i guess he is speaking about the RPM charts that allow you to determinate the speed of the target just by listening and counting the revolutions of the propeler per minute. you can download it with the sound trainer by greyrider, here: http://www.subsim.com/subsim_files/patches2005.html

when they cross the 0.. watch the fireworks :P.

I don't get it. I tried it yesterday on a large convoy. I was 90degrees to the ships. and manually adjusted the firing solution as in the quote above. When the ships came, the one in the front shadowed for all the other ones in the back, so the torpedoes only hit the one in front. I understand that I have to fire early. but how much early to hit all at the same time?

Even though the explanation were simple. I believe I need a simpler one

cool post! although i haven't tried it yet, the idea looks amazing!! imagine being aboard a destroyer and trying to figure out where the sub is from the explosions!!

that is very interesting but this will only work if you use electric torpedos ...
if you use regular ones as soon as the first ship of the column sees it
they will change course and you might hit the first but the rest of them will have more time

How do you that ?

[Cpt. Stewker]

By listening to the propeller sounds.
Depending on the ship, you can find out the speed by how many revolutions the propeller(s) make per minute.

CHUG-chug-chug-chug CHUG-chug-chug-chug CHUG-chug-chug-chug...

his four bladed propelar turns 28 times per minute. For a C2 that kind of engine effort translates into 7 knots. Speed confirmed (if this was way over your head don't worry, there's an excellent academy mission download for training yourself in the use of the sonar, done by Grayrider and Captain Nautilus I beleive).

It is called "sound training" and iirc downloadable either by subsim or ubrs..
