I'm in the training wheels phase of manual targeting myself. For a quick AoB since I've already figured out the course and range of the ship I go to the map and use the protractor tool to get my AoB.

I start from the Uboat along the bearing line I intend to fire from (hopefully my bow is pointed in that direction as well). When I intersect the course of the target ship I then move along it's expected path. The angle created is the AoB.

If the right side of the target ship is facing me it's AoB to starboard. If it's left side faces me it's to Port.

A quick recalc of range and if you have time recalc speed, fire and cross fingers.

I believe this is called AoB for dummies. (a.k.a. for me).
