A good amount of luck helped. No wiz here

I do like this tactic of running through the convoy from astern, at a slow overtaking rate and keeping convoy course. I think it gives some good control, e.g. if you come up on an escort, you can just back off, alter course for a bit and come up again still on convoy course, but on a different track to avoid the escort. Even when in the middle of the convoy, I was finding that with the visibility so low, a small course and speed change would take me out of harm's way (most of the time). Give it a try
