Hey Casey. I am going to attempt to answer these based off what I learned to run the demos at Paizocon Hopefully I don't get anything too wrong....
2. The person who is taking his/her turn is piloting the ship. Anyone at that location is also on the ship. Anyone not at that location is anchored (hopefully I got that word right, I was calling it "land locked" -which was my own wording- all weekend.) On your turn, if you move, anyone else at your location may choose to move with you. Once your turn is over, the next person is now piloting the ship and so on.
Hopefully I didn't get these too wrong.
So let me get this straight...
Imagine there are 2 players and 4 locations, where both players begin at the same location. On the first player's turn they decide to move to another location and player 2 decides to stay. Now both players are on different locations. Player 1 ends their turn and now player 2 begins their turn......piloting the ship? That is ... weird.
So essentially the ships during movement only allow for extra movement on other players turns if you are in the same location an active player is when they move, you can move with them ... and that is it? Did I get that right?
