Is it possible to target ships using info from the hydrophone only?
What is the depth that torpedoes can be launched against targets that we are only aware of their bearing?
Can the sonarman do the target info and feed it to the WO to make auto solutions?

My answer would be maybe, but I cant imagine bothering without intermittant use of the attack
periscope. You need to have some sense of distance to target if you are to arm properly or
not overshoot torpedo range.

I've done it once, and I would attribute it more to luck that skill. I did a blind shot in to a convoy. I plotted points over time and connected them with lines to get an idea and fires a four-shot spread. Got a T3 for my troubles.

this is a much better idea if using patern running torps on a convoy

Have done it once (or twice). Got C3 dead in typical 0 visibility 15m/s at night. Knew from speed, it must be something big. While waiting for morning to finish it off, patrolling C passed @ 12kts. She got it too from ~1200m IIRC http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif
So, it can be done, but all the data for TDC must be processed manually.

The Type XXI is supposed to be able to do this.

Without S-Gear it's **** near impossible. With S-Gear (i.e. range ping ability) you just have to take bering-distance plots noting the time. Take two (or more) and you should know their course and speed. All the info you need to setup a TDC calc.

I'd been doing some blind shots against destroyers using info from sound station in my VIIB. Quite desesperate, I only get 1 kill from every 3 shoots. But it can make a world of difference, from having 3 to 2 DD charging against you.

It is possible and that is all.

Easier if you briefly have had eye contact with the target in is now using dead reconing you can use the listening gear to point the boat right and the shot better be at close range, it is like a near sighted person tries to shoot without the glasses on, it is all so blurry .....

Killing Ships using the Hydrophone

That topic title sounds like you found away to listen to ships so hard on the hydrophone that they crack open and sink http://forums.ubi.com/images/smilies/53.gif
