I was patrolling BF21 earlier today, just north of the Isles of Scilly. I was quite tempted to go through the Irish Sea on the way home to save time, but in the end returned the same way I arrived, around the western side of Ireland. I might only be playing stock SH3 (at full realism minus external cam) but I'm being really careful, in preparation for GWX.

I saw enough destroyers south of Ireland that in the end I didn't even want to think about the North Channel in the end!
After reading your first post I'm glad I took the long way around
