[U49]

Tribal destroyer, heavy sea, it came out of the rain from 200deg, 3000m, but didn't see me... I dive immediately,

Open tube 4 and 5
I turn towards him, speed 3kts, depth 14m
I guestimate speed with 12 kts AOB is left 70, range will be about 1500m
I preset everything to fire as soon as funnel or mast are in my scope at 45deg starbord
tube 4 is selected, G7e with 3m and impact setting, speed 30

.....
I wait...
sonar says contact in 50deg
up scope
there he is
I aim.....
Torpedowaffe Achtung!
first funnel is at my 45deg mark
....
Rohr 4 (echo: Rohr 4)
LOS! (echo: Rohr 4 abgefeuert)
down scope

Sonar station is reporting torpedo running normal

...
I wait
...
40 seconds to go ..... I wait

TREFFER!
up observation scope
Range is now about 1000m, I see a wonderful impact hole (Torpedo mod) DIRECTLY under the first funnel.

OLC GUI is magic
