Today’s post comes from  Steve Grooms

When I was a boy the most romantic and impressive form of transportation was the train. I grew up listening to the lonely nighttime screams of passing trains. A kid in my school was so involved with trains that he memorized data on all the train travel in Iowa. You could ask him any kind of question about trains. He’d barely pause before reciting details of train schedules.

I’ve never had that kind of mind. I’m a “big picture” guy, not a detail guy, someone more attuned to forests than to individual trees.

The closest I ever came to developing an esoteric interest was when I fell in love with a hand-carved carousel built a century ago. I was smitten to the point of reading a lot of background knowledge about carousels. It is a topic I can talk about at length. But in the end, I could not work up enough interest to become an expert about all the various makers of carousels in the country. A true lover of carousels would be fascinated by obscure little carousels that just look garish and cheap to me. My deepest affections were for one splendid carousel, not the whole category.

This comes to mind because my daughter is in the early stage of becoming immersed in a new interest for our family: ship watching. My son-in-law grew up in a lovely old home on the US bank of the St. Clair River. The St. Clair is deep enough to host the biggest ships sailing the Great Lakes. The river is, in fact, the only connection between the upper lakes (Superior and Michigan) and lower lakes. Any ship traveling far in the Great Lakes must pass close to John’s home, “close” meaning about a hundred yards. Now that our family lives in Port Huron, Molly has become fascinated with the ships we see here.

The photo heading this column is one I took in late September. The ship is the Federal Seto, a particularly lengthy “saltie.” It is owned by a shipping company based in Montreal. Since I took its portrait the Federal Seto steamed through Lake St. Clair, passed through Lake Erie, and then through Lake Ontario. After running the length of the St. Lawrence Seaway, today the ship has just entered the Atlantic Ocean on its way Rouen, France.

The major distinction between different bulk freighters on the Great Lakes is between “salties” and “lakers.” Salties are shorter than lakers and have higher sides. They move freely from lake to lake but also across oceans. Lakers, many of which are about a thousand feet long, cannot fit in the locks that connect the Atlantic Ocean with the Great Lakes. They work hard but always within the Great Lakes. In addition to being shorter and taller than lakers, salties are younger. The salty water of oceans is extremely corrosive, so salties rarely live longer than 20 years. By contrast, because lakers are not subjected to all that salt they can live many decades, even longer than a century.

Ship watching is popular hobby in this area, and there are many resources. Web sites track the movements of these ships. Many museums educate visitors about the shipping trade. There are books on ship watching, and newsletters. If you want to know the precise location and sailing plans for individual ships, “there is an app” for that. There are, in fact, several apps for smart phones that track these majestic ships at all times.

I was surprised by my daughter’s surge of interest in shipping. She has always had an active mind, but this is the first time she has immersed herself in a topic like this. Molly knows a great deal about Great Lakes ship traffic. She has favorite boats that she tracks with interest. She is highly excited by the fact a new ship being built in Europe will soon join the fleets of freighters already working the Great Lakes, and she will be sure to be on the porch of her mother-in-law’s home the first time it travels the St. Clair River.

Have you ever developed a fascination with an esoteric topic?
