most often the unused attachment points for the net cutter

Gotta agree on this, You can see that further front is 2 smaller ones. Seems the holes in the biggest aft have been welded shut at some point.

Thanks guys for the information. This would explain why I was not seeing them in the late-war boats. Thanks again!!

I have located the deck vent for the Bow Driving Tank and the Stern main buoyancy tank but I can't found the deck vent for Stern Driving Tank. Do it have a deck vent? I don't have any picture of the stern to check this and I can

Thanks Siara. I have this already. This is what makes me believe that there is a missing vent on all the plans I have. If you look closely that all three valves, they all go to the deck. Both the Bow Driving and Stern main buoyancy tanks have deck vents, but where is the Stern Driving Tank deck vent? Surely not all the plans could be wrong ???

Hi Siara, thanks for the help but no, the vent in the picture is for the Stern main buoyancy tanks between frame numbers -1 and -2, the Stern Driving Tank is between frame numbers -10 and -11. This missing vent should be approximately 2.5 m from the end of the stern.

After looking at all my plans again I am starting to think that the Stern Driving Tank was only found on the early U-boats like U-570. By about mid war they have removed the Stern Driving Tank and just made the Stern main buoyancy tanks larger.

In the plans I have for the original form of the Type VII, VIIB and the very early VIIC, the Stern main buoyancy tanks are smaller than the later VIIC. I also see that some of the plans for the late war VIIC/41 have

TBC...

Hi Siara. I was just wondering how many cleat did you found on the deck? I have only located the same three cleats (marked in red below) that you show in your pictures. Did you found any more? Thanks Simon.

Some boats had extra set of cleats as seen on the first picture on the side of the conning tower. between front, and back sets of railings.

I dont know what these things were there for, but i do know- these are not simetrical. If you look closely at the shots, you can see that the one on the port side is slightly protruding forward. Since i have corrected the placing of these parts on my model.

Thanks again ;D I think I have seen them also on the late-war u-boat like the VIIC/41's. They look to small to be diesel inlets and I believe the water tanks were all in the bow section of the boat, so unlike they would put an inlet here on the stern section. I wonder that they are for ??? Hate the idea of not know :(

Antislip strips.



TBC...

Hi Siara.
During your research on the anti-slip strips, did you found that the anti-slip strips were a narrow plate with a double row of bolts? Thanks, Simon

PS. Siara, that is plate below and right of the capstan, with the funny outline? I seen them on the early Type VII's but not on the late-war VII

Yes- double row studed strips screwed to the deck.
You can just make it out from that shot of U-405:
