Hello Alex,
The U-Boat manual.....
M.Dv. #381 U-Bootskunde f. U-Boot Bauart VII C-1940 Geheim
c) turning circles.
Turning circle diameter
as a function of rudder angle and RPM rate
About water:
Type------Rudderangle--------Surface turning circle 0 in Meters
---------------------------A.K-------G.F.-------H.F.------L.F.--------K.F
--------------------------n=471----n=435----n=340----n=275----n=180--Turns of prop
----------------------------------------------------------------------------------
A---------32-Deg----------270-------265------253-------245-------230
----------30--------------295-----------------260-------250
----------25--------------350-----------------310-------290
----------20--------------418-----------------370-------345
----------15--------------530-----------------475-------440
----------------------------------------------------------------------------------
B---------32-Deg----------286------280--------270-------265-------253
Below water:
Uboat Type VII C in attack circle with 500 meters radius.
I hope this helps,
Kind regards,
