The told me to take mooring #19. When I got there, there was another boat on #19. I saw an empty mooring (#27) and called the marina to tell them 19 was occupied, and asked if I could take 27. The marina said 27 was okay. Late in the afternoon after we got everything packed up for the night, the private owner of #27 showed up and told us to get off. Called the marina and they gave us a different mooring, but it was a major inconvenience to get everything untied and move at the last minute with the mooring owner circling and looking very angry.
