Going thru our first lock on the Danube

Wanted to try something a little different. This is a series of photos that Belinda took and has shared with me. I've selected all 25 photos and then created this link and I'm hoping that it will work without me doing any more than that. This is the Greifenstein lock about 20km upstream from Vienna.
 

Now going back to edit this post (24th April). This was at 0740 in the morning doing some work and took this shot for the guys at oobe.
Left at about 0900 to head off to Vienna and go thru the lock on the way. Feel free to look at that link above which shows the whole series as we go thru. At one point the current was almost 10kmh so I took this shot.
And then this. Lots to look at here. The tablet is showing we are doing 17.9kmh Speed Over Ground (SOG). The chart plotter is also 9.5kts SOG (9.5kts * 1.85 = 17.575 kmh so it's about the same which is a good thing) and it is showing a speed of 4.5 kts (8.325 kmh). What this means is we are moving thru the water at 4.5 kts but our speed over the ground is 9.5 kts so therefore the water is moving at 5kts or 9.25 kmh
End of the day in Vienna with Belinda watching the cruise ships going past.
