yep no worries, i get it now, my rule cant apply as the direction of the point changes with the way the enemy boat is facing.

so essentially 0 deg of the target vessel isnt constant it is always moving.

PEOPLE FORGET WHAT I SAID.

AOB is for the enemy's ship...not yours. His relative bearing to you is what you need to think of.

He sees you at a relative bearing of 330.... his angle on bow to is 30 degrees left (360-330=30). He see's you at a relative bearing of 70 degrees....his AOB is 70 degrees right.

It DOES NOT MATTER WHAT angle (relative or true bearing) you have to him. Only his angle to you. It's confusing because it is constantly changing in most situations.... The ONLY time you can use your Relative bearing to get exact AOB of the enemy is if you know his True Course. Then you can know that at certain relative bearings what his AOB would be to you based off of that true course you calculated.

using Gaps example.......... Enemy ship on true course 090.... you are true course 360T. Your relative bearing TO the enemy is 330. Because you know that you are on a perpendicular true course to the enemy ship... you know that if he passes your bow (relative bearing 000, true bearing 360 (you are headed 360T) his AOB will be 90 degrees right..... you can then subtract 360 from 330 to get 30 degrees...subtract 30 from 90... and you get an AOB of 60 degrees Right on the current relative bearing of 330........340 would be 70R, 350 80R, 000 90R. Confused yet?

this is confusing haha. so what is the AOB used for then? what would a u boat commander back in the day have used it for and why?

It is used so you can work out where a ship will be in the future (time+speed from the direction of travel of the target).
When you know this you can make sure that a torp is also going to be there
