Hitman,

Well, I'm glad that your mod is working and that your in-game repeatability testing is better than mine. I'll have to revisit my course repeatability the next time I take my boat out.

It would seem that a constant -0,5 degree offset (-0.5 in the USA) could be done with a manual anti-clockwise rotation (CCW) of the vernier graphic in photoshop and a re-save it to a .tga file. Quick and dirty but it should work.

I can tell you from personal experience that keeping my 717 ft inboard within a couple of degrees of intended course took a monumental effort (both mental & physical ) when I was at the helm and any sea was running at all. Of course the bubble-heads would have it easier down below without the effects of wind and wave but still, ships were never meant to be driven to within a degree of true course. :D

Had already thought about it, but it would not work because of two problems:

1.- The error is not constant, it moves between 0.3 and 0.5

2.- The error appears only in the last degree of the ordered course, i.e. when the vernier moves you don't notice it but just when it gets to the final degree you see that it fails to move that last 0.3 to 0.5 of degree.

Yeah, I have only steered much smaller vessels (90 ft max) but keeping an accurate course to the degree is far from easy as soon as the sea moves a bit. Hence I think that the curremnt accurancy is good enough -or even too good!- for what a WW2 U-Boat helmsman would have been able to do.

Thanks again :up:
