Hi, thanks Trevally, you have succeeded, at least in part, where all my maths teachers failed. I can now follow a procedure in trig... but I still don't get the right result.

Using your four bearings tutorial I have checked, double and triple checked every stage of 'The Hunt'. My three bearings are all plotted to within a tenth of a degree of 56, 61 and 68 degrees. The compass parallel lines from bearings one and three are good and cross bearing 2 at the same place. It all goes wrong when I draw the line through the intersections. Your tutorial states 'as you see the ships true bearing is 206 degrees'. Not on my map, I'm afraid. I'm consistently getting 198 degrees. Any ideas where I'm going wrong?
