Thanks for the interesting comments. The vessel is to stay at least half a year in port for reparations and modifications.
@ Jean Hémond: They asked me the right to use that older picture of mine for their website. I gave it for free, emphasizing, that this was not including other (newer)photos.
Of course the "Magnus effect" and the technical application in Flettner rotors are public domain, just some special new modifications may be applied for a patent.

Autoroom
the so-called "soot" on the back of the funnel is normal for ships, never mind how slow or quick. Like a car, you go 20 km/h or 100 you pull air behind you, Same effect here, the backdraw pulls in exhaust to the back of the funnel and blackens it over time.

The "rotor-ship": ultra-modern technology from nearly a century ago!

The outside of funnel is blacked by exhaust gas of diesel generator. It seems the speed of E-1 is quite low.

Note 3 rudders.

Jadran, those covers/fences are to separate the flow going on the cylinder & going above it - it increases the overall performance. You might want to Google "Cloudia" rotor ship - she has multiple fences (Thom fences) on rotors.

:-) a very important issue on the Magnus effect:
The wind must come/blow from the SIDE of the ship, so that the resultant force caused by the cylinders is towards FORWARD, moving the ship forward (an aero-dynamics postulate for this phenomena).
The cylinders MUST BE ROTATING to cause this effect.

Hi Captain Ted,
This below was one of my comments on Sept.13,2012 Re: E-SHIP 1

ROTOR SHIP
A rotor ship, or Flettner ship, is a ship designed to use the Magnus effect (elaborated by scientist MAGNUS) for propulsion. To take advantage of this effect, it uses ROTATING vertical cylinders which are POWERED BY ENGINE. The Magnus effect is a force acting on a spinning/rotating body in a moving air-stream, which acts perpendicularly to the direction of the air-stream. German engineer Anton Flettner was the first to build a ship which attempted to tap this force for propulsion.

Anyhow,,,I am really in the black, I think I saw something like that somewhere, but can someone tell how that stuff functions,,if it functions at all !!!,, Please

There is a good reason, but I really do not know why it is done like that !
The rotor (vertical cylinders) COVERS are designed OVERSIZED in diameter i.e. not matching the exact diameter of the cylinder ... to make them function just like a plain cover for the cylinder.

: does any expert on the subject of the *rotor ships* maybe have a satisfactory explanation !?

I can't stand (or shortly saying, hate) cruise ships built from mid-2000s, but I just love unbearably distinctive ships like this!
