Something that might help:
At the end of my last patrol I tested how much my boat gets off course in bad weather. I hadn't really much time so I did some rudimentary test only.
Wind was coming from 312° by a speed of 15km/h. Excluding visibility it was the worst weather SH3 can produce. Here are my course settings, and how far I travelled and how much my final position differed from the estimated one.
Course 90°
after 10km: ~500m difference to North (so to the left)
Course 0°
after 10km: ~275m diff. to East
Course 180°
after 20km: ~75m diff to East (but more due to a slight error in the initial course setting because it was the same after the 20km's)
Course 270°
after 10km: ~600m diff. to North
Doesn't look quite like I would have expected it, I will redo it more precisely when I have more time for it. This should help set the right course in bad weather conditions so it should reduce the error when "real navigating" :hmm:
