How about I just forget manual targeting?

Weapon officers help me just fine.

Acoustics? I always fire and dive. As far as I know, once acoustic torpedoes are launched in this game, they don't change depth.

I'd love to help. But the info you are providing is fairly little to provide some directed suggestions for improvements.

My general suggestion is to track the position of the target first. So plot where he is going. Ask the watch officer when he's up on the conningtower where the target it. Plot those on the map from your current icon. From that you can measure the target speed. Distance between points divided by the time between plots. (3 minutes and 15 seconds is a common interval, but preferably longer) And the course is then shown on the map as the line through the plotting circles. (place small circles, instead of marks, to show how accurate/inaccurate the plot is) This builds situational awareness. Very important.

Speed is the most important value to know. AOB is second of importance, especially if you attack the target from it's side. Just get it set to a ballpark figure. But invest effort to know speed.

You can also measure speed by:

1. Setting the periscope to 0 or 180 degrees.
2. Then turn your boat until the periscope line is just in front of the target bow. Take the time to start IDing the target.
3. Then rudder amidship, to prevent your boat from turning.
4. Wait until the moving ship starts crossing the line. Start a stopwatch. (in game, or a real watch)
5. Stop it once the rear of the target crosses the line.
6. Make sure you know the ID of the target. Atleast in as much as you can filter it to define the target length. (alot of ships in the RM have the same lenght)
7. Now, grab a calculator: divide length (meters) by time (seconds).
8. Double the result.
9. There, you have a number close to the actual speed of the target.

But above all, keep cool. Dont rush your attack. Attack on your terms, not that of the moment. Haste is fertilizer for mistakes. And don't make him spot you. Stay stealthy by keeping your distance and use the night.
