On a recent charter (9/23 - 10/5), I was asked to get off an apparently FCFS (white) mooring ball in White Bay, JVD by another cruiser. I had seen them in Leverick and they were travelling with another charter boat. They told me the ball was reserved and I had to leave. A heated exchange followed but he could not provide me with any proof the ball was indeed reserved so I stayed. It was late afternoon and I didn't feel like moving the boat that late in the day. Later he placed a yellow ball which had "Reserved" on it to the mooring ball. As we left the next morning, the same boat which we saw in Leverick traveling with them left a mooring on the other side of White Bay and moved to the ball we just left. Was I wrong here? Are there reservable balls other than Boaty Balls? If so, what's the process?
