How do i determine the AOB if playing 100% . I just dont get it and its ruining my SH3 experience .

Study this:

A pretty good tutorial.

I've just been reading through that link and its a good tutorial indeed. I was allready playing on 88% for the last couple of days but I think I might actually go try to play without the map updates, something tells me that its gonna change the whole experience..:rock:

Installed NYGM tonnage mod (playing at 100%) and left Willhelmshaven in 1939 . About a week out the weather turned crap . Medium fog , 15m/s winds . I decided to stay in the AN grids and what do you know . CONVOY . How i ever found it i dont know . Out of the fog appears a dido light cruiser and some other ships .My AOB was about 90deg to port . I headed for the dido and when i got the nose of my sub just pointing ahead of the dido and close enough range (it looked about 3 to4 hundred meters , i never calculated anything,not enough time.) i fired a fan shot of 4 torps (fast,magnetic) the first one detonated prematualy and 2 hit and sunk the dido . I dived to 60 mts and heard that i also got a large cargo . And i thought i couldnt hit the broadside of a barn . LOL

Yes study the Wazoo:s manual charting & targeting tutorial.

Begin the principles of determining target course then "Fast-90" method for attack. There are many tricks you can choose from. Took me some time just to understand the symbols in the notepad placed at scope/uzo stations. Using the "Wheel" (in Wazoo:s manual) helps alot. you can print it out and glue it to a piece of cardboard, make a hole in the middle and stick one of these little brass "two legged" things (don´t know the english word for it) in the middle. well well.. und so weiter. One recommendation is also to begin with Weapon officer helping out with the firing solution. Yor job the as CO is to provide him with proper data. More or less like the real thing i think.

Remember AOB is Your Targets bearing to You. Have fun! :up:

P.S I keep my "Wheel" in my laptop case when travelling just to practice when having nothing else to do! :|\ (weird huh!)

Perhaps you could help me out with an explanation of how to use the wheel? I read the description that came with it but I am still confused as to which of the inner/middle/outer dials to use for what, i.e. which is AOB? which is the sub's bearing to the target, and which is the heading of the target?

Many thanks!

Well well well...

Let's see what US Navy Submarine Torpedo Fire Control Manual 1950 has to say: "Estimation of angle on the bow by observation through a periscope is one of the arts peculiar to submarining. An officer's ability to accurately estimate angles on the bow increases directly with his experience in submarines."

So... plotting is one thing and to estimate AOB is another. If you are looking for realism, you just raise the scope and start practising. I learned a lot with SHI and you can do it now with the SHIII.

Good luck, Commander! :up:

Thanks,

However am thinking more in terms of how you match the outer, middle and inner dials with 1. AOB as indicated when you "lock" a target, 2. Bearing to the target, and 3. (Finding the) target's actual bearing.

The explanation on the AOB finder wheel cutout was just a bit ambiguous, that's all. My eyeballing it and figuring it out in my head can work well in good conditions, but having had to track a target recently in heavy seas with heavy rain and heavy fog at night, I sure would have appreciated the wheel had I known how to use it. Its all ready for me though.

I dont play at 100% realism so maybe this will not work. Once you determine the target's course by plotting its position on the map based on multiple sightings, decide which side of the target you will be attacking from. If the target will be moving left to right set the angle on the bow to 90 deg right. Then manuver into position to approach the target on a course as close as possible to 90 deg to the target's course. A few degrees of error will not be critical, especially if you fire from withing 1,200 meters.

If you want to practice angle on the bow, go to the museum and take screen shots of a ship at various angles and learn to remember how much of the front of the superstructure you can see from various angles. Most attacks take place between 45 and 125 degrees, so concentrate on the angles withing that range. . I hope you find these suggestions usefull.Joe S

Hello Inajira,

I agree with JoeS & Rosencrantz.

As you probably know, the only AOB worth talking about is the 90° (port or starboard perpendicular attack).

Here are some situations to consider:

If you're dead in the water and perpendicular to the target's track (course) the AOB is constantly increasing each moment the target gets closer to your bows.

During a Collision Course (when the target appears to remain at a constant AOB as both vessels proceed toward a collision as their speeds and courses satisfy the conditions for the Law of Sines: a/sin A = b/sin B = c/sin C)

To shoot at a target with an AOB of angles < 60° or > 120° is a waste of time and a valuable torpedo in my estimation, due to the increased chance of a Dud (glancing blow) or Miss (narrower target angle).

The matador doesn't thrust the sword into the bull unless it's for a clean kill. However, I know we all salivate for the chance of many success pennants hung from the ASR as we return to port.

My suggestion is to learn to do it by "sailor's eye" rather than "whiz-wheel".

Cpt Dick "Killer" O'Kane, when the XO aboard the Wahoo, practiced constantly in the Wardroom with a model ship on a "lazy susan" made by the COB. O'Kane would look at the model through a reversed pair of binoculars and call off the AOB, as a shipmate would turn the "susan". He was never off more than 5°.

Where did you get your Aob wheel from? All links seems to end blind.
