Authentic method of getting firing solution?

How do you do this with the wheel (which, if I understand it correctly, gives the solution based on two observations only)?

I was thinking about building the wheel but gave it up for now. I was doing some serious plotting but now nearly I don't draw more than a single line - a general course if I need to follow. It all started when I removed my position from the map (as to use celestial navigation). Suddenly I have found myself calculating in my head bearing, speed, course etc. I started to see things differently, started to fell relative courses etc. Another thing is that to be realistic you need to make some observations like timed hydro readings, manual range through your scope etc. The more you spend on the see the more it's obvious and very quickly you just know what to do, how to react. This gives a very nice feeling of being a true, trained and experienced captain who has everything in his head!!

My problem is finding enjoyable balance in the game. First I used map contact updates and weapon officer assistance. Soon practically every torpedo I fired hit. Then I turned off weapon officer assistance and used the updating map contacts to plot tracks and generate solutions. Nothing changed, practically every torpedo hit. Recently I turned off map contacts and started plotting manually based on observations. Now I miss about 10% of the time, with something like 50% of my torpedoes hitting within 5-10 meters of point of aim.

The only thing that has changed as I've turned on more realism, is that I now only fire from good positions. No more instant weapon officer solutions against zigzagging targets in poor positions. Also, gameplay has become a lot slower - plotting takes time.

I'm not ready to go through the trouble of navigating myself. That would slow gameplay even more. With my current settings I already find the game a bit too tedious to my liking. A real captain would have had crew to do some of these tasks. Unfortunately the game crew is too good at its jobs, making hitting targets too easy for the game to be enjoyable.

So I'm looking for a method of playing the game without making tedious observations and plotting, being able to hit about realistically, and not using the way too accurate crew observations, if at all possible. Good suggestions are welcome.

One solution I'm currently considering, and will test out next, is this:
- Overhauling the target on surface, keeping a long range and a general bearing of 90 or 270 to target. This should give me an idea of target heading as I visually observe aob changing during the maneuver, as well as some idea of target speed.
- Submerged approach on a (as close as I can visually determine) perpendicular course, setting speed, when possible, so that the bearing to target keeps constant. This gives me a good idea of target speed and puts me in a good firing position. I can also stop and measure target speed quite accurately using the stopwatch and target length, if I am in doubt.
- Visually verifying aob and measuring range through the scope, and adjusting the TDC accordingly, just before firing.

I'll have to see how this works out. I just fear that I'll end up with worse solutions than a real captain would have in a similar situation, and won't be able to hit much anything. Hopefully I'm wrong about this.

The wheels are great! Transforms your game. You never need to waste time on plotting to get course again. Unless visibility is extremely poor, I find I often don't draw anything on the map at all, although this does depend on what it is I'm hunting.

The fact is that in RL neither the GErmans or Americans wasted their time using bearing plots -just too inaccurate. There are far more effetcive ways of doing it (although I still will do the 3 min 15 sec thing occasionally, if the situation calls for it, for example if I'm already sure of course and I'm just lying in wait, it's an easy way to confirm your earlier estimates)

As for finding manual plotting a bit too slow...well, that changes soon. The challenges never really stop too. With plotting etc you can get into position and make an easy kill some of the time. There are lots of contacts you will be unable to catch that way. A big part of the joy of this game is the discovery of new ways to get those targets you used to just give up on.

****breaths deep*****

OK....long story short:

I have been already for some time doing an article exactly about that: How the germans collected data for their firing solutions in real life. The information is far from complete and easy to get in the web, I have been researching the matter for several months and now I start to have a clear picture. I can't sum up what I am putting together in an already 12+ pages long article (with pictures included), but I can tell you that it is 100% sure that germans did NOT make any plot on the map for the target solutions (Though they certainly plotted the contact info from BDU about convoys until they made visual contact for the first time), unlike their american Silent Service counterparts. Aboard a german sub only two persons did the full job of getting data and feeding the TDC: The commander at the scope (submerged) or the IWO at the UZO (Surfaced), while a petty officer auxiliated with some calculations and recognition manuals, and fed the data into the TDC. And they did it "on the fly", without any plotting. That was achieved through the combined use of certain manouvering tactics (Constant helming and bearing) during the approach at long distance, and the use of the specific instruments in the U-Boot optics when already close (submerged of surfacer), like the Rangefinder, Course finder, etc.

And no, they did NOT make always simple estimations of the AOB like the americans, they used instead a device (Mechanical wiz-wheel linked toa split prism optic) in the scope for measuring that.

The article should be available first in spanish and later in english in some time, I have written it already and I'm now busy drawing some schemes and re-organizing and revising the text.

P.S. I'm also working on that real life periscope wiz-wheel for printing and building up your own one. Hopefully also someone who knows how to add moveable dials to the game (Like the 6-dials simfeeling mod) will be able to help me adding it to SH3

Wow very impressive, can't wait to put my hands on it but I don't know a word in spanish... so till now it's good to know that my approach is quite good! With celestial navigation it gives a very nice feel as a commander.

Gut gemacht!

I started to see things differently, started to fell relative courses

Yes Hadrys, that's the key....

The plotting we are used to in SH3/4 asumes the perfect knowledge about our sub's position, but in reallife that was very difficult if not impossible in the middle of a sneaking approach. Thus the methods developed by germans involved heavily relative comparisons between what the target and the own U-Boot were doing, not to were they were located in GPS style coordenates . For example, constant bearing of the enemy plus an AOB estimate gives you speed with simple Law of Sine maths, and constant bearing of the enemy at 90º/270º allows you to easily get a very exact AOB with rather simple maths or even some pre-configured tables. Non constant bearing can also provide rough speed estimates, applying corrections and so on.

All that was done during the long range approach, then the U-Boot submerged for the close approach and did ocasional periscope checks. By the time she was on firing range, most data were well confirmed....

There will be a english version also

Hitman,
I am awaiting your info and work. I am sure it will be a hit.

To be even more specific I try to hit from 90° and really I can't explain right here right now how I do it. Simple relative position which I can draw even on a piece of paper or in my mind. Check how changes contact sound, get visual (now when I play at 1680 resolution this is even better because far targets look great and very precisely getting out of the fog so I can later observe masts, lines, details etc. Just gives a good fell of using great Zeiss optics). The most important part of it is that now when I hear target on bearing 291 I instantly know where it is! Looking through the scope I can tell quite good what's the range, than use "double peri view" to give a more accurate range. This is all very simple, intuitive and fun but hard to explain at first. Just practice! Also when using T1 torps the attacks are very lethal up to 2 km.

Try celestial navigation as we probably finally figured out how to calculate longitudes!
