I love it!

Approach from 90 degrees. Set scope to 0, set 90 AOB (port or starboard), input speed, ignore range. Swivel scope until the gyro reads 0 and thats your shoot point. It's not hard.

The only difference with this game is that you can't actually see the gyro while in the scope. So you have to disable the TDC from the scope then move the heading dial on the TDC (which should really be labeled bearing) until you find the bearing that zero gyro is on, then re-slave it to the scope and put the scope on that bearing. Or just have the man on the TDC tell you when the you are on the zero gyro.

excellent

pfs!

Maybe I didn't understand it right.

But once you know speed and course (aob), it should be as easy as aim with the attack periscope to the ship, place speed&aob in the TDC, and a estimated range (very rought one, by eye) and fire.

I don't see any advantage using this method. In fact it is very uncomfortable if you are targetting multiple ships which are sharing speed&heading

Could someone explain it further? Why is it better than classic method?

It is almost the same as you do, except that by turning the heading/bearing dial until the torpedo gyro angle shows 0, you take range out of the equation. As it is only needed to correct for the straight and then curved path the torpedo takes after leaving the tube. Range is also needed to calculate the spread for a salvo on a target of certain length. But if you want to fire single shots then range is no longer a factor if torpedoes move out straight ahead.

When positioned perpendicular across the target track you get the best benefit of their broadside showing the largest angle to hit into. Less chance of a miss compared to bow-on or stern-on shots. You can orient the uboat to be off from perpendicular if you wish, but then it is best to set the AOB off as much from 90 degrees as you are from perpendicular. AOB is less than 90 if you are oriented towards the oncoming targets, and AOB should be more then 90 if you are slightly oriented towards the target course.

Once you know the target course it becomes 'easy' to position yourself ahead perpendicular of the approaching convoy. Waiting to become in-line with the first (or any) row of the convoy. With the speed, AOB and the periscope set to the lead angle (set according to those Fast 90 steps) then the TDC will be prepared to fire the torpedoes. Only differences maybe the particular torpedo depth required for a particular tube intended for a target.

The member on the furthest column in that row will pass the periscope line ( set to the leading angle) first. Don't turn the scope or it will cause the torpedos to turn to the non-zero gyro angle. Fire when it is centered on the line by it's own movement. And wait after switching to the second tube (with perhaps a different depth). Now the second-from-furthest column member will approach the line first. Again, wait for the 2nd target to be centered on the line by means of it's own movement, then fire. And so on for up to 4 column targets with your 4 tubes. The nearest one as last.

And eventually this will happen (if every thing is set up correctly).

edit: Guzz01's guide on steam explains virtually the same setup.

I made that .gif like 10 years ago.

Ok, sorry. I didn't know who made it. Probably grabbed it through one of Rockin Robbins message.

Thank you. Did not realize someone replied to my comment.
I have the Fast 90/O'kane method well in hand now for Wolfpack.
Very easy. It also has the added benefit of making it easier to gauge the convoy speed by using only one of the escorts. In my opinion, it is MUCH easier to identify an escort for my speed determination than it is to identify a merchant. Sometimes the merchants can be tricky when they are massed together and the masts and kingposts get jumbled together.
I've been sinking ships at will while surfaced by myself quite successfully with this method.
