A distance of approximately 14 miles (22.6km)

l’Ecluse du Chatelier is situated at the La Hisse crossing on the map
At the mouth of the River Rance lies Saint Malo on the east shore and Dinard on the west. The river is tidal as far as l’Ecluse du Chatelier which lies between La Hisse on the west bank and Port Lyvet on the east. The lock is at the northern end of the canal system which stretches from the Bay of Biscay in the south. The canal was constructed in response to the British blocking Brest and other ports in the area early in the 1800’s. The canal became operational 1850’s and remains so to the present day, with the locks being manned free of charge during the summer months.
A number of yachts every season remove their masts at Dinan, place it on the deck and proceed south through the system into the Bay of Biscay, and sometimes onwards through the Canal du Midi into the Mediterranean.
As with most canals, it was designed and built for horse drawn barges, and the first low bridge across the canal is at Dinan. Excursion vessels have when tidal condition allow made the scenic trip from Saint Malo and Dinard up through the river and canal to Dinan.
In the late 1950’s it was decided to harness the huge tidal flow resulting from the large 40 feet rise and fall and during the 1960’s the Rance Barrage was built.

BEYOND DINAN
For a number of years the wooden vedette JAMAN IV (58 passengers) has operated a sight seeing trip from Dinan up to Lehon and a little beyond. Such was the success of these trips that a larger purpose built metal craft JAMAN V was introduced in 2014.

RANCE BARRAGE
The Barrage is 800 metres stretches between Point de la Briantais on the east bank, to Point de la Brebis on the west bank.
There are 24 turbines which can generate 240,000 kW of electricity, and apart from the generation of electricity the project also provided for a dual carriage across the Rance which cut 35 km off the road journey between Saint Malo and Dinard. This brought about the end of the vehicle ferry between St. Servan and Dinard and greatly reduced the number of passenger vedettes between Saint Malo and Dinard.
The power station was officially opened by the French President General Charles de Gaulle on November 26 1966 while the roadway came into use on July 1 1967.
As a certain depth of water is always maintained up river of the Barrage it has allowed a restaurant vedette to operate every day on that section of the river and as far as l’Ecluse du Chatelier when the tide allows.
