The wind had picked up a bit during the night and swung the boat closer to the shore. The anchor had held well according to the GPS, but my gut feeling told me that it had dragged a few meters. Not sure.
I left my anchorage after a morning swim and continued on the Prinses Margrietkanaal past Burgum and through the Burgumer Mar, another lake-like extensions on the canal.
On the Van Starkenborghkanaal, near Gaarkeuken and somewhat unexpectedly for me, I had to go through a lock. On my approach the lock gates were opened but the signal remained red (no entry) and a Dutch announcement was made through some speakers. I didn’t understand a word, so I veered off and made fast at a mooring a bit to the side. I went over to the lock’s control tower where I met a very friendly official who explained that I had to give way to the two big cargo ships that were also approaching the lock. I could then enter last. I went back to the boat and was back at the lock gate when the last of the cargo ships had just went in, but I followed a little too early and they almost squashed me against the lock’s wall when their stern suddenly swerved off towards my side of the lock. I just managed to avoid a collision by going backwards. Lesson learned.
The lock took me up a whopping 40 cm.
Coming through Zuidhorn next, I decided to stop to get some fuel. I still had plenty but wanted to play it safe and get an extra jerrycan filled. I knew that mooring on the side of the canal was forbidden here but I saw someone else park their boat on the side of the canal and figured it would be ok for a short stop. I got the diesel from a petrol station near by, then went to town on the bike for some quick lunch. When I came back half an hour later I saw something big and neon-yellow approach my boat – Rijkswaterstaat! (Not exactly water police, but still official maintainers of the Dutch waterways.) Oh crap.
I went back quickly, unsuccessfully hoping they’d go past, composed myself, and stepped on board of Balkonia where an officer was already waiting. I explained the situation (need moa deezel!) and the very friendly officers let me get away with a gentle warning. Had I come back any later they’d have towed the boat away, they said. Phew! They also gave me some tips for the route after Groningen.
The other boat moored a few hundred meters back was less lucky. The Rijkswaterstaat ship was still stopped next to them when I lost sight of them driving away.
On the approach to Groningen I turned off the Van Starkenborghkanaal at Dorkwerdersluis (lock) and went into Reitdiep. I stopped at Reitdiephaven at the edge of Groningen for the night.
I had not gone through many locks before on any boat, and never done any single-handedly, but they turned out to be easily manageable.
