Admiralty Nautical Charts – English Channel

Introduction

Admiralty nautical charts of the English Channel are designed for planning and conducting navigation in one of the busiest maritime areas in Europe. Published by the United Kingdom Hydrographic Office (UKHO), they provide the information required for coastal navigation, port approaches, coastal cruising and passages between France and the United Kingdom.

The English Channel is a demanding navigation area due to its high density of maritime traffic, strong tidal currents, shoals, numerous shipping routes and the proximity of many ports. An Admiralty nautical chart of the English Channel allows navigators to identify depths, soundings, hazards, wrecks, rocks, shoals, navigation marks, buoys, lights and other navigational aids.

Depending on the chart reference selected, Admiralty charts cover different sections of the English Channel and allow navigators to plan routes along the French and British coasts. They can be used for recreational boating as well as international passages and professional navigation.

Admiralty nautical charts for the English Channel

The Admiralty range is widely used for professional maritime navigation and recreational boating. Paper charts are produced according to precise hydrographic standards and contain a large amount of navigational information.

An Admiralty nautical chart of the English Channel may show:

• depths and soundings;

• depth contours and depth areas;

• shoals and underwater hazards;

• wrecks and obstructions;

• rocks and reefs;

• buoys and navigation marks;

• lighthouses and navigation lights;

• channels and traffic separation schemes;

• regulated or restricted areas;

• ports and harbour facilities;

• anchorage areas;

• information required for port approaches.

The chart presentation enables navigators to obtain a precise view of the maritime environment and plan their route according to the specific characteristics of the English Channel.

Navigating the English Channel with an Admiralty chart

The English Channel presents navigation conditions that differ from those found in many other coastal areas. Maritime traffic is particularly dense, especially near major ports and the main commercial shipping routes.

Navigation must also take account of tidal ranges and currents, which can be significant. A vessel's position can change rapidly under the influence of tidal streams, particularly in confined areas and near headlands, straits and channels.

An Admiralty nautical chart can be used to plan:

• an English Channel crossing between France and England;

• coastal navigation along Normandy;

• navigation along northern Brittany;

• navigation along the south coast of England;

• a port approach;

• coastal cruising;

• a route between several English Channel ports.

The chart should nevertheless be used together with the other nautical information required for passage planning, including tidal information, tidal streams, Notices to Mariners and sailing directions.

The French coast of the English Channel

The French side of the English Channel offers a wide variety of coastal configurations. Normandy has numerous ports and coastal areas where navigation requires a good understanding of depths, currents and regulated navigation zones.

The approaches to Cherbourg are, for example, an important navigation area in the English Channel. Further east, the Bay of Seine and the approaches to major ports also require careful route planning.

The northern Brittany coast contains numerous islands, rocks, channels and areas affected by strong tidal streams. Areas around Saint-Malo, the Channel Islands and Cap Fréhel require careful chart reading and proper consideration of tidal conditions.

An Admiralty chart covering the relevant area provides the level of detail appropriate to the planned navigation.

The British coast of the English Channel

Admiralty nautical charts can also be used to plan navigation along the south coast of England. This coastline includes numerous ports, estuaries, bays, channels and anchorage areas.

Areas around Portsmouth, Southampton, Weymouth and Plymouth, as well as sections of the coasts of Devon and Dorset, may require different chart scales depending on the planned route.

For a passage between France and England, navigators should select chart references that provide suitable coverage of the entire route at an appropriate scale.

Admiralty charting helps identify major hazards, traffic separation schemes, navigational aids and the specific characteristics of port approaches.

The Channel Islands

The Channel Islands are a particularly interesting area for recreational boating in the English Channel. Jersey, Guernsey, Alderney and the surrounding islands have complex coastal configurations and strong tidal currents.

In these areas, choosing the appropriate chart scale is particularly important. A smaller-scale chart provides an overview of the wider area, while a larger-scale chart provides greater detail for coastal navigation or port approaches.

Planning navigation around the Channel Islands should take into account:

• significant changes in water level;

• tidal currents;

• rocks and shoals;

• access channels;

• anchorage areas;

• navigational aids;

• port approach conditions.

The importance of chart scale

Choosing the appropriate scale is an essential part of selecting an Admiralty nautical chart for the English Channel.

A smaller-scale chart allows a large maritime area to be viewed and is particularly useful for general passage planning. A larger-scale chart provides more detail and is especially useful for coastal navigation, port approaches and areas containing numerous hazards.

When selecting a chart, it is therefore important to consider:

• the geographical area concerned;

• the planned route;

• the distance to be covered;

• the departure and arrival ports;

• the coastal areas to be explored;

• the level of detail required.

For an English Channel crossing, several chart references may be required to provide appropriate chart coverage for each stage of the passage.

Charting for English Channel crossings

An Admiralty nautical chart of the English Channel can be used to plan a passage between the two shores of the Channel. For example, a sailing yacht leaving Cherbourg for Portsmouth must take into account commercial traffic, tidal streams, depths, hazards and the various navigational systems along the route.

The chart allows the navigator to establish a general route and identify the main charted features that need to be considered. This planning can then be supplemented with tidal and tidal-stream information for the intended date and time of the passage.

For longer passages, chart coverage should be checked along the entire route to ensure that areas requiring more detailed navigation are adequately covered.

Navigational information shown on Admiralty charts

The wealth of information provided is one of the main advantages of Admiralty nautical charts. Navigators can use them to understand and interpret their maritime environment.

Soundings help assess available depths and identify variations in the seabed. Chart symbols indicate wrecks, rocks, shoals, obstructions and other hazards.

Lights, lighthouses, buoys and navigation marks also provide important visual references for navigation both by day and at night.

In areas with heavy traffic, the representation of traffic separation schemes and channels is particularly important when planning a route in accordance with the applicable navigation rules.

Admiralty paper charts and passage planning

Paper charts continue to play an important role in passage planning, particularly as a planning tool and as a complement to electronic navigation systems.

They provide a rapid overview of a large geographical area and offer an independent representation of the navigational environment.

For an English Channel crossing, a paper chart can be used to:

• plan the route;

• identify hazards;

• plot waypoints;

• visualise traffic areas;

• prepare a port approach;

• obtain an overall view of the navigation area.

Paper charts do not, however, replace the other sources of nautical information required for properly prepared navigation.

How to choose an Admiralty nautical chart of the English Channel

The choice of chart depends primarily on the type of navigation being planned. A chart intended for an English Channel crossing does not necessarily meet the same requirements as a chart used for entering a port or navigating close to the coast.

The main criteria are:

• geographical area;

• planned route;

• chart scale;

• level of detail;

• ports concerned;

• type of navigation;

• distance to be covered.

It is also important to check that the selected chart covers the entire area required and provides the level of detail appropriate to the intended navigation.

Example: planning a France–England crossing

Consider the example of a sailing yacht making a passage between Cherbourg and the south coast of England.

The first step is to identify the charts covering the overall route. The navigator then checks shipping traffic areas, hazards, depths and the main navigational references.

The route must then be assessed in relation to tides and tidal streams. Departure times can have a significant influence on the vessel's progress and on the route actually followed.

As the vessel approaches the British coast, a larger-scale chart may be required to prepare the arrival in the selected area and the approach to the port.

This example illustrates the importance of having chart coverage appropriate to each stage of the passage.
