@Pisces thank you for the info. I played with it in Tutorial mode last night and my results are mixed. I'm taking optical observations with the periscope for the bearings to make sure my bearing errors are minimal, yet out of 4 scenarios I got one perfect target course and speed, and three for which the course was way off. I need to figure out where the problem is (me being most likely, but taking those bearings is drop dead easy and I triple check them).

I saved the numbers and will plot them on the board today. I'll also look at your tools. I really need to be able to plot the convoy course and speed while under way. I hate the thought of guessing the AOB "by eye" and having the target course solves that problem the right way (I know they can zig so maybe I'm dreaming). It (under-way plotting) can be done on the plot table, but it's work-intensive and error prone, especially while playing solo. I'm not even ready to join a crew and get us sunk or cause misses ha ha.
