That's an incredible amount of micromanagement and hassle. To cover the British Isles you need something like 3-4 separate fleets in different ports, and that's a relatively small area. If you start colonizing, that's another small fleet that has to cover every few sea provinces. It literally impossible to amass an actual navy for combat, because you have 15 different 3 ship fleets preventing pirates from spawning everywhere. That's just impractical and really takes away from any colonial/naval aspects of the game. It's an a poorly implemented aspect of the game that comes as a hit to the actual gameplay.
No it's not, and it's not 3 ship fleets, it's 1 galley in a fleet.
It requires no micromanagement because as long as attrition is at zero the ships can sail forever, you can keep it at 0 by going from port to port, not ocean province to ocean province. If the ship is in port at the beginning of a month it restores itself from whatever negligible damage it may have received. This is especially so if you choose the national idea that allows ships to heal in coastlines.
And for the British Isles you need 3 galleys. 4 if you want to include the rebellious Irish. That is 4 ships when the limit is 30+, not only does this free up carrack spots, but also Cogs. A sea based empire needs it's cogs, and it can't have them if you are racing around with extra large ships hunting down pirates when there is no need. Pirates that spawn from spies are another matter entirely, but normally occurring Pirates are a scourge of your own making.
Make the ships patrol on their own, from one port go to another or to the adjacent sea province and then you don't have to worry about pirates any more in that area.
In the latest beta it might require a ship in every port :rofl: which to me just seems silly unless of course they are Islands with no neighbors in sight like Diego Garcia
If you don't believe me try it out for yourself, when you realize all the time you've saved and all the ships you've freed up I'll expect a generous donation
