Ok so I think that will help me to find ships, now if I can only learn to hit something
I have it set to 100% realism so am doing all the calculations myself, but I find that i'm not getting many hits (understatement) so I musn't be entering the correct data.
I find that the range meter is inaccurate in anything less than glasslike seas, as it's quite hard to line it up properly with the height of the mast while you are bobbing all over the place. That being the case, I generally get the WO to give me a the range by asking him to report and I guess the speed by working off my own. Needless to say, that's not ideal.
The problem with that is that the range seems to be one of the most important factors in your torpedo calculations as it effects the other data, like speed.
Also, it seems the only way I seem to be able to identify ships is by getting up so close that I can see the flag it's flying.
I guess like anything it takes time and i'll eventually be able to recognise them from further off, with a little help from the ship recognition manual.
