Visit our store in Heeg this season!

Our store is located in the picturesque and water sports rich town of Heeg. In our store you will find all options to view and experience our navigation software and water charts. We will also help you with the installation of our software and will fix any problems you might encounter. After visiting our store you will be able to continue your voyage much safer.

It is our experience that a lot of our users prefer our help with the use of Teamviewer. With Teamviewer we are able to log on to your computer via the internet, which makes it possible to help you over long distances while you're at home or aboard without having to come to our store.

Thanks to the easy way of installation and the use of Teamviewer we experienced a lower demand for opening our store on Saturdays. Hopefully most of our users are sailing then. Because of this we have decided to only open on a few specific Saturdays during the season, making it possible to help you as efficiently as possible through the rest of the week. If you want to visit on a different Saturday, please contact us for an appointment.

The most complete water chart of the Netherlands

The 2018 edition of DKW The Netherlands is available now. Great for planning routes along the many lakes, canals and rivers in the Netherlands. Even the shallowest lakes and channels are included, starting from depths of 0,6 meters.

In the new edition a lot of changes were made. Below you will find a list of the most important changes. IF you already purchased the 2018 edition of this chart set, you can easily download the updates from the news center in WinGPS 5 (Windows) or during start up of the app WinGPS Marine (Android).

New in 2018

  • Actualised chart image based on TOP10NL (source: aerial fotos 2016 & 2017).
  • New chart for Amsterdam, based on the most recent harbour chart from 'Port of Amsterdam'.
  • New depth image based on the new Inland ENC charts, for a.o. Zeeland, Dordrecht, Amsterdam-Rijnkanaal, Gelderse IJssel, Rotterdam with Maasvlakte and the Aktewateren with Rijn and Waal up until Lobith. Other areas will follow during the course of 2018.
  • New detailed depth image of the Rotterdam harbours up until 'Noord'.
  • New depth numbers for the Friese Meren, based on depth measurements from the 'Provincie Fryslân'. Including 2 dm correction, taking into account shake off, waves, bottom slope, depth variations and water level changes.
  • Moorings for commercial shipping are shown as white rectangles.
  • Bridge pillars are shown on the charts.
  • Many changes in water sports information shown on the charts, such as buoyage, moorings, harbours, etc. Mostly thanks to user feedback.
