When you have a hunting pack after you, you must play from the hydrophone position, keeping track of all boats.
Only one boat will attack at a time, and there will be one standing watch, pinging you.
I have mentioned this tactic about 2 years ago..
What you do is race for the 'standing watch' ship while the other is attacking you.... with any luck they'll ram each other, sink each other with DC's or just be put off from their attack.
I survived about 8 hours (real time) doing this, with 3 ships after me, escaping after I broke through their 'cordon', sneaking away silent running at 1-2 knots and about 200m+ depth . I was playing at 100%+ so had no idea what happened to the ships, but I could still hear them on the hydrophone , circling my last known spot 6 hours after escaping.
It was a total of about 16 hours until I broke the surface again.
