oK I Know this has been asked but..

I dont find Wazoos Plotting Tutorial helpful because of the lack of tools i posses. I only have tools offered in Rub 1.42. So when i read Wazoos tutorial it doesnt help out that much. And when i look at other manuals it never calculates for 100% realism. It uses the hydrophone lines to plot, and there are no hydrophone lines with 100% realism. So what do the other 100% use?

I play 94% (event cam switched on) and use the in-game tools.

- ID vessel with eyeball
- Use mastheight methode to get distance
- Use eyeball to estimate AOB
- Use stopwatch to get speed

I find the "exact plotting on the nav map method"" that many players use very unrealistic. But I did try that as well and it works good.

But using the in-game method just seems much more realistic to me.

my problem comes with the speed calculations.. I always miss, too slow and it passes aft of the ship.. How long do you usually take to plot, intercept, shadow, and kill

[RevRaz]

How are you doing your speed calc?

[Salvadoreno]

i guess.. lol

As long as you can stay on the surface, but out of the detection range of the ship you are tracking, you can get range and bearing from your Weapons Officer, and use that info to calculate speed.

1) Put the WO up on the bridge, stop sub.
2) Click on WO's binocular icon, and he will give you range and bearing.
3) Use the ruler tool to plot the mark on your nav map.
4) Wait 3 minutes 15 seconds of in-game time (use TC if you like).
5) Repeat steps 1-3.
6) Use the ruler to make a line that connects your two plots. The length of that line in meters divided by 100 is your target's speed in knots, so that if the distance were 300m, the target is moving 3 kts/hr.

More advanced technique: Use Wazoo's nomograph:

a) If you know how far the target has travelled and you know how much time it took, then you can calculate speed.
b) Decide on a time interval of at least 1 minute.
c) At the beginning of that time, stop sub, plot range and distance of target.
d) Repeat step c at the end of the interval.
e) The nomograph has 3 lines: time, distance, speed. Use the marker to put X's on the time and distance used by the target.
f) Use the ruler to draw a line through the two X's that extends thru the speed line. Where the ruler line meets the speed line is the target's speed.

Both techniques assume you are surfaced. A yet more advanced technique involves being submerged. Again, you can use your WO to calculate range, and the bearing will be on your scope. Or, if you can use the stadimeter in the scope, you can bypass the WO, and get your own range. This gets really tricky if the weather is worsening. Be sure not to leave your scope above the water for any time more than absolutely neccesary to get your measurement. (One guide reccommends 5 seconds only!)

Lastly, another method you can try if all else fails is to run a course parallel to your target, and then match speeds that way. You can use your hydrophones to keep track of your target, which should be at around 90 or 270 degrees to you, and fiddle with the throttle until you match speeds. A few periscope checks during the process will help.

I plot on a REAL paper map, taking my subs movement into account... if I can do this on my table at home, why should this not be possible in reality ? I don´t get it... :huh:

Because this plotting needs numerous very excact estimates of distance amd heading. I have never read detailed German attack account, but I did read many Dutch attack accounts, and that is not the way they did it. They plotted to get a general idea. They did not plot exact to the meter or degree and use that plot to launch their torpedo.

I find using the range/bearing provided by the WO also very unrealistic. He is too exact and can even estimate range when the ship is almost invisible. I feel like cheating when using his info.


:D

So how exactly did they do it? I'm always interested to find out how they actually did these kind of things during the war.
