accuracy in manual targeting mode

[Pisces]

I do not remember my overall accuracy, since I am usually submerged trying to dive away, and no freecam or eventcam to tell me. But if I do not rush myself, and stay calm, I hardly ever miss.

The most important factor is target speed. This should be measured at about a quarter knot accurately (average plots over 4x3.25=13 minutes, that 'll do), especially if you fire at longer distances. You can play around with the target speed dial and see where the periscope ends up when you make the gyro dial exactly 0. (setup AOB=90 when periscope is at 0 or 180 for aft-shot before that) Then compare this difference (like for 8 and 9 knots) with the appearant size of the target in the scope. (easier said than done while it is moving in front of you)

The length of the target plays a forgiving role in this problem. Distant targets look smaller in degrees making accurate target speed a neccessity. While longer targets are obviously larger in degrees.

Also, having your torpedo tubes allready open well before firing is also important. The delay of opening the tubes has caused many misses among fellow Kaleuns (here).

Aside of the target 'size' issue, the range of the target is not important when the gyro angle is 0. So, if the situation allows itt, point your boat at the intended impact point.
