My old computer monitor departed this world last week, so it was time to buy a new one.

Initially I thought I go for two 23

Hello,

in the meantime just a "Alberich-question": Do you think that the upper pressure hull was also coated with rubber tiles? It appears to be consequential to have done this, hardly to believe that the wooden deck absorbed the Asdic-Signals, but would the rubber coat have stand the enormous temperature of the exhaust pipes, for example? Just wondering about that since I followed your outstanding drawings.

Good luck with the new monitor

P.S.: My first post here, I was a "unregistered member" for years.

 The upper pressure hull was coated. Some of the tiles were riveted, so I imagine those were the tiles along the waterline.
 
 I do not know if the exhaust gases were that hot by the time the exit the exhaust piping.
 
 Tore, how hot do you think the exhaust gases were when they hit the sea water?

The exhaustgases would have a temperature of approx. 400 degrees C leaving the engines and I should imagine the would dammage the syntetic rubber at the outlet. Anyhow the exhaustgases made the seawater steaming at the outlet. In case of the original U 995 outletexecution a 2.5-2 mm layer of syntetic rubber would be dammaged I guess.

I just had a second looked at a photo of U-1105, that has style 6 exhaust outlet and the tiles look like they go right to the exhaust outlet; And perhaps over the cover ??? I will post the picture later.

Tore, I through that the Germans used sea water to help cool down exhaust gases after they leave the engines, this is correct?

Simon.
I can`t remember but I don`t think so. If you look at the exhaust pipe, muffler and sparkarrestor there are no seawaterconnections to my knowledge.

Simon.
In order to prevent misunderstanding, by no seacooling water connection I mean direct injection. As we all know from the previous discussions, the exhaust pipes, valves and silencers are of course cooled by the engine sea coolingwater which to a certain degree cools the exhaustgases as well.

Thanks for the information and discussing the upper pressure hull coating.

Snowman and Tore: I think my thoughts about the exhaust temperatures were inartfully expressed (sorry my fault). I meant the temperature fluctuations which the tiles and mainly the adhesive had to endure along the exhaust pipes.

Snowman: Do you have a special source (reports, photos etc.) concerning to the alberich coating? Your knowledge about that matter seemed to be unlimited.

Thanks again, can't wait for the next schematic-drawing-update.

I was able to workout three more deck hatches around the front of the bridge this morning :)

Maciek, do you know if on the late war Type VII/41 if the stern reserve torpedo container was remover?
