1. When I am aiming to the ship using a hydrophone with a direct direction and asking my crew for a report, they tells me about another ship that is 40 degrees next to it. There are no other ships in that direction. It's a bug?

2. How to estimate (set) the enemy convoy course without map update?
There is no problem with a single target when I'm using hydro and sonar but when there is more ships there then I have a problem that I mentioned before.

3. Where is torpedo best aimed? Directly into the middle with hope of breaking the construction?
Is it sense to hiting the same place many times? Does the draft of the torpedo change enything? If the keel is rounded, does it affect the torpedo reflection?

4. Are there other methods of manual targeting than TDC + mast height and Dick O'Kane method?

5. How effective are passive acoustic torpedoes? Are they best?

6. Does the enemy use torpedoes against you? If he does, how to deal with it, exactly with acustics?

7. Is it true that the enemy can not detect you using radar before 1943?

welcome, niceguy.
if you are playing the Stock game (not vanilla ) there are some techniques you can use to improve these issues but some of them are unexpected features.


the sonar detection/reporting thing is an unexpected feature. you can listen and hear ship-noise for direction but to get range you have go active-sonar and, personally, i rarely use active sonar. run silent, son. the disconnect between what you hear at the sonar station and what appears in the message text box is a known feature.



for tracking enemy singles or convoy, use the longer pencil to place an X on a detected location. over time (a few minutes) you will have a series of X's which you can then connect with a line from the ruler or protractor and determine a course of advance.



torpedo placement is always a topic of discussion. in real life, captains aimed for the bow or the stern because that is easiest place to cause the most damage to a merchie. lots of reading material on this. in the game, by default, the autotargeter shoots for the center of the target. if you are new to this thing, my advice would be to shoot for the center of target and as you evolve and develop your techniques you can figure out how to start shooting the propellers off the enemy.



targeting has many theories. i, myself, use autotargeting but there are others here at Subsim who will weigh in on that subject.



the US acoustic torpedos during WWII were not very effective. here is some reading for you.

the IJN will not use torpedos against you in the stock game. bombs, shells, etc but not torpedos. there are mega-mods you will encounter as you evolve here at Subsim that will have IJN shooting torpedos at you but not in the stock game.



if the enemy has radar they can and will detect you. assuming you are playing the US side vs the IJN, then it is a historical fact that the IJN bought into both radar and sonar a bit later than the US. so, the 1943 thing may or may not be correct...just know that if they have radar or sonar it will be used.



there will be others who will offer help on some of these topics. you should also do some reading (offline) to get an understanding of the background on some of these things.
good luck. and good hunting.
