Ok, since no-one has said what speed these eels should be doing, I have done some tests in SH5 with the G7a set on "Fast". The torpedo crew skill was set to neutral.

I fired a G7a torpedo and timed it for 3 minutes. I repeated this four times.

Each time I got a consistent result. After 3 minutes the torpedo covered 4050 metres. This gives a speed of 43.2 Knots.

This speed is quite close to the torpedo's maximum speed of 44kts. Also, if I use this speed in my manual solutions, the torpedos are hitting more or less spot on, even over a distance of 4000 metres.
