Yeah imwas on subguru.com and i found one short clip but coulndt understand it fully...but now i am not at home so i cant rwally what it was and i cant look for other tutorial about TMA. So till i get home i was wondering can some captains share some tips about using TMA mainly my problem with TMA is that i cant put all bearing linea on marks on ruller....especially if i have more bearing lines...also i dont know how but hapens to me the first bearig line gets in midle and other bearing lines conected with same contact are around some are left of it some right of the first line so it is imposible to conect them all with ruller properly

You talking about ruler .. you mean frigate TMA ? That is pretty messed up. Luckily you don't need do TMA on frigate most of the time, as you have active sonar and helo.
Sure, even on subs you rarely have chance to stack all the dots perfectly. Usually you only need last dots to stack, as the target may change speed and direction, in which case it is impossible to stack all the dots. Also you have to make change in direction or speed during collection of target bearing, otherwise the solution will not be possible.
You can also use some estimates to help you .. for example you will usually detect targets at some distance. You don't have to know speed and course of the target very well, as it will most probably change in the moment he detect the torpedo. Sonar can provide you with classification and speed information. You can use spherical and towed array to triangulate. Or use UUV to triangulate (interesting method for Kilo, which does not have towed array). Sometimes you can upload probable position of target into link, and let other friendly platforms investigate.

Molonlabe made a tma tutorial mission and a walkthrough document to go with it. It explains the basics of how TMA should be done. I'm sure it is also on Subguru.com

TMA in the OH Perry is close to impossible due to the bearing lines being drawn too short. Try to do TMA with a sub first. And against civilian vessels first also. They (usually) do not have the ability to detect you, so they happily proceed on their plotted course ignorant of your intentions.
