Hi Hanns, If anyone could complete a project of this scale - I belive that person to be you mate
.
If you do start, if there's anyway I could help my services are yours
.
Not sure what I could do for you, maybe some Interface design or something.
As for what is needed in a uboat and so far has not been touched by the Silent Hunter franchise is a proper working Stadimeter.
Current Sh3/4 type use's a vertical stadimeter, where as Uboats had a one that switched between vertical and horizontal. Great when mast height and ship length are known - using stadimeter with these dialed in obtained the AoB.
Best of luck with the project mate
