my compilation of useful to know stuff

I'm pretty sure it is the closest harbour, not the harbour where your ship was built. And there is a max maintenance distance as well, moving fleets longer away than this will not increase the maintenance.

Correct. It's your ships' distance to the closest friendly port (owned by you) that determines its support costs. (It's one reason why Sicily is such an attractive target for Mediterranean naval powers. ) I want to say the support costs cap out at 80 florins per ship/year, but you probably shouldn't quote me on that as it's been a while since I checked.

I'm not sure what's going on with your other issue, Faction Heir. I don't think I've played vanilla MTW since VI came out back in 2003, so I can't really remember whether or not the agent bonuses in 1.1 work in those two provinces.

Now that said, the Inquisitors don't really need a valour bonus -- believe me, I know. However, it's indeed unfortunate that you're unable to get Syria to turn out those lovely v1 assassins, as they can be very useful.
