not a Mississippi steamer
« on: March 17, 2023, 06:04:30 PM »
Today a ship came by, which has adjusted to the constant low water of the Elbe. But it's high tide at the moment.

Very modern ship, but definitely still a sternwheeler, quite an interesting design! The sternwheel design is not common in Europe, is it? Mostly sidewheel that I have seen before.

There were also ships with stern wheel drive on the Elbe. Earlier with steam and later with diesel engine.
But they were rare.
I suspect the new ship not only with the stern wheel drive. The blades are rigidly mounted. They do not dive vertically into the water. It kind of looks like it.

Looks very strange to me - almost like the water is turning the Wheels and not the other way around, where the wheels are moving the water (= moving the ship in the water) ....
You can also see that the wheels are lifting the water up to a substancial height .... + I agree with Michael that they are a strange shape for propulsion ....

Or put in another way - I'm wondering if the Wheels aren't there just as Show Pieces and Not Propulsion ....

Very possible that it  uses either  props or a jet drive below and in front of the  wheels.

I hope that google translates it but there are only the two rear wheel drives.
Perhaps the engineers forgot that adjustable blades existed more than 100 years ago.

A loooooong low vessel. Cool looking. Why the radar bow and stern?

Thank you for the link Michael - it is interesting.

It tell us that there are more propulsions onboard - but they can usually only stear and do not really add to forward or reverse.

A more strange thing is that it states that it was build with the fixed Paddles we see in Michaels video from yesterday - but that they have been upgraded to the Excenter driven type we see on all the old Steam-Paddlers  ....
So did somebody 'Downgrade them during the Winter'  :???: and why go back to the less Effecient design of non-moving blades  :headscratch:

Impressive low Draught on this Hull Design  :praise2:

Radars - I see that they are down to Roof level (most likely to clear low bridges in Hamburg) -> resulting in a 180-200 degree view from each Radar Antenna -> combined 360 view.

As a possible reason, rigid wheels can be built stronger... maybe an advantage where light groundings are expected, or where heavy flotsam is a problem.

The ship has a radar fore and aft. That should be better for the narrow river.

it looks like the blades are movable. And it should be the main drive. In front there are two powerful moveable bow thrusters.

Those look much more efficient, the blades will change angle to keep them pushing vertically as they rotate.  The picture from the Wikipedia page is from 2016, these must be the better ones the installed after that. Would make a good model!   :stickpoke:

oh Chris, I already have so many projects in mind.
Build a steamboat with a paddle wheel, very challenging!
I looked through old pictures, there were steamers with a tail wheel in my city about 100 years ago. And also the steamers with 2 rear wheels. All workhorses. A steamer has been moored in the city center on land since 1974. Was pulled ashore immediately after the last trip by Russian armored recovery vehicles and a restaurant set up there. Incidentally, there is also the steering machine on deck, a completely different design, and the anchor winch. I also believe the steam winch to lower the chimney.

Your picture in post #11 is exactly what I expected the update to be - but I can't see that being the same Wheel in the Video ....
The blades in the Picture are always in a Horizontal position - but the ones in the Video are Not  :noidea:

No matter - we are not here to solve that question - and the Ship + Propulsion is nice to look anyway  :cheers:
