I was thinking the boat shifted in what looks like a sharp curve when he turned/braked coming down the road in the background because the winch was'nt locked or it unlocked and he looked in the mirror to see his boat moving around TOO LONG and BOOM! hello lightpole and 20' Bayliner. I missed a neighborhood offshore fishing trip in the 70's and on the way home ( the captain ) ran in wet ditch on 70 down east at night and stopped abruptly!!. His 23' flybridge boat ran over the truck w 3 of my friends sleeping in the bed, luckily nobody was injured, the big boat stopped 100' ahead of the of the truck. It was a Ford!
