News 2017 – We have received reports that the upper reaches of the Rance has not been dredged this winter and so silting is expected to increase. Vessels should keep well inside of the buoyed channel.


Port of Lyvet – with lock at top of picture – picture by

We visited by land in 2016. There are no signs for the visitor pontoons. They used to be pontoon D which is 2nd from the top of the picture (the bottom pontoon does not have a letter). We are informed there are not specific visitors moorings at Lyvet most of the time but Giles fits boats in as and where he can.

I enquired at the marina office and received the following message which translated says “visitors usually call before or take a position and pass the captaincy just after. If I see them arrive, we welcome them but unfortunately, I ‘m all alone and cannot be everywhere.”

This is the passage to the lock shown at low tide. Holding area is the pool at the front of the photo


It is well marked. The passage is narrow but well marked. The strange structures are for fishing.



The Chatelier lock


Chatelier lock opening – note holding area and bridge swivelling

Stan says “The marina at Le Chatelier (actually called Lyvet) is not restricted by length but by draft. If you draw more than 1.7m you can’t get through the lock and there are shallow parts all along. To get to Dinan you MUST draw less than 1.5m.”


When they let the water in, there is quite a bit of turbulence so be prepared


When it is full, peace is restored. Note Lyvet “marina” on the left as you exit the lock

The office at Lyvet is good and the facilities are clean. There are a couple of showers and a couple of toilets and that is it.


The marina office is on the left and the facilities on the right.


A website (…) suggests min depth in marina 1.7m but no indication of how up-to-date that is.

A fellow boater was delayed going both ways through the lock by over an hour by a Vedette and a bunch of kayakers so don’t bank on going through when you plan to.

Le Saint Patrick – Bar, restaurants and does take away Pizzas. Great fish and chips! Visited in 2016 and great Irish service and food. Closed on Mondays and Tuesdays and when they go on holidays out of season.

Bread-The bakers van bread service stopped a couple of years back when the shop at Pledhien changed hands but they do use the Gourmande as a depot in the summer months. The baker in Vicomte is now a Bistro.
