Dumb question.. I presume they lost rudder authority as well..

if they had been able to just restore rudder control and focus on steering through the bridge without main power- could this have stood a chance?
Without the main engine running, at the speed the ship was moving there wouldn't be sufficient water flow over the rudder for it to be effective.

It's only for barge/coastal craft drawing less than 10', better than nothing and the US uses a lot of fking huge barges to shift stuff about which aren't really a thing in the UK or even europe.
I can't see it taking them long to get it fully open for shipping - although the "massive" crane they brought in doesn't look particularly impressive.

Barges running all sorts of freight through Europe - Germany and Holland for example, on Rhine.

O/T As a kid, I remember waiting for boat to come fetch me from the middle of the Mississipi in Iowa, after being thrown from the rubber donut it was towing through the wake waves, and watching this train of huge barges heading downstream toward me. No idea how big barges get further downstream.

A large european barge might be 2000 tonnes, US supersize 20000 tonnes and as you note they also tie lots of them together, which does happen in europe but in twos or fours rather than a dozen or occasionally more. Barge traffic can get as far north up the Mississippi as Minneapolis and down as far as the sea.

Was it the beer that affected your spelling of "paddlewheel"?

As another civvy boater, I have also always known it as prop walk.

Transverse thrust is the term used in Pilotage and in the Merchant Navy.

Every day is a school day, learn something every day, spelling I blame the festering iPad keys, when one is used to touch typing on a proper keyboard.

Just to say the paddle wheel effect is a navy term just as we say port and starboard and some civvies will say left and right, but I have googled prop walk and it’s very informative, so thanks for the term, one for my little grey cells.

But our term is right, so their term must be wrong.

Have you learned nothing in your 198 months here?

I saw that after posting, but couldn't be arsed editing.

Anyway, I was trying to help elevate HTE to the 200 month club ahead of time.


ps My earlier comment re beer was supposed to be a riff on the beer icon ending the post I quoted. Sorry if it offended anyone.
