Simon.
I have no means to measure the angles, but am wondering about your blue casingdeck image. I the way of the lower wintergarden I guess the casing deck has a small 2nd. widening between frame 41+ and 47. See picture below. I have some photos showing KNM the decking in the vicinity of the snortmast see below, on the Kaura decking we did away with the wintergarden and the 2nd deckwidening.

Hi Tore

I checked my photo's this morning and many the late war Type VIIC/41 don't have this 2nd widening. I imagine near the end of the war the Germans were keeping the boats very simply.

I guess you are right. The below picture of U 995 with wintergarden from may 1945 shows she didn`t have this widening.

Tore, in almost ever photo of the late war 'planked' deck, including KNM Kaura/U-995.  I can found large darker holes along the outer edge wooden plank, right next to the sidewall casting, You can see them very clearly in the photo of U-249. They are space every 400-500 mm around the edge and are used to fix the outer wooden plank to the deck frame.

You toll me that the Germans used wooden plugs on the deck, so my question is why are these one not plugged like the main deck; why are they bigger (are these fixed with larger bolts than the main deck). Tore can you remember anything about these holes?

Simon.
I cannot recall we ever had so many holes as on U 249, but we had larger holes for the stanchions of the railing which was pretty much used in peacetime. In war times and during exercises they were removed leaving only the holes in the wooden deck along the casing. The reason why they were removed was due to rattling while submerged.
Below a photo of KNM Kaura with the stanchions fitted.

Hi Tore

I was able to workout the locations of the stanchions base on your photo's and a late war Type VIIC plan. The Germans changed the layout of the stanchions between the early war and the late war Type VIIC's.

I recheck my photo

I believe you are right checking all my photos, the wooden planking has a regular row of holes at the casingsides as can be seen on my photo of KNM Kaura U 995 below. The holes are not on the steelpart of the deck so I guess they are a part of the wooden planking construction ( fastening) to the steel support and probably at the point where the transfer girders joins the casing, see photo. I take it they are boltholes and have no other functions.

Simon.
If you mean translation.
Seitenlenzrohre trimmleitungen auf U boote= side drain ( branch) pipes, trim pipes on submarines.
Hilflenzleitungen abfallrohre der hilflenzeinrichtung ( entwasserungsrohre nach dem shiffsinneren) =auxilliary drain pipe.  Slanting branchpipe from the auxilliary drainpipe device ( Drainagepipe towards inside the ship).
Hauptlenzleitungen= main drainage pipe.
To have a correct translation you  need the reference drawing, but may be this will do.

I guess your work on the VIICs makes the type XI research much easier

 :)  Alot of work guy!
The Two types do have some things simular. But they also have alot of differences too! It would be nice to see something done for the Type IX however. The Type VII gets all the press because of the movies! ::)

Dan

Does anyone know if the German change the location of the rear deck casing bollards, as I have two drawings showing two different locations for them :(

The dockworkers are happy today as the deck of U-1308 was finally laid. Where still work to be does like adding the missing hatch covers and the watertight containers. The hardness thing for the dockworkers was to workout the outlay of the bridge casting.

Simon looks very good.
A question on the saddletanks manhole covers. Apparently there are variations, I seems to remember they were oval shape like on the drawing below and the photos of U 995 and your photo of U 249. I assumed your research on U 1308 has resulted in the arrangement, two round and three oval, on your  drawing.
