I built shipyard in my region couple of days ago.
In today region report I got info: "2 new navies are ready. There are now 3 available."
So all I managed to notice is that shipyard is producing navies.
Is there any other use of shipyard and what is the actual use of navies?
Wiki says about shipyard: "Builds and repairs warships, used to patrol sea zones. Shipyards can be built in cities, townslands, strongholds and woodland regions.", but I searched all options and I can not find where can I recruit/repair warships or assign them to patrol sea zones. - Is it possible at all to do it manually or it is all automatically?
