We have created a separate group of pages for western and southern Brittany. Should you have any information, advice and photos, please do send them to us.

We had a great trip to Southern Brittany in 2017 and I wrote a blog of the trip which I hope you will find useful. Please click on the following link.  Blog for the Trip to Southern Brittany

Do visit JimB Sail for further information on the west coast of Brittany www.jimbsail.info/tidal-europe…

This is the site for Southern Brittany www.jimbsail.info/tidal-europe…

This is good pdf of all the marinas in the area www.nautisme-finistere.com/IMG…

The trip involves passing through the Chenal de Four and the Raz de Sein.

The slack water for the passages are as follows:

Chenal du Four – High water Brest -1hr to +30mins and High water Brest +5.5hr to 6hr
See www.sailingalmanac.com/Almanac… with useful marks

Raz de Sein – High water Brest -1hr and High water Brest +5 to +6hr hours. Slack water lasts for around 30mins

In 2017 we went through (South to North) at 2 hours before LW (coeff 54) i.e. 4.25 hours after HW and it was flat.

We have included Loctudy and Benodet. Any other marina information would be appreciated. We have been told “take a tip and steer clear of Port Haligen on a weekend, it’s MANIC!!!!!! Rafted like you have never seen before!!!”
