Impossible to determine without knowing its starting speed.
Starting speed: 0 Knots.
Can you give an instance when this is _not_ the case? Every time
I've started a trip I've experienced a starting speed of roughly
zero knots. give or take.
When you have to back out of the slip! -0.25 knots!
What was the vessel's velocity relative to the geodesic coordinate frame
when it _began_ moving in reverse?
