Thanks for all the helpful hints guys
Tonight I had the chance to test the bow-shot theory. I was being chased (again!) by a V&W destroyer off the west coast of Ireland. I fired a stern torpedo at a magnetic setting 1m below her keel - I was a bit worried I hadn't selected a decent depth setting because the sea was very rough. Anyway, the V&W is steaming in at 15 knots and the torpedo actually impacts right on her prow as she dips into a wave! Well...she tried to dive just like my U-boat.....have a gander at these
On her way down....
It's all over....
The right bow-shot certainly delivers the goods. I love this game
