Hydro map1812 Wadden Sea East 2025

The Wadden Sea covers the Dutch part of the Wadden Sea and extends from the mainland and the closing dike to the offshore Wadden Islands, which are known as a strong tidal area. For a trip to the Wadden Sea, it is essential to have up-to-date sea charts and tide information with you.

Card format
Dutch pleasure boat maps are handy maps in 52 x 38 cm format. They contain all necessary map fragments for the respective areas in the best scales. They are printed in very clear color and feature prominent landmarks in graphics.

Update
The official nautical charts of the Dutch Hydrographic Service are reissued at irregular intervals. The side effects occur at intervals of 2 and 3 years throughout the year and not just at the beginning of the season in spring. Information about changes to the nautical charts can be found on the website of the Dutch Hydrographic Service via the Notices to Mariners.

Sports boat maps from the Dutch Hydrographic Service
The Hydrographic Service of the Royal Navy informs seafarers about shipping routes, the seabed and underwater hazards such as shipwrecks. To this end, the Hydrographic Service compiles sea charts, accurately determines the maritime boundaries of the Netherlands and carries out depth measurements. 7 sets of nautical charts are issued for pleasure boating, each covering a coastal area.

Recommendation
Those who prefer more up-to-date nautical charts in combination with a rectification service should opt for the NV charts (NL1-NL7) of the Netherlands. These are republished annually in March and are therefore more up to date than the 1800 series.
