Freighter View Farms | Chris Izworski

There is a name for the people who track the freighters, who stand on breakwalls and bridges with binoculars and notebooks and know the vessels by their hull colors and stack markings before they are close enough to read the name. They are called boatnerd. This is not an insult — it is a title, worn without apology, and the community that has gathered around it has produced one of the more quietly remarkable websites on the internet: boatnerd.com, where the movement of every commercial vessel on the Great Lakes is tracked, photographed, and logged in a rolling record that is part shipping database and part love letter to steel on water. I check it most mornings before I check the weather.

The Saginaw River meets the bay just south of where I live. From certain spots along the shore you can watch a vessel make the turn from the open bay into the river channel — that long, slow arc that a 700-foot self-unloader makes as it comes around the breakwater at the river mouth, moving at a walking pace but generating a presence that fills the whole frame of the view. Bay City sits along the river’s lower reach, and the ships that call here — carrying coal, salt, limestone, occasionally grain — pass through the heart of town on their way upriver to the terminals at Saginaw. They are close enough, in places, to read the lettering on the hull without optics.

The Fleet and Its Rhythms

The Great Lakes fleet has names that deserve to be read aloud. The Paul R. Tregurtha, at 1,013 feet the longest vessel on the Lakes, running iron ore from Two Harbors to the steel mills at Burns Harbor. The Kaye E. Barker, an older straight-decker that has been on this water since 1952 and carries herself with the patience of something that has outlasted everyone who expected her to be retired by now. The American Spirit. The Indiana Harbor. The Edwin H. Gott with her distinctive blue hull and the laker’s characteristic silhouette — pilothouse forward, engine room aft, the long flat cargo hold between, designed for a body of water that has specific requirements and no particular interest in what the ocean does.

Not all of these pass Saginaw Bay. Some are iron ore boats that run the Superior-Huron corridor and never turn south into Saginaw Bay at all. But the vessels that call at Bay City and the upriver terminals are the ones I know best — the salt boats especially, because the Detroit Salt Company terminal in Bay City is a regular stop, and a vessel loading salt sits at the dock for a day or two, long enough that you can watch her settle deeper into the water as the holds fill, a slow descent of six or eight inches that is somehow more impressive than any faster movement could be.

Boatnerd and the Practice of Paying Attention

Boatnerd.com shows vessel positions updated in near-real time from AIS transponder data — the same system that commercial vessels use for collision avoidance. You can pull up a chart of the Great Lakes and watch the icons moving, slow as hour hands, each one a ship with a name and a cargo and a history. Click on any vessel and you get its current speed, heading, last port, next destination, and often a gallery of photographs contributed by people who were standing on a breakwall somewhere when it passed.

The practice this generates is a particular kind of attention. On a clear morning in October, when the bay is going dark blue and the light is that low-angle autumn gold, I might check boatnerd, find that the Hon. James L. Oberstar is inbound from Lake Superior, estimate her arrival at the river mouth, and be on the shore with coffee when she comes around the breakwater. This is not a hobby that requires explanation to another person who lives on the water. To anyone else, it requires all the explanation in the world, and I have largely stopped trying.

The Ships and the Garden

There is something the freighters and the garden have in common that I did not understand for a long time. Both operate on a schedule that ignores your preferences. The corn harvest does not wait for a convenient weekend. The Paul R. Tregurtha does not pass Saginaw Bay at an hour that suits your schedule. You either pay attention when the thing is happening, or you miss it. This sounds obvious. Most of the things that are true about gardening sound obvious until you have spent a decade learning them with your hands.

The season for the boats runs roughly the same calendar as the garden — opening in late March or early April when the ice in the connecting channels has cleared enough for the Coast Guard to open the Soo Locks, closing in January when the weather makes the upper lakes dangerous and the ore docks have had their fill. In between, the fleet moves continuously, and the river at Bay City is a thread in that movement — one of the points where you can stand on the bank and feel the scale of what the Great Lakes are: not a scenic backdrop but a working system, two hundred years of industry on water that was old long before the industry arrived.

This blog is named for the view. The freighters are not incidental to it — they are part of what this place is, the same way the bay moderating our frosts is part of what the garden is. When I am standing at the edge of the raised beds in the evening with the light going off the water, and one of those long steel hulls is moving along the horizon, the two things — the garden and the ship — seem less like different subjects than like the same subject seen from different angles. A place. The things that belong to it. The attention you bring.

If you track the boats and want to compare notes on which vessels call at Bay City, or if you have a favorite stretch of shore for watching the fleet, I would be glad to hear about it. And if you have not yet spent an October morning with boatnerd open on your phone and a coffee in your hand waiting for a freighter to make the turn at the river mouth — it is worth the effort of arranging it at least once. The Great Lakes maritime history reference at chrisizworski.com has context on the commercial shipping history of the basin. And the Saginaw Bay ecology reference covers the natural side of the same water. The bay holds both.

The same waters the fleet navigates have a longer history beneath them. The Great Lakes shipwrecks reference and the lighthouse guide at chrisizworski.com cover what came before the AIS transponders — the wrecks and the lights that tried to prevent them.
