Hey All,

Solution for Angle on Bow

If it's on the port side and I have a bearing of
150, and it's course is 180 then

Angle on bow = Course - Bearing = 030 deg

If on Startboard side and I have a bearing of
250 and target course of 180

Angle on bow = Bearing - Course = 070 deg

Is this correct?

Just need u guys to check it, makes sense to me,
angle on bow is angle from their bridge to my U-boat.

Thanks

Angle On The Bow is a simple question of what HE can see. It is the angle he would see you at if he was looking at you. All you have to do is imagine you're him. Your heading and the bearing you see him at have nothing to do with it.

Here's a set of pictures that will help you get it right every time:

Imagine you're standing on the bridge of the target ship, and you're holding a flashlight straight ahead. Then you take another flashlight and aim it at your submarine. What's the angle between the two beams?

That's your AOB.

ok seeing as though i have only just found out what AOB means, i think i may be able to help with the most useful trick you will probably learn about the subject, as i haven't seen it in the forums yet.

Ok so if AOB is the enemy captin's bearing of you all you have to do is simply take a back bearing.
Now i havent done this in a long time and being in the british army, instead of DEG we use MILS. but the math is the same. so stick with me here.

If the bearing of the enemy ship is from 0-180 DEGS (starboard) then take the bearing your watch officer gives you or the bearing you take manually on the map and ADD 180 deg to the bearing.... this will give you your back bearing.

If the bearing of the enemy ship is 180-360 DEG (Port) then the opposite is applied and 180 deg is subtracted from the bearing of the enemy ship from you.

Now like i said i havnt used this for months, and it was in mils not deg. but hey the maths is all the same

Good hunting folks and i hope this helps

That's not right. If he is bearing 30 degrees from your bow then the opposite bearing would be 210. If he's heading directly toward you it would be 210. If his course is parallel it would still be 210. If he's heading directly away it would still be 210 by your example.

AOB has nothing to do with that at all. No matter what bearing you see him at, if he's heading straight toward you the AOB is 0. If he's 90 to your port then the AOB is 90 degrees to starboard, because that's where he sees you. If he's heading directly away from you then the AOB is 180.

AOB is the angle HE sees YOU at, nothing else matters.
