Silent Hunter 3 community manual

[Weasel]

Determining target speed in SH4 is done the same as it was in real life. A track is taken to the target including distance and angle on bow. You can then lower your scope if you wish, and wait a certain amount of time. I normally wait about 2-3 minutes. You then raise the scope and once again conduct a distance and AOB to determine speed. This is a per real life and basically what they do in SH3 but manually.
