Hi Bojan,

congratulations to your successful hydro hunting job!

To answer you question: yes!

For contact speed calculation you need two factors:
travelled distance and time used to travel that distance.
To find speed we have to divide distance by time (v = s / t).
I.e. we get 926 meters per 6 minutes = 154,333 meters/mins

But we are used to km/h - kilometers per hour.
That's 154,333 x 60 = 9260 meters/hour or 9,260 km/h

SH3 doesn't use km/h but knots.
Therefore we have to convert our calculated speed into knots.

1 knot is 1,852 km/h or 1852 meters/60 minutes.

9,260 km/h : 1.852 km/h = 5 (knots)



Good hunting, Herr Kaleun!
