Also, Hector, here's a different one that is a bit more basic on how to plot an intercept course for a convoy in a few easy steps (it's from SH3, but it works just as well in SH5).

Another note: The "shadowy outline" of the convoys predicted position that appears when you plot a course is based on the convoy still being where it was initially spotted, so be sure to check it first to see when it was actually spotted (click on the convoy marker on the map). If it was spotted an hour ago, it will actually be an hour further along on the map than the "shadow" indicates.

Welcome aboard!
