Official video shows the dramtic moment Sir Ben Ainslie's yacht crashed into the rival Japanese boat at the America's Cup showdown in Bermuda.

Both vessels were damaged and the penalty incurred by Land Rover BAR was the only blot on an otherwise successful day for the Portsmouth-based team. The collision happens around 50 seconds into the official video of day 1 action.
