Anyone care to share how you escape destruction when your leaving the harbor after an attack?
On a somewhat related topic, I'm curious if enemies are able to use hydrophones to detect surfaced boats? I was able to sneak up on a convoy yesterday decks awash with a green detection meter and the lead DD none the wiser, but on diving to periscope depth the meter went instantly red and the DD made a hard about to come look for me... I was in the north atlantic in this case and was able to simply dive to 210m and sneak away, but I'm curious if DD's can listen while you're technically surfaced?
Thanks,

DD's can't use their hydrophones to hear you on the surface. They rely on visual or radar contacts. When you submerge, they use the hydrophones.
If you're closing on a convoy on the surface at ahead full, you won't be heard, so you won't be attacked until you're spotted. If you dive to periscope depth, but don't adjust your speed, you'll be advertising your position on the hydrophones, and you'll attract the escorts like fleas to a dog.
Decks awash is technically surfaced. They won't pick you up on the hydrophones until you're fully submerged.
Until then, I guess your noise tends to blend in with the surface turbulation, or the sounds of the other vessels in the convoy.
