For ships that can stern turn, I assume that rotation “sweeps” across the playing surface? (and the ship needs a clear path, rather than getting picked up and placed, though the Code mentions the latter under Moving)
Also, do you think the Home Island Raider ability should have been handled differently? Similar to boarding parties, I don’t think it should be the loser’s choice – either have the winner choose, or make it a random coin. Of course, if the winner chooses, then they get to see all the coins on the enemy HI (in multiplayer at least), which can be a big information advantage too.
