I am not sure what you mean, Dustyboats, but the map contacts will disappear if you zoom all the way in, as they are contact reports, not ships you are actually seeing. When you get close enough, they will appear in their actual position, and not disappear. (Unless weather is bad or you are submerged)
Also, the tail of the contact indicates what course they are on, so the there will be no contact if you go directly to the indicator on the map, since you will probably get there hours later. The thing is to go flank speed in a paralell line, and then turn sharply so your nose is on a 90 degree course to the intercept point. Use the ruler to calculate distance, and try to get within 3000 metres of the intercept point. Then its just a case of waiting with the finger on the trigger.
Sorry if this is overexplaining, but I dont know what you mean yet.
Oh, and welcome!
