We were fortunate to be well-positioned to respond. I was still at the helm with the engines on and the crew still up front. One mistake I made was having the crew clear the lines from the ball. We had really long mooring lines and this took some time while we drifted closer to the two boats moored behind us. I was maneuvering with one engine, which I didn't have a lot of practice with, but I got the hang of it real fast! All was fine once we were confident we weren't going to fowl the port prop. Next time I'll hold onto the ball and go find some safer space to get things sorted out.
