Gille,
We have an number of plugins that need writeups. That is one of them.

Plugins for OpenCPN 4.0 | Official OpenCPN Homepage
Chart Object Search v0.5, released 2014-10-18
Allows search of named objects on S-57 and CM93 vector
charts.
Note: After the
installation, the plug-in does not know anything about your
charts, you must view a chart at least once to populate the plug-in's database with it's content. This one time operation makes
OpenCPN slower, during subsequent views of the same chart the speed of the application is unaffected. Once the database is populated, the charts are no longer needed, so if you prefer to use raster charts, you can populate the database from the
ENC chartset and then switch back to RNC charts and the search capabilities will still be available.
