(Source of excerpts (BSH S33/N24) 1/01)
Following requirements must be met to allow the official paper chart on board of
seagoing vessels under the German Flag to be completely replaced by an
ECDIS system:
To ensure safe navigation in the area of intended operation, the ECDIS must be
operated using official ECDIS data acc. to IHO Standard for Digital Hydrographic
(Special Publication No. 57 Edition 3.0), abbreviated S57 and IHO S−63.
(Item 2)

made available by the responsible hydrographic services, official raster data in
"RCDS−mode" can be used for navigation as a substitute. For these areas, how-

must comprise charts of following scales:
(Item 4)
The ECDIS must be protected against possible failure using appropriate back−
ups to ensure a safe completion of the voyage.
The current regulations allow following solutions:
