I found those values in the ship's .cfg files.
For example:
\SilentHunter 4\Data\Sea\NKLSS_Hakusika\NKLSS_Hakusika.cfg

[Unit]
ClassName=KLSSHakusika
3DModelFileName=data/Sea/NKLSS_Hakusika/NKLSS_Hakusika
UnitType=102
MaxSpeed=12
Length=135.6
Width=17.7
Mast=29.5
Draft=8.7
Displacement=8150
DisplacementVariation=700
RenownAwarded=250
CrewComplement=40
SurvivalRate=80
SurvivalPercentage=45


But I don't know if these values are used for the Rec-manual.
