Best 'actual' snapshot & long-range shot techniques?
There is a great thread on here: http://www.subsim.com/radioroom/showthread.php?t=229792
which details authentic methods the U-Boot commanders used. However, in both cases, it relied on getting well ahead of the convoy and lying in wait; the gold standard ideal. However, what - if any - where the techniques used for shooting at long range or snapshots where you're basically unable due to circumstances to get any real data or recognition, but need to quickly fire and hit? |

Enter the Ausdampfverfahren! I outline that method at the end of the document but basically, you achieve a constant bearing to target (I.e. collision course) over a few minutes, note that bearing and own speed and his eyeballed AOB, and derive his speed: Own speed x sin(bearing) / sin(AOB) The bearing change method over a minute is another option, but you need a range at first bearing as well as the other info as above, in which case simply guesstimate the mast height (30-35 is a good avg I think). These methods are a check on the data gleaned from overhauling in my tutorial, but they can be used on a standalone basis in a pinch by all means.

Long range shots were never permitted according to the uboat commanders handbuch. Very frowned upon.
It was not until late war when the acoustic and pattern running torpedoes were brought into the war that a uboat could take long range shots. |

The crazy ranges were rare but the my point was that pure estimation was used very frequently. A lot of the longer range firing reports are probably boats shooting outside of the escort screen later in the war.

I seem to recall, maybe from SH4 days, of a technique of setting the TDC/PK so it fires dead straight and then using a quick mental arithmetic trick turning the ship and then firing.
Does this ring a bell or is it a fragment of a dream I had? |

i rarely bother with drawing all over the map other than a target course line so I can set up a fast 90 attack, in which case exact range doesn't matter anyway. Firm believer in the kiss principle.

The “range doesn’t matter at zero Gyro angles” Is such an important thing, with newbies I’ve really been trying to drive that home.

I just keep out of their visual range, while keeping them barely in mine, whatever the range is (clear, overcast, doesn't matter). Easy enough to guesstimate their speed/course by paralleling their course for a few minutes. Can fine tune it later if desired, but that will work just fine for setting up a fast 90. Or longer if a wolfpack is being called in; I've covered conveys for hours/all day game time several times while waiting for the go ahead. Early war of course; radar can throw a wrench in a surface overtake.
