this tutorial is sorely needed

in response to those skippers who have asked to see targets moving away, i have increased the number of ships in this trainer to 17.
now there are targets all over the three sixty, some docked and some moving. take your time with it, and remember that even with targets moving away, the same rules
apply.

aob course trainer ver 1.1:

i will demonstrate two targets moving away from the submarine, and then let you skippers have a go at it.

in the first pic, you see a target going away, it bears on bearing 68°, since the bearing is less than 180°, we add 180°, it has a port aob, so we will add the aob which is
112° port.
68° + 180° = 248° + 112° = 360°
this targets course is 360°, or 0°

in the 2nd pic, targets bears at 11°, less than 180°, add 180°, 11 + 180 = 191
now with this target, it has no port or starboard aob, all you can see is the targets rear end. remember aob is measured by how much the bow of the target
is angled away from the vertical aiming wire of the scope or tbt. looking again at the target, we can see that this ships bow is angled 180 degrees from the
aiming wire, going away. the target has a 180° aob. so you would substract 180° from the sum of 191, 191 - 180 = 11, and the course of this target is 11°.

remember that because the submarine is heading north at zero degrees, the bearings are relative and true at the same time, to get real tricky, you could edit the submarines
heading to different settings, and then measure aob and target course, remember that if you do, your bearings and courses of the target will be just relative to the submarine, and not true bearings.
but when plotting relative bearings and courses on your map, they will be true bearings and courses.

Now this sucker goes straight to the Sub Skippers' Bag of Tricks thread, do not pass Go, do not collect $200! Please copy both tutorial posts, plus the link to the latest version to the end of that thread. This is amazing, crucial and greatly done. Take a bow sir!

Apparently FileAffront has struck again! Anyone got a link for this? Missed it before, and I'd sure like to see it.
