1 shot - 1 kill

[the.terrabyte.pirate]

I've read the glorious tales of success of that (choke) magnificent captain Balz and his desire for one shot - one kill. I'd like some tips on how to actually achieve that?

Brag's website talks of sinking c2, c3 and Victory cargo vessels with one torp between the bridge and the smokestack, but does not specify if it's an impact or a magnetic shot. He mentions that he thinks that it might be striking the fuel bunker. Can a magnetic shot under the keel beneath the bunker achieve the same result as an impact shot directly to the bunker itself? I'm also not sure if it is still true in GWX 2.1, and whether this tactic is true for all large vessels. Has anyone tried it yet?

Brag also mentions a guaranteed, but slow, sinking by targeting the ship at the foremost mast in GWX. Once again, does this still hold over to GWX 2.1?

Others have mentioned a guaranteed sinking caused by targeting beneath the guns on large warships. Are we talking impact or magnetic? Same issue as the fuel bunker on the above cargo.

I'm aware that at the perfect firing position, vulnerable spots of the ship appear on the recognition manual. Targeting these spots in stock shiii would produce an almost catastrophic sinking, but I remember reading that the new damage models and sinking times have made these vulnerable points less of a guaranteed sinking.

Does shiii accurately represent a torp induced hole at the front of the vessel leading to an increased rate of flooding caused by the pressure of the forward momentum, or will a hole anywhere in the ship produce the same sinking model? Basically, is there any real benefit to targeting the bow of the vessel rather than the stern?

If you're aiming for a one shot kill, how are you setting up? Magnetic for max damage? Impact to directly target a vulnerability? What depth? Where to target? What tactic has been successfull for you? Opinions and discussions please.
