Information about the 14.5km long Canal de Furnes, the 8km long Canal de Bergues and the 21km long Canal de Bourbourg

Dunkirk is the preferred port of entry to French waterways for most boaters crossing the Channel from England or coming from other countries via the North Sea. See under ‘Dunkirk as entry port’ the description of the approach through the port and and its Canal de Jonction to the three ‘Dunkirk canals’. These lead out from the port in three directions : (1) the Canal de Furnes runs along the coast east to the Belgian border, a distance of 14.5km (and the beautiful town of Furnes or Veurne is only 7.5km beyond the border); (2) the Canal de Bergues extends for just over 8km south to the small town of Bergues, where it used to connect with the Canal de la Colme, but this waterway fell into disuse in the 1960s ; (3) the Canal de Bourbourg provides a 21km link from the Canal de Junction through to the river Aa. Formerly a key link between the port and its hinterland, extending to the Paris region, it was superseded in the 1960s by the high-capacity Liaison Dunkerque-Escaut, with the exception of the 1.6km section that was upgraded and incorporated into the latter waterway between the Colme diversion canal (dérivation de la Colme), PK 9.3, and the Mardyck diversion canal (dérivation de Mardyck), PK 10.9. For further details see under the Liaison Dunkerque-Escaut. For convenience the distances on all three canals are given starting from Dunkirk.

Dunkerque-Canals-reg

History – The Canal de Furnes is part of the complex network of wateringues (drainage channels) established since the Middle Ages. It was navigated prior to 1634. The canalisation was initiated by the Spanish, then rulers of Flanders, in 1669. The single lock was lengthened to 44m around 1818. Yet, the square lock at Jeu du Mail in Dunkerque, which gives access to the canal, was only 36 m long. The canal’s present depth was negotiated with Belgium in 1890.
The Canal de Bergues is one of the oldest canals in Flanders, its course being shown on a map dating from the 9th century. The town itself, heavily fortified by Vauban in the late 17th century, is the main attraction for boats, which moor in a dramatic location just outside the fortified walls. The site acquired worldwide fame in 2008 as the location for the cult film Bienvenue chez les Ch’tis. The local dialect and out-of-tune belfry chimes contributed to making Bergues a destination for tourists from near and far. Restoration of the Canal de la Colme would increase the number of visiting boats, but there is opposition from the authority that manages all the local drainage canals.
Work on the Canal de Bourbourg started in 1679, the Dunkerque to the Aa river. The present locks were built between 1846 and 1855, then enlarged to the Freycinet gauge. The lock ‘du jeu du Mail’ in Dunkerque is a curiosity. It was rebuilt to European Class IV standards around 1960, but there is no high-capacity link to the port basins downstream, only a Freycinet tide-lock. The high-capacity link is now through the dérivation de Mardyck, part of the Dunkerque-Escaut waterway.

Dunkerque waterways ports

The port du Grand Large has a full range of facilities including a technical/boatyard area. The Yacht Club de la Mer du Nord is recommended, as it has good facilities. Through the lock are the Bassin du Commerce, spectacularly located in the town centre, and finally the Bassin de la Marine, with more limited facilities.


Dunkirk as entry port – The plan shows the slightly tortuous route into the canals from the outer harbour of Dunkirk. Call up on VHF 73 to make arrangements with the harbourmaster. If the port will allow, leave the main ship lock (Trystram) to the right, to proceed through the more interesting old basins of the port, passing or using the services of four separate ports de plaisance. A passage north from the corner of the Bassin de la Marine leads back into the commercial basins of the port, here Darse n° 1. Turn left here to approach the barge lock that leads into the Canal de l’Île Jeanty (photo at bottom of page). From this point, an expansive basin where péniches used to congregate, it is south to the Canal de Jonction. This is where the ‘inland’ adventure begins, VNF’s Canal de Bourbourg being straight ahead. Turning left, the Canal de Jonction (part of the port of Dunkirk) leads to the Canal de Bergues and Canal de Furnes.

De- (or re-)masting will benefit from some preparatory work. The marinas at Dunkerque, whilst helpful and able to provide craneage, may not be as familiar with the techniques as the yards at Honfleur or Le Havre, so they cannot be relied on to know and do everything required. It might be advisable to talk to an experienced yard in your home country about the practicalities and the sequence – for example, disconnecting electrics; the order in which shrouds and stays and their bottle screws should be loosened and released; how and where the lifting strop on the mast should be attached (to avoid the wrongly balanced mast tipping end over end); and how the mast should actually be unstepped, lifted and laid down.


Key Waterway Dimensions

  • Max Beam: 5.05m
  • Max Height: 3.20m
  • Max Draught: 1.80m


Local Waterway Links


Navigation

Once on the VNF network, navigation is straightforward. Encounters with commercial traffic will be limited to the port of Dunkirk and the Canal de Bourbourg, especially the section incorporated in the Liaison Dunkerque-Escaut. The very infrequent movements on the other canals can lead to problems with weed and invasive species such as the water hyacinth.

Locks – There are no locks on the Canal de Bergues, and only one lock on the Canal de Furnes, situated at the entrance from the Canal de Jonction. Authorised dimensions are 38.50 by 5.05m. There are three locks on the Canal de Bourbourg. The one at Jeu de Mail  in Dunkerque (see plan) is 110 by 12m. The other two, situated on the section between the upgraded length and the river Aa have dimensions of 38.50 by 5.20m.

Dunkerque Port Lock

Draught – The maximum authorised draught is 2.20m in Dunkirk and along the Canal de Bourbourg to PK 10.9 and 3.00m on the upgraded length  incorporated in the Liaison Dunkerque-Escaut, otherwise 1.80m.

Headroom – All the fixed bridges leave a clear headroom of 3.20m above the highest navigable water level (3.50m above normal level). There are no bridges on the upgraded section.

Towpath – A metalled public road replaces the former towpath on the south bank from Dunkirk through to Bourbourg lock, then on the north bank through to the Aa. Good towpaths on the other sections of these canals.

dunkerque canals canal de la colme

We studied the feasibility of restoring this canal in 2006, but no decision is to be expected in the near future. It would open up an ideal circular cruising itinerary in the charming fenland region south of Dunkirk, and would bring many more boats to Bergues. This is just upstream of the disused lock in Bergues. dem
