The arrival of the ship at it's base, but I am not certain from the movie that it is the right ship...

Hello Siara,

You are correct, right now you can only see the movie with my link, the DVD is not yet available.  I think the video should be out in a few weeks as they sell them from almost all their programs. The video has already reached over 1000 views so far, with such a popular subject, they will need to make a DVD I am quite sure.

Hi Trierarch. I have only got back from the city (I live about 1

I have always wondered that were the total lengths of the Type VIIC are. So while reading The U-boat The evolution and technical history of German submarines I found the numbers. Just thought some of you would be keen to know them.

Version   Total length (mm)

VIIC      67,100

VIIC/41   67,230

VIIC/42A   68,730 (Final VIIC/42 version)         
VIIC/42B   73,400
VIIC/42C   Either 68,730 or 73,400

VIIC/43   68,730 (Total length was not decided)

Hello Simon,

Administrative problems seems to bug us all over the world, I have been restauring and reselling a few flats, and one of the biggest constraint was often the French administration.

Concerning the movie the main diver is Innes McCartney.

I copied a few facts about him, but I am certain that the people that live in England can somehow contact him.

Innes McCartney is an historian and nautical archaeologist, specialising in 20th century naval vessels. He lectures widely on a number of associated subjects. A passion for shipwrecks has led to some famous discoveries, including the submarine M1 and the battlecruiser HMS Indefatigable. His previous book, Lost Patrols detailed his uncovering the 121 submarines sunk in the English Channel. He lives and works in Penzance, Cornwall.

Sorry you can't watch it, but apparently they have displayed it over 800 times in less than an hour... I tried the link and it work on my computer, may be try again later.

In the mean time here are a few pictures:

Tiles details





On this one the finger at the bottom left corner gives you an idea of the scale


 

Hi Trierarch

Could you see the seam between tiles?

Thanks, Simon.

[Trierarch]

Hello NZsnowman,

Yes you could see the seams between the tiles. The tiles seams not very large, and apparently they are not all the same size either.

On this picture you can see a seam at the bottom left:



Here is a view of the pierced plate being glued onto the basic coat of plain rubber. The basic coat is glued directly on the hull. They say rhat all flat surfaces were covered, including the guns shields. Two exceptions are the CT floor and all the hatches.



On this photo you can see a plate separating from the boat surface. This gives you an idea of the thickness of the rubber.

Here are some shots of the 3D modelisation they used for some movie sequences





 

[Trierarch]

As you are drawing plans maybe this shot will interest you too. It is one of the propeller that has lost its cover. This way you can see the screw that maintain it in place.


 

[NZSnowman]

Thanks Trierarch for the pictures

[NZSnowman]

Does anyone know if the height between the top of the pressure hull and the deck was greater for the VIIC/41 compare to the VIIC? I measurement the distance and I find that the VIIC/41 is approximately 200 mm higher. Is this correct?

Was it higher to make more room for piping etc...?

Just an update on this question, if a few people are wondering

After looking at the u-boat plans a little bit more, I believe that the deck height was the same for both the VIIC and the VIIC/41, in fact all the Type VII

[NZSnowman]

Does anyone have any pictures of the inside of the keel for the Type VII's? I am after any pictures of the frames within the keel.

Thanks, Simon
