Dear Mr. Zapruder:
What a great video. It certainly shows me at my worst. Going frame by frame, I can now understand what happened with the benefit of a zoom lens from a different angle. I had totally lost the boat in the crowd for about 20 seconds starting about 7:13. The next thing I saw of my boat was it coming around the mark. I am well aware that nothing good ever happens when you can't see your boat.
Just before the offset mark Bob let me know what happened and then off to do penalty turns I went. It would be difficult for me to be any more wrong in that incident.
This video channel is great idea.
