Let the river decide the speed

Great morning. Got to the bottom of my coffee cup without finding a bug.

Geography Lesson

The St. Clair River flows south from Lake Huron into Lake St Clair. The Detroit River flows south from Lake St Clair into Lake Erie. We are ran up river, both the Detroit River and the St Clair River, all day today. The current was quite strong on both rivers evidenced by a 4 foot elevation rise over ~27 statue miles.

One thing about rivers, its best to let them decide your travel speed. 1500 – 1600 rpms is the sweet spot for yes dear’s… 2-250 Hino engines. At times the rivers today let us run 6.5 kts and other times we ran 3.4 kts, both much slower than our 7.5 rpms – 8 rpms average. In the sweet spot increasing rpms only burns fuel and doesn’t do much to increase speed.

Along the Way

US Steel as far as the eye can see. Iron ore, old plants and new plants.

The south side of Detroit is industrial. Auto manufacturing related plants of various kinds go on and on. The Canadian side isn’t any prettier.

There is a different configuration of tow boat / barge in this area than we’ve seen before. When they are joined they resemble a ship with a swap out bridge/engines. The barges are notched so that the tow slips partially into them. It must be more efficient/cost effective to switch a tow out if mechanical issues arise.
I don’t know what the configuration is called 🙁

Heading into Detroit

Time trials for the Detroit Grand Prix were happening on Belle Isle as we passed by.

Here they come.

Lake St Clair

Nemesis of the Day – NONE. Today there were almost 50 dragonflies on yes dear…. Flies hate dragonflies. Dragonflies eat flies 🙂

The southern end of the St Clair River has cottages on the USA side and open land on the Canadian side. As we headed up the St Clair River the Canadian side became more residential.

The northern end of St Clair River is industrial, little bit more on the Canadian side that the USA side. All of the quaint houses on the USA side of the St Clair River have a most excellent view of Canadian factories and plants.

Remember the Waterworld post-apocalyptic action film staring Kevin Costner? The St Clair River felt that way.

I’m really glad this is not a weekend day. Pleasure boat traffic must be a nightmare. I didn’t take any pictures of Donzi boats (cigarette boats) as I refuse to feed their egos. If I had a dime for every Donzi we saw screaming past I’d own the Queen Mary.

Port Huron

My camera went to bed early, even before yes dear… was docked.
