I saw a similar incedent occur at Lake Arrowhead some years ago. The guy pulled into his slip a little hot, and after several manuvers shifting back & forth from forward to reverse he hit the throttle to stop the boat right at the desired position. Only problem was he thought it was in reverse and the whole boat jumped up onto the dock, knocking their dock box across the dock and narrowly missed several of us on the dock. We were sitting in deck chairs at near by slips in front of his. A very scary experience to be sure. Docking is such a routine thing around the various slips on busy holiday weekends. Nobody expected what happened and it was all very sudden. Just lucky no one was injured or worse.
