With Leap 15.2 and earlier I used opencpn often. I use it with charts from o-charts.org and the oesenc plugin.
Currently I have Leap 15.3. I forgot to upgrade the opencpn repository,which was still at Leap 15.2, but opencpn worked fine and the encrypted charts could be used.
Last week I bought new charts. After downloading unpacking and initialising, they did not load. As the o-charts.org website indicated to check that the latest oesenc plugin is installed, I updated opencpn by chnaging the repository to 15.3
Plugin support includes wheather, tactical, annotations and tidal data. Pilot charts can be downloaded from project website at opencpn.org. Other useful add-ons may be found inside the "Download" link at at the same site.
