history page; Century via Lakeland Boating on the 48th show). The largest-in-the-country claim is deliberately absent because the organiser claims only 'one of the largest'; the 8,000 to 10,000 visitor figure and the 36-island count are left out of the copy for the same reason.
