Ahead 1/3. Can you see the ships' "shadows" in the fog / rain / wind? If you can see them, they most likely can see you, especially during daylight hours. Have you plotted their course on your NavMap yet? That would help you immensely in figuring out where they are going to be after a set time period. What you describe with the white "X" is where your torpedo is going to go, and where it is projected to impact what you set the PK on (Position Keeper). If you see it going off at a weird angle to your boat instead of straight out and then a pinch of a bend, say no more than 15°, then you should try to come straighter in on the target, being mindful of range. There are a few tutorials on targeting, whether auto- or manual- up in Rockin Robbin's
