It will rarely be the case that these bearings taken from your ship moving at 10 kts of another vessel moving at speed (say 5 -35 kts) will ever intersect. What jaystew is showing you is how to interpolate the direction of travel and with experience doing this how to guesstimate an initial course and approx. speed for your future target. The turn towards the bearing and speed to 10kts ( I normally go to 15) are all good initial actions and certainly within a few minutes u can determine approx. direction of travel and whether that contact is moving fast or slow. If that bearing to the target is steady and it is getting bigger in your sight picture but is travelling fast then its time to get the hell outta the way lol or at least prepare a good sternshot. In general though it will be a slowish moving merchant. Jaystews description of how he guestimates the initial range is important. This is what we in the trade would call "the seamans eye", it develops over time. In game I think it is similar that the more you practice this initial guesstimations the better u will learn to determne wheter it is an appropriate target you can intercept. Keep trying is my advice but do not look for a perfect solution, remember to use the visual clues available to u through uzo/binos. Is the smoke fainter or stronger, can I now see mastheads or silohette of a ship. From what I can see you are so close to getting to grips with this, just trust your instincts a bit more. remember this will not be the information you will fire your torps on this is just initial can I intercept, which way is it going and how fast and is it a viable target for me. Keep the faith Herr Kaleun.
