Pappenburg gauge and cryptic markings

I've got it:

The left gauge is for precise depth when shallow. It shows the depth to keel under the command room, and the hull outline gives a reference to determine which parts of the superstructure are submerged. This should be familiar from SH3. The nonlinear scale is due to water pressure acting against a reference air mass; as the volume of air is reduced by pressure, additional pressure has less effect.

The right gauge is for *angle* of the boat, with the middle scale probably showing degrees. The vertical orientation is confusing for people used to spirit-levels and other types of horizontal "bubble" gauge. The extra scales to left and right are correction factors to determine the depth of the foredeck and aft keel (when angled up), and the afterdeck and fore keel (when angled down), relative to the keel depth shown on the left gauge.
