More Conning Tower photos of U564 a Type V11C
Shows a seat with support, mentions feeding ammo down the shoot etc

PS I dont know what the guy is doing in his

The German U-Boat Base at Lorient France: August 1942-August 1943: Volume Three by Luc Braeuer ?Or any of his books in this series? Looking to find more pics of the U-505 as it comes back to Lorient after it was bombed on Nov 11t, 1942.
I digged out the book and had a look. Although U-505 is mentioned several times throughout the book, I can't find any photos of it.
Fantastic Don.
I hope this all goes well.
Look forward to getting it in some way soon.

Ps I hope Casement don't put it out with a massive premium. As a unique specialist tech doco I'm assuming in hard book form it would be quite expensive. I wonder if the PDF from them will be the same.?
Hello Fillippo,

As far as I'm concerned, "Skizzenbuch: U-Boat Type VII C Project" is complete. I do not plan on adding anything to the 516 page document. Possibly some grammar corrections and having the two (2) pages allocated as a foreword done by a friend.

A book publisher Casemate Publishers UK is looking at Skizzenbuch as a possible e-book in a PDF Format. They have downloaded my full PDF file "Skizzenbuch 11 x 17 - M + I.pdf and will let me know their decision in about 2 - 3 weeks. 

However, if they decide not to publish the PDF, then I will absorb the expense by getting a US copyright ($55.00 for multiple authors) and create a US State of Georgia Publishing Company LLC ($150.00) sometime in November or December of this year. Then in January, I will purchase CopySafe Software ($295.00) to protect the distributed free PDF file.

Free distribution may be done through several websites to be determined...

Hi Don and Tore,
I was wondering when you expect to finish the work on Skizzenbuch.
You know that there are several U-Boat enthusiast waiting for the availabilty of your work, obviously paying for it...
The problem has already been addressed, and one possible solution is to make a file available and printable on demand, upon payment.
What do you think about ?
An answer would be welcome.
Fillippo from Padova
Don, very good. As to the very complex picture of fuel economy and the many way of operating dieselengines-generator/E-motor I guess it would have been an interesting thing for an IT man to make an optimal programme for the various running modes with the numerous variables.
Hello Mr. Tore,

I took your advise and changed the thrust pads to ahead and astern...  I was not going to add the info discussed about fuel economy running. I was just curious...

Also, I updated Skizzenbuch to reflect the changes in Dropbox...

Don Skizzenbuch page 426, 427, 428.

Checked OK. May be you should use ahead pads and astern pads for the Michelle thrustbearing instead of forward pads and aft pads.
Don fuelconserving.

You are entering into a very complex area in the operation of the submarine diesels, introducing many  unknown elements as the submarines variation in water resistance related to the speed, propeller efficency in relation to revs., dieselengine variation of specific fuelconsumption related to the bmep ( brake mean effective pressures) etc. We did not have access to all these figures so we did not have any instructions as to the variation in the operation modes.
The specific fuelconsumption is usually measured at the testbed using a waterbrake, following the theoretical propellerlaw, the result is not always matching the real thing onboard, certainly not on a submarine having so many variables. In your proposal you introduce a load which increases the BMEP outside the propellerlaw graph (waterbrake).  I have no figures, but should imagine your theoretical suggestion could be viable, but you have to watch your engine (exhaust temperatures) carefully not to overload the engine (excessive BMEP). I don`t think you should include this topics in the Skizzenbuch, its a topic for the real theoretical experts.
Hello Mr. Tore,

I updated pages 426, 427, 428, and added the index back to Skizzenbuch. The latest version of Skizzenbuch is in the Dropbox folder...
