Last fall I almost missed my ferry because my train up to Hamburg was so delayed that it missed my connection to Kiel, and my backup connection pulled out just as my arriving train was stopping.

I knew things were getting bad in Germany so I had planned for enough time for a secondary backup. It left on time, but kept getting slower and slower. Then they announced that due to rail works, there was a bus from Neumünster to Kiel.

At Neumünster, I instead got a taxi, which (thanks to all the taxes going to the Autobahn instead of rails, I presume), got me to the ferry with a peak speed of 150kph, and 10 minutes before loading ended - some four hours after I had planned to be there.
