Today’s leg of the trip was most amazing. The total distance from Oldenburg to Bremen is approx. 57 km. Under ‘normal’ circumstances (i.e. on a canal with no current) that would be a 9.5 hour trip at 6 km/h. Enter the tide.
I left my tight parking spot approximately an hour after high water and went down the lock onto the tidal river Hunte. The current helped immediately and the top speed on the ~23 kilometers to the confluence with the river Weser at Elsfleth was a shocking 11 km/h (compared to the usual 6 km/h).
At Elsfleth I waited for an hour for low water to pass and continued upriver on the Weser. And again, the rising tide pushed me towards Bremen with up to 11 km/h! That was somewhat unexpected for me. I arrived in Balkonia’s (new) home port after less than 8 hours of traveling.
