The 1800-series charts are issued mainly for smaller SOLAS shipping (Safety Of Life At Sea) and recreational purposes. The series consist of 8 atlases with an average of 9 charts (loose-leaf). The charts cover the Netherlands and Belgian coasts, the Wadden Sea, the IJsselmeer and the Zeeland delta area.
As far as practicable the 1800-series charts are consistent with the corresponding paper nautical charts, however chart scale, bathymetry and symbolisation may differ. Maritime boundaries are not charted in the 1800 series.
