Default AOB Question

Hi

Quick question. I have always taken AOB to be from the bow of the target ship where Jack and Rose did their little "I'm flying" scene in Titanic.

However when you look at certain diagrams like even the one in the guide here on Subsim or even in the AOB control in Wolfpack, it gives the impression that the reading should be taken from the middle of the target boat.


So it is from the bow and not the middle of the target boat?

Thanks

It doesn't really matter that much from where on the boat the angle is taken, as long as you are consistent. It matters that it is the angle between the target course and the line of sight.

Only if you are extremely close will this angle be any bit different for different places along the longitudinal axis of the target. A target length of 150m at 1km distance is only 8 degrees wide. At longer distances the difference is proportionally smaller. When setting the AOB, as long as you point the scope/UZO to the same spot as where you measured it you should be ok. In the middle of the target is just easier.

The AOB dial on your TDC represents a ship moving 'north' or up. There is a right side and a left side. The dial does not change, so that particular dial is really a diagram of the target ship. Always pointing north or 'up'.
The tip of the needle is your submarine. It isn't any more complicated than that man. Put the needle where you are located in relation to the ship you are targeting and your angle of bow problem is over.
If the targeted ship is coming towards you, you want the tip of the needle to be be in 'front' of the ship.
If targeted ship is moving away, the needle should be 'behind' the ship.
You are the needle. Go stab something now.
