The annual Belgian National Championships are as ever on the first weekend of October. This is a friendly event fuelled by Chimay beer!
The venue is under 3 hours from the channel tunnel so easy to reach.

If you are a regular you know the form.
Registrations are open: https://www.sneh.be/les-regates/calendrier/#!calendar
Just click on the event and you'll be transfered to manage2sail.  It's easy and fast if you're already registered against manage2sail, otherwise it takes a little bit more time but when it's done, next registration is piece of cake.
At the moment, there are 8 boats from Belgium and I'm expecting 5 more.  One from France has already confirmed by mail and the organisers think they will get 4 or 5 more boats from Paris area.  
So act now!
