I asked this earlier but I didn't see anything about it. Any reason to keep transports with your heavy ships or galleys if you aren't transporting troops? Should I be using heavies and/or gallies to hunt pirates in between wars? I'm assuming that hunt enemy fleets and blockade enemy ports are only applicable during war, or can I perform these actions against my rivals at any time?
Furthermore, related to ships. My light ships are patrolling the Alexandria trade node but it says they are generating zero trade power. What is going on here?
