I think I'd go for a course that intercepts the convoys course at a bit more of an angle than the 139.5° you're going for, in 12 hours you'll make 378km at 17kts so I'd draw a circle around your boat in the nav map with 360 km radius, plot a line of the targets course and head in the direction of the intersection point. That should give you enough time to set up nicely.

I could've just written: "use the map tools" right?

I'm sorry, but I don't know how to use the map tools, that's why I have to try and figure it out by hand. But I'll take your suggestions. Thanks
