U-Boot secret navigation book

[kartengruppe]

Hi,
sometime I post some kriegsmarine maps used on the "Project: Printable navigation charts of the SH3 worldby" (Karl Heinrich)
post: http://www.subsim.com/radioroom/showthread.php?t=213987&page=2

Now, I would upload the D. 2230 V-Tafel edit by Oberkommando der Kriegsmarine

This is the Secret manual used by German UBoote during ww2 to compute the optimal route in approaching vessels to be attacked.

It was composed by text instructions (attached) and tables (only few pics here)

My book was fot the Gothenhafen Uboot base use

I know you, commanders, will like it (I need feeds).

& pls visit my collection on www.kartengruppe.it

Fascinating!...even if it sorta triggers my 'post traumatic trigonometry syndrome' I barely passed with a c-...math ain't my strong suit! I'm gazing up on the mancave shelf at my old 1933 leather-bound copy of Burington mathematical tables and formulas my engineer dad loaned me in in 1967!!! It didn't help much "Natural ?? Trigonometric Functions"??!!:nope: http://d.gr-assets.com/books/1266642349l/780250.jpg unnatural maybe !:shucks:

For anyone interested, for purposes of the Wolfpack simulation I re-created this in Google sheets using scripts with push buttons. If anyone is interested please check it out. It is only valid for own speed of 18 kts, and all targets speeds down to 4 kts and a minimum distance of 9000 m.

The purpose of the original document was to tell commanders when to turn and by how many degrees to ensure a minimum distance to the target is maintained while overtaking.
