Sweet!! I did some preliminary research on the Kiel Canal a few months ago but I didn't get all that far with the idea. There are some good sites that you have probably already visited :hmm: that provide the width and depth of the canal in meters, etc.
If I remember correctly, the canal was dredged after WW2 to enable larger draft ships to navigate the passage.
Here's hoping that you can pull this minor miracle off and a wave of map tweaks will follow!
