Realistic torpedo attacks

[Dr_Sir]

Hello to all seasoned sea dogs

I got SH3 a while ago, and never before has a game got me to buy so many books!

I really want to learn how to shoot torps by myself, without the godlike weapons officer. but all tutorial's I have looked at have used equiptment that does not look aything like the stock stuff. 1 guy managed to get a watch (sorry for not using the correct term) on the navigation map, I have spent the best part of an hour looking for it and found nothing.

Also I just suck at angles, I think the theory has me confused

here is the youtube video I've been looking at




also any general pointers for a noob would be nice

Thanks very much!
