Since april 2017 Datacharter, a Dutch company, offers the entire set of 1800-series nautical charts
for the Netherlands
as KAP-files for use in OpenCPN
These (raster)charts cover the Dutch coastal zone of the Northsea and Belgium (including the Zeeland estuaries and the Westerschelde river up to Antwerp), the Waddensea up to the island of Norderney in Germany
and the Dutch IJsselmeer and adjacent ports
Clearly these charts
are not aimed at the lucky devils who spend their days in the paradise-like tropical waters of the Pacific or Caribbean
, but more for us earthlings who have to make do with Dutch cheese and Belgian beer
The charts are available as separate sets for a specific region ("north", "south" or "south-west" or as a complete set. It is also possible to order a set of basic maps for the whole region. The advantage of these basic maps is that the buoys are omitted. That may sound a bit strange, but if you use a rasterchart and you zoom in, you will end up with "Wow, that's a big b(u)oy!" and zooming out results in "Hmm, I can barely see it...". With the basic charts you can tackle that problem by just overlaying your own set of buoys as a GPX-layer (and by turning that layer off if you don't need it). For the Dutch waters very extensive (and regularly updated) sets of buoys are available via the splendid website of "Nautin" (https://www.nautin.nl/
Prices range from .25,- ($27,-) for the complete set of the basic charts to .69,- ($75,-) for the complete set of the "normal" charts. The charts are locked by means of a personal code (and yes, that code and the corresponding charts are for nobody else but you).
Once unlocked the charts can be used on all your devices running OpenCPN
. That is your PC, laptop
or Raspberry Pi and/or your Android tablet/smartphone (with OpenCPN for Android).
