After reading your posts I've decided that there will be 3 boats per kingdom, up from 1. However, I've changed the maximum per boat to 4. This means that up to 12 kingdom members can join the battle. If I get enough feedback, the "2 members per boat" will be dropped, and the amount of boats in the battle raised.
Still not sure about the time though. I was thinking this Sunday at 9:30am Australian Central Standard Time (Saturday 7pm EST) but this date is not yet confirmed. I don't get up early on my sundays
I'll keep updating the first post rules as i go.
