Don.
A German; I presume naval architect Køhl, has made a longitudenal drawing of a VIIC/41 based on, I again presume, a Norwegian drawing (reference Plan 314) unknown to me, where a lot of infos are noted including the plate thickness. I have put up the figures in a table starting from the aft pressurehull frame 0.
Frame no. Plate thickness mm Distance in mm Schuss Remarks
0 35 0 0 Curved endplate
0-12 16 6000 I
12- 18 appr. 17 3500 II
18 app.-27,5 17,5 5500 III
27,5- 36 appr. 18 7100 IV
36 appr.-50,5 18,5 9100 V Turmplatte mm 22- pressurehull top plate in the tower joint area ( not the towerplating)
50,5-62,5 18 7200 VI
62,5-75,5 17,5 7900 VII
75,5-81 16 3100 VIII assuming bow curved endplate is 35 mm
The 22mm topplate in the tower area is due to the relative large openings in the pressurehull.
