I Sail in France – English Channel

Introduction

Sailing in France in the English Channel requires preparation adapted to a particularly rich and complex maritime area. Between northern Brittany, Normandy, the Cotentin Peninsula and the Strait of Dover, navigation is influenced by strong tidal currents, a large tidal range, numerous shoals, channels, islands and some of the busiest shipping routes in Europe.

The English Channel connects the Atlantic coast with the North Sea and is a major maritime route between France and the United Kingdom. For recreational sailors, offshore navigators, fishermen, professional mariners or crews preparing to cross the Channel, detailed knowledge of the area is essential.

The “I Sail in France – English Channel” section of Nautic Way Maritime Bookshop approaches this region by destination and maritime sector: northern Brittany, Saint-Malo Bay, Mont-Saint-Michel Bay, Cotentin, Normandy, Seine Maritime, Pas-de-Calais and approaches to the main French ports of the English Channel.

A maritime area with specific characteristics

The English Channel is a semi-enclosed sea located between France and Great Britain. It connects with the Atlantic Ocean to the west and the North Sea to the east. Its width varies considerably depending on the area, while seabed characteristics and currents can change rapidly.

Tides are one of the main characteristics of navigation in this region. Currents can reach significant speeds in certain passages, particularly around the Cotentin Peninsula, the Channel Islands and the Alderney Race.

Navigation must also take into account:

• tidal currents;

• significant changes in water level;

• rocks and shoals;

• harbour entrance channels;

• traffic separation schemes;

• heavy commercial traffic;

• fishing areas;

• islands and archipelagos;

• maritime buoyage;

• changing weather conditions.

These characteristics make accurate nautical charting particularly important when planning a safe and coherent route.

Northern Brittany and Saint-Malo Bay

Navigation along northern Brittany involves a succession of rocky coastlines, islands, channels and passages affected by strong currents.

Saint-Malo is one of the main recreational and commercial ports in this part of the English Channel. Approaches to Saint-Malo, Dinard, Cancale and Mont-Saint-Michel Bay require careful preparation because of currents, sandbanks and the large tidal range.

Further west, the areas around Saint-Brieuc, Paimpol, Tréguier, Perros-Guirec and Lannion feature a highly indented coastline. The Sept-Îles archipelago, Bréhat and the numerous rocks along the northern Brittany coast require detailed knowledge of local hazards.

Navigators must distinguish between the conditions encountered during coastal sailing close to sheltered areas and those involved in passages towards the Channel Islands or the English coast.

The Channel Islands and Cotentin

The Channel Islands form a major sailing area in the English Channel. Jersey, Guernsey, Alderney and their surrounding islets lie off the Normandy coast and feature complex maritime geography.

The ports of Saint Helier, Saint Peter Port and Braye are important reference points for sailors visiting the area.

The Alderney Race, between the Cotentin Peninsula and Alderney, is particularly well known for its powerful tidal currents. Current speed and direction vary according to the tidal cycle. Passage planning must therefore take into account tidal timing, currents, wind and sea conditions.

The Casquets, west of Alderney, are another area where accurate navigation and a good understanding of currents are important.

Cherbourg and the Cotentin coast

Cherbourg is one of the main ports of the French English Channel. Its large artificial harbour provides extensive shelter and makes the port a strategic point for navigation between France, the Channel Islands and the British coast.

The Cotentin Peninsula includes numerous ports and sheltered locations, including Barfleur, Saint-Vaast-la-Hougue, Port-Bail, Granville and Carteret.

The coastline alternates between beaches, cliffs, rocky headlands and sandy areas. Harbour approaches must be studied carefully, taking available water depths and tidal conditions into account.

Navigation between Cherbourg, the Channel Islands and Brittany is a typical example of sailing where route planning and tidal calculations are closely interconnected.

Normandy and the Bay of Seine

Further east, the English Channel includes the Bay of Seine and the Normandy coast. This region is home to important ports such as Port-en-Bessin, Courseulles-sur-Mer, Ouistreham, Deauville, Trouville, Honfleur, Le Havre and Fécamp.

Le Havre is a major commercial port located at the mouth of the Seine. Its approaches are characterised by heavy maritime traffic and channels subject to tidal constraints.

Honfleur and the ports of the Bay of Seine present different navigational issues, particularly regarding available depths and access conditions.

The Normandy coast is also known for its historical and tourist sites, but navigation must always be approached from a maritime perspective: depth, buoyage, currents, weather, traffic and harbour access.

From Seine Maritime to the Strait of Dover

The French coastline continues towards Dieppe, Le Tréport, Saint-Valery-en-Caux, Fécamp, then Calais, Boulogne-sur-Mer and Dunkirk.

Dieppe is an important port for recreational sailing, fishing and ferry services. Boulogne-sur-Mer has major maritime and port activity, while Calais lies immediately adjacent to the Strait of Dover.

As the Strait is approached, commercial traffic becomes particularly dense. Merchant ships travelling between the Atlantic and North Sea regularly use this route. Navigators must therefore pay particular attention to traffic separation schemes and applicable navigation regulations.

Dunkirk is another major industrial and commercial port on the French coast of the North Sea.

Shipping traffic in the English Channel

The English Channel is one of the world's busiest commercial shipping areas. Ships travelling to and from major European ports regularly use this maritime corridor.

Vessels bound for or departing from Rotterdam, Antwerp, Hamburg, Le Havre, Southampton, Portsmouth or Felixstowe frequently cross or follow this region.

For sailing yachts and recreational vessels, this concentration of traffic requires careful identification of commercial shipping routes, traffic separation schemes and regulated areas.

Electronic navigation can help monitor the surrounding traffic situation, but it does not replace an overall understanding of the area, navigation rules and nautical information.

Nautical charting of the English Channel

Charting of the English Channel relies in particular on publications produced by Shom for French waters. Shom, the French Hydrographic and Oceanographic Service of the Navy, provides hydrographic data and nautical documents for the areas covered by its publications.

For British and international sectors, Admiralty is a major reference in maritime charting. Imray also publishes charts and nautical documents widely used for recreational and coastal navigation in the English Channel and along the British coast. NV Charts also covers several European areas.

The choice of nautical charting depends in particular on:

• the geographical area;

• the required scale;

• the type of navigation;

• the level of detail required;

• the navigation system being used;

• whether French, British or international coverage is required;

• whether the navigation is coastal or offshore.

Preparing for navigation in the English Channel

Planning a passage in the English Channel should begin with a precise definition of the route. A Saint-Malo–Jersey passage requires different preparation from a Cherbourg–Portsmouth crossing or a Le Havre–Dunkirk passage.

It is important to study in particular:

• the overall route and waypoints;

• tidal times;

• currents;

• available water depths;

• isolated hazards;

• traffic areas;

• harbour channels;

• weather conditions;

• ports of refuge or diversion;

• any navigation restrictions.

Tidal currents should be incorporated into route calculations because they can significantly affect speed over ground and estimated arrival time.

Coastal navigation, offshore sailing and Channel crossings

The English Channel supports several types of navigation.

Coastal navigation includes passages between Breton and Norman ports, sailing around the Cotentin Peninsula and trips to the Channel Islands.

Offshore navigation includes longer passages and routes connecting France with the British coast.

A Channel crossing generally requires a combination of chart preparation, tidal calculations, weather analysis and consideration of commercial shipping traffic.

For professional mariners, documentary requirements may differ from those applicable to recreational sailing and should be adapted to the vessel, its category and the regulations in force.

Major French ports in the English Channel

The main French ports and sheltered locations include:

• Saint-Malo;

• Granville;

• Cherbourg;

• Barfleur;

• Saint-Vaast-la-Hougue;

• Port-Bail;

• Carteret;

• Dieppe;

• Le Tréport;

• Fécamp;

• Le Havre;

• Honfleur;

• Ouistreham;

• Port-en-Bessin;

• Courseulles-sur-Mer;

• Boulogne-sur-Mer;

• Calais;

• Dunkirk.

This wide range of ports makes it possible to plan numerous coastal routes and provides several options for stopovers or diversion ports.

Conclusion

Sailing in the French part of the English Channel requires detailed knowledge of maritime geography, tides, currents, shipping traffic and the characteristics of each sector. From Saint-Malo to Dunkirk, via the Cotentin Peninsula, Cherbourg, the Normandy coast, Le Havre, Dieppe, Boulogne-sur-Mer and Calais, each area presents its own navigational constraints.

The presence of the Channel Islands, the Alderney Race, major commercial ports and the principal European shipping routes further increases the importance of careful passage planning.

The “I Sail in France – English Channel” section of Nautic Way Maritime Bookshop therefore approaches French navigation by geographical area, taking into account the hydrographic and nautical characteristics specific to the English Channel and its different sectors.
