In SH3 it works well, but in DW I rarely use it, cause my estimate of range is seldom accurate. Its off by 2000-4000 yards sometimes, and I _really_ wonder what Im doing wrong (my nose is nearly hitting the screen when I align the mast and waterline, so no error here).
Anyhow, the 1.03 patch is really good, so if you find bugs with 1.03 you can always post them here and we can adress them or put them on the list for Jamie (so they know about it, doesnt mean it gets fixed).
I share your view when comparing SC and DW 1.00 but I am quite satisfied with DW 1.03.
