Admiralty nautical charts – Baltic Sea

Introduction

Admiralty nautical charts of the Baltic Sea are designed to support navigation in one of the largest and most diverse maritime regions of Northern Europe. Published by the United Kingdom Hydrographic Office (UKHO), they provide an accurate representation of coastlines, seabed features, hazards, navigational aids and major ports in the Baltic Sea.

The Baltic Sea presents specific characteristics for navigation. It includes numerous islands, archipelagos, straits, channels, shoals and complex coastal areas. Navigation can also vary considerably depending on the area: coastal navigation in Sweden or Finland, passages towards the Baltic States, navigation around Denmark, approaches to German or Polish ports, or longer-distance routes across the Baltic Sea.

An Admiralty nautical chart of the Baltic Sea can be used to study depths, soundings, hazards, rocks, shoals, wrecks, lights, lighthouses, buoys, channels and port facilities.

Admiralty nautical charts for the Baltic Sea

Admiralty chart coverage includes numerous maritime areas in Northern Europe. The different chart references available for the Baltic Sea make it possible to adapt chart coverage to the area being navigated, the planned route and the level of detail required.

The choice of an Admiralty nautical chart depends in particular on:

• the geographical area to be navigated;

• the country or countries concerned;

• the departure port and destination port;

• the planned route;

• the distance from the coast;

• the required scale;

• the port approaches to be undertaken;

• the type of navigation.

A small-scale chart provides an overall view of a large area of the Baltic Sea. A larger-scale chart provides greater detail for coastal navigation, channels and port approaches.

Navigating in the Baltic Sea

The Baltic Sea is bordered by Sweden, Finland, Russia, Estonia, Latvia, Lithuania, Poland, Germany and Denmark. It connects with the North Sea through the Danish Straits.

This geographical configuration creates a wide variety of navigation conditions. The Scandinavian coasts are characterised by numerous archipelagos and sometimes complex waters, while the southern coasts present different seabed configurations and port approaches.

A Baltic Sea nautical chart allows the main features required for route planning to be identified:

• depths and soundings;

• depth contours;

• rocks and shoals;

• reefs;

• wrecks;

• buoys and navigation marks;

• lights and lighthouses;

• channels;

• regulated areas;

• shipping routes;

• ports and harbour facilities;

• coastal landmarks.

This information helps the navigator plan a route suited to the characteristics of each area.

Admiralty nautical charts of Sweden and Finland

Sweden and Finland have particularly indented coastlines in the Baltic Sea. Archipelagos, islands, islets, rocks and channels are important features to consider when navigating close to the coast.

The areas around Stockholm, Gothenburg, Turku and Helsinki, as well as the numerous Baltic archipelagos, require chart coverage suited to navigation between islands and close to the coastline.

An Admiralty nautical chart covering these areas can be used to:

• plan coastal navigation;

• identify navigable channels;

• study depths;

• locate shoals and rocks;

• prepare port approaches;

• plan routes between islands.

For navigation in archipelagos, choosing the appropriate scale is particularly important in order to obtain sufficient detail.

Admiralty nautical charts of the Baltic Sea and the Baltic States

The Baltic Sea also includes the coasts of Estonia, Latvia and Lithuania. These areas are used by commercial vessels, ferries and recreational boats.

Admiralty charts can be used to plan routes towards major ports and coastal navigation in these regions.

Depending on the route, the navigator may require charts covering areas including:

• Tallinn and its approaches;

• the Gulf of Finland;

• Riga and the Gulf of Riga;

• Klaipėda and its approaches;

• the coast of Estonia;

• the coast of Latvia;

• the coast of Lithuania.

The chart reference should always be selected according to the exact area being navigated and the scale required.

Admiralty nautical charts of Poland and Germany

The coasts of Poland and Germany are also important areas of the Baltic Sea. They include several commercial ports, coastal areas and approaches requiring appropriate chart preparation.

Admiralty nautical charts can be used to plan navigation to and from ports such as Gdańsk, Gdynia, Szczecin and the main German Baltic ports.

When navigating along the coast, the chart can be used to study depths, hazards, channels, buoys, lights and port facilities.

Navigation around Denmark

Denmark occupies a strategic position between the North Sea and the Baltic Sea. The Danish Straits are important passages for vessels travelling between these two maritime areas.

Planning a route in this region requires particular attention to channels, traffic areas, depths and local navigation conditions.

An Admiralty nautical chart can be used in particular to plan:

• navigation between the North Sea and the Baltic Sea;

• a passage through the Danish Straits;

• coastal navigation in Denmark;

• a route towards Sweden or Germany;

• a port approach.

For these passages, it is essential to check that the selected chart reference accurately covers the intended route.

Archipelagos and complex coastal areas

One of the particular features of the Baltic Sea is its numerous archipelagos, especially along the Swedish and Finnish coasts.

In these areas, navigation may take place through waters containing numerous islands, rocks and relatively narrow passages. Accurate interpretation of the chart therefore becomes essential.

A large-scale chart makes it easier to identify:

• channels;

• depths;

• above-water and underwater rocks;

• shoals;

• navigation marks;

• lights;

• passages between islands;

• anchorage areas.

Selecting a chart with an appropriate scale ensures that sufficient information is available for each stage of the voyage.

Understanding the scale of an Admiralty chart

Scale is an essential factor when choosing an Admiralty nautical chart.

A small-scale chart covers a large area. It is particularly suitable for planning a long-distance route or a passage across the Baltic Sea.

A large-scale chart covers a smaller area but provides greater detail. It is generally more suitable for:

• coastal navigation;

• port approaches;

• channels;

• passages between islands;

• areas with numerous hazards;

• harbour entrances and exits.

For a complete voyage across the Baltic Sea, several chart references and different scales may therefore be required.

Navigational information shown on Admiralty charts

Admiralty charts contain a wide range of information useful for navigation planning and execution.

Depending on the chart reference, they may show:

• soundings and depths;

• depth contours;

• rocks;

• shoals;

• reefs;

• wrecks;

• lights;

• lighthouses;

• buoys;

• navigation marks;

• channels;

• regulated areas;

• shipping routes;

• ports;

• maritime facilities;

• prominent landmarks.

Reading this information helps the navigator understand the characteristics of the area and plan a route consistent with local conditions.

Admiralty paper charts and electronic navigation

Admiralty paper charts remain important when planning navigation in the Baltic Sea, particularly when an overall view of the navigated area is required.

They can be used to:

• plan a passage;

• plot a route;

• visualise the different stages;

• study hazards;

• prepare port approaches;

• maintain a representation independent of electronic navigation systems.

Electronic charts and paper charts can therefore be used as complementary tools when preparing a voyage.

How to choose an Admiralty nautical chart of the Baltic Sea?

The selection of an Admiralty chart should begin with a precise definition of the route.

The main criteria are:

1. The geographical area.

2. The country or countries crossed.

3. The departure port.

4. The destination.

5. Planned stopovers.

6. Possible alternative routes.

7. The required scale.

8. The required level of detail.

9. The port approaches to be prepared.

For a passage between Sweden and Finland, for example, chart coverage suited to the archipelagos and port approaches may be required. For navigation between Germany and Poland, the requirements will be different.

Example of planning a voyage in the Baltic Sea

Consider a sailing yacht planning a voyage between Stockholm and Helsinki.

The first step is to identify the maritime area and the general route. An appropriate chart can then be used to study the different areas along the route, depths, islands, channels and main hazards.

As the vessel approaches the coast and ports, larger-scale charts may be required to study channels, buoys, lights and harbour areas in greater detail.

The same approach can be applied to navigation between Helsinki and Tallinn, Stockholm and the German coast, or between Polish ports and the Baltic States.

What types of navigation are Admiralty Baltic Sea charts suitable for?

Admiralty nautical charts of the Baltic Sea can be used for:

• recreational boating;

• coastal cruising;

• passages across the Baltic Sea;

• navigation in archipelagos;

• navigation between Baltic countries;

• yacht delivery voyages;

• professional navigation;

• port approaches;

• long-distance voyage planning;

• routes between Scandinavia, the Baltic States, Germany and Poland.

They allow chart preparation to be adapted to the distance, route and type of navigation.

Chart coverage suited to navigation in the Baltic Sea

The geographical diversity of the Baltic Sea requires chart coverage to be adapted to the different stages of a voyage.

A voyage may therefore require:

• a general chart for route planning;

• one or more coastal charts;

• large-scale charts for archipelagos;

• detailed charts for port approaches;

• additional publications covering tides, currents and local conditions.

This organisation provides an appropriate level of detail for each navigation situation.

Conclusion
