I saw a cool video posted on TheNetherlands subreddit:
The video is about 2 and a half minutes, or there is a 10 minute 4K version on YouTube (link). If you keep an eye on the map in the lower right you can see where the boat currently is.
And how is the camera so high up? It is not a drone. The tugboat you see in the image is pulling a large structure, and the camera was placed on the structure. See also this image (thetimewriters.com).
Finally, if you watch the shorter video above (Reddit), you’ll see a retractable bridge at 1:56. Kind of cool.
