From June, 1st some important changes in the traffic routing schemes of the Southern North Sea (Netherlands, Belgium) will come in place.
See the attached illustration. The
screen shot is from the actual
charts.
For users of
OpenCPN oeSENC
charts there is already an "out-of-order" extra update of the implied chart sets available to keep charts in synch with the changes.
I would recommend to keep the actual chart sets in place until end of the month, switching over to the new charts then on June, 1st.
For that purpose I'm keeping the two sets in two different chart directories.
