thank you Minute. I was talking to Pete ( him who belonga me) about my better understanding, and he was explaining how I might report the position of a contact. His example was, that if I was going on a course of 70degrees, and the contact was reported at 230 degrees relative to me ( I understand that bit now thanks to you all), I would add the two sums to make 300 degrees, which would be the true(?) bearing of the contact. Zat right? I still have to find out about subtracting ( like the skip does in Das Boot), but Pete said that if I get a sum of more than 360, I simply subtract the 360. I can follow that!
