d) three sections? Which structure are you talking about ? The stern torpedosuppor arm is very far from pressre hull...

The torpedo tude has three sections. It were no torpedo suppor arm, there a large size pipe that ran above and to one side that is the control arm to the torpedos door.

PAG. 1:
a) the top of the keel is only a sign that shows the border of the keel, or it was a structure, like a plate; in this case, in consideration that the Ballast Tank. 1 was open to sea in its lower surface, was this plate perforated? And finally, the keel was part of MB Tank 1 ?

Its the top of the aft keel casting, which is just below Stringer 1

You can see the lines of rivets on the casting

Thanks Snowman,
I hope in other answers ( pag. 4 and 5 ) and other ideas, if available...
About your first replies:


PAG. 1:
a) the top of the keel is only a sign that shows the border of the keel, or it was a structure, like a plate; in this case, in consideration that the Ballast Tank. 1 was open to sea in its lower surface, was this plate perforated? And finally, the keel was part of MB Tank 1 ?
d) three sections? Which structure are you talking about ? The stern torpedosuppor arm is very far from pressre hull...
e) Were those two beams symmetrical ? Is there a drawing ( plan ) that indicates their position ?


PAG. 2:
b) ok, they are not what I tough, but were what ?


PAG. 3:
e) finally a good idea that I never though about: see the stringers from outside...I have many photo of Laboe U-995: I'll try to identify the stringers from hull plates deformations....

Hi everybody,
this is the last time I ask help to the forum's members about this question; if I'll obtain some new informartions, I'll try to do by myself.
For convenience, I post some drawings, extracted from David Westwood book, on which I indicated a part of my questions...
Any help is welcome.
Thanks in advance.
Filippo
