Thanks mate, just figured out how this method works, It's taken 3 hours thinking about it and trying to copy out the map as you draw it felt like I was

for a long time. But I did it

and am now off to try it for real. Thank for this I've been having real problems plotting courses by visuals, now all I need to figure out is a rough range and I can plot an intercept

.

Again thanks

edit: hold on a moment

! what the hell do you move the U-boat for

?? it dosen't apear to be neccesarry to calculate the course

??

edit edit: OH NICE

! The theorietical fourth bearing from your original position intercepts the actual contact bearing at your new position giving you the course and distance of the merchant from your U-boat rather than a parallel one. Brilliant

.

Edit your narrative slightly, give step by step diagrams, and get the moderators to sticky this thread, this is fantastic!
