Hi y'all
I made some good headway on my U-505 build over the weekend, and updated the
BUILD SITE.
Here are some pictures that should (hopefully) make things clearer about the internal structure of the Type IXC.

INNER PRESSURE HULL:The INNER PRESSURE HULL is the round section in the middle of the bulkhead.
The diameter of the pressure hull changes throughout the boat.
In the kit, the diameters of the pressure hull are the following (at the indicated bulkheads):
- Bulkhead A: ø50mm (2")
- Bulkhead B: ø57mm (2-1/4")
- Bulkhead C: ø57mm (2-1/4")
In the kit, the top (curve) of the pressure hull is ~12mm from the top of each bulkhead.
SADDLETANKS (internal):The SADDLETANKS are the shaded sections on either side of the inner pressure hull; contained within the hull.
Right above the saddletank is the main flooding channel; the TOP of the saddletank forms the BOTTOM of the main flooding channel.
