If CM93 take a (careful) look here: https://opencpn.org/wiki/dokuwiki/do...s:cm93_offsets

CM93 shows correct position if you zoom out to a scale smaller than approximately 1:50000. At the large scale you are showing CM93 is based on chart BA1812 which is very old.


This chart is not suitable for OpenCPN's CM93 offsets. This is explained in the notes printed on BA1812 and repeated in CM93.


The best thing to do is to use a sat pic from SASplanet to create an mbtile chart-overlay that can be displayed in OpenCPN. You can do this directly or use a tool such as Sat2Chartif(windows only).

Depending what you need exactly (and without covering the same area at the same scale) there are some S-63 charts available for that region.
