I was docking rental boat for the first time and was by myself this summer. Approached dock, pulled up nice and slow, put in reverse, cranked wheel and brought rear to dock, put in neutral (I thought), jumped out with both lines to tie off.
Yep, boat was not in neutral, still in very slow reverse (hadn't clicked all the way in). I'm pulling lines and the boat is moving back, had minor panic attack, jumped on board again at last second before I got pulled into lake and got things under control. Took a little ride to calm my nerves before I approached again.
I'm sure I was hysterical to watch!
