Exactly, my problem is that ASW Trawler. I hate to be so annoying, Itīs not my intention but unfortunately I am still unsuccessful and I tried 3 or 4 times again, itīs so frustrating...
I will give you details about what I am doing now...
Attempt 1: I read a good tutorial somewhere else about sonars and their range so I tried the following:
1) Up periscope to 13 meters, lock to leading destroyer, select torpedo I with dial "T", manual targeting (Manual entry toggle button) and "Target speed input" to 13 Vg / Std (good angle), I wait and shot 1 torpedo to leading destroyer, then she's going down.
2) Unlock periscope, lock periscope in the largest merchant (4800 tons as I remember), again manual targeting and target speed input, dial "S" Salvo torpedoes II and IV, if I have luck, she's going down or is getting slowing down.
3) Down periscope, I try to escape to the right (full ahead) and I dive as fast as I can to 80-100 meters. I put propellers in silent run mode. When I hear depth charges, I stop engines and wait until ASW trawler give up, then she goes to the last tanker and I take advantage, I put propellers to flank and go to periscope depth. Here itīs the big problem, the convoy is far at the right so I try to reach the merchants at 8 knots (flank) and again the nightmare, the ASW motherf... is persecuting me again even if I didnīt up the periscope. I understand, Captbones, that the reason is because the noise of the propellers but otherwise how can I reach the convoy? I am so confused
Attempt 2: Trying to follow Captbones tips...
1) and 2) the same as Attempt 1.
3) The same as Attempt 1 but instead of diving to 80-100 meters, I tried to put propellers in silent mode and aheading slow at periscope depth. It seems that ASW is confused and she really doesnīt know where I am, but again, I have the same problem because I am so behind that the convoy I canīt reach merchants in a good position. My solution: put propellers at flank and try to reach the convoy but the motherf.... ASW seems to hear the propellers and is annoying me again like a disturbing fly (midge) and I give up the exam.
Well, thatīs all. Despite I am stuck in this exam (I pretend to make a good exam to start missions), the game is amazing and I am enjoying it despite annoying destructors.
PS. I think the next time I will upload a video to youtube to see better what I am trying to do.
