Navigating the Boven Zeeschelde and the Rupel
The BovenZeeschelde is a very tidal river connecting Gent and Antwerp. The Rupel (& Dijle) connect Antwerp to Mechelen and Lier. Because of the strong tidal flow and rise/fall, both need careful planning, particularly for a trip down one and up the other. These notes are from a member living in Antwerp and well used to the journey.
Antwerpen -> Gent
- Leave (assuming you’re on the Scheldt) 1,5h after low tide. Then the trip to Gent is 6 to 7 hours at around 10km/h. You should have the current with you all the way.
Antwerpen -> Mechelen/Lier
To go up Rupel from Antwerpen leave about 2h after low tide (1,5h the absolute earliest), thus ensuring the water is high enough on Rupel.
Gent -> Antwerpen
Leave Merelbeke locks max 1h before high tide. The tide goes out a lot faster than it comes in so it will catch up.
Gent -> Mechelen/Lier
If you want to turn onto the Rupel, coming from Ghent, strongly suggest staying overnight in Wintam (through Lock), Branst (pontoon on the Scheldt) or Boom (pontoon 2km into the Rupel)
Do not go into the Rupel before tide has been coming in for 1,5-2hours or it may be too shallow / narrow.
Mind the Klein-Willebroek lock, it’s not easy when current is running on the Rupel as there are two steel posts outside the lock, in the river. Even experienced local skippers have hit these! If you wait at Wintam, it is best to re-enter the Scheldt, then the Ruplel.
