This is not the first case... few times before I used hydrophone and stationary three bearing method to determine target's course... but when I surface to sprint to more favorable position for attack I almost always run into target... I'm not talking about some small error of 5 maybe 10 degrees but 50 or more... totally different course...and I became very good with hydrophone (thanks to months of bad weather)... so my error is out of the question.

Hello..

Don't know if it's relevant... but in what year are you now?
