There was drama at the beginning of the female race, with the first reset since 2012.
Referee Matthew Pinsent stopped the race in the second minute after the Oxford boat went to the Cambridge road and his oars faced each other.
Oxford could have been disqualified, but Cambridge received a third advantage of a length in the restart.
They extended that they led Coast Home, taking their account to 49 wins in 79 staging of the women’s event.
“I was absolutely clear when warning Oxford in the period prior to that,” said Pint.
“At that time, with the two arrested crews, there was no way that they were going to follow the races.
“He went through my head [to disqualify Oxford]But you can also allow after a restart to see if it affected the result of the race. In my opinion, it did not affect the result of that career. “
Cambridge Cox Jack Nicholas said: “I was holding a line and Oxford really entered that territory. Only that line and hero that line.
“We face, that’s just running. And I guess they paid the price. This is how it goes.”
Samantha Morton, Stroke for Cambridge, said: “You prepare for a shock but you never think it is something that will happen.
“You can like two hands how many times it has happened in the history of the boat race. When it happened, I was honestly with a peel. I feel stunned.”
It was the tenth year that the women’s career has organized the same day and the same course as man.
The race was a hero in the traditional course, which extends four miles 374 yards between Putney Bridge and Mortlake, although the organizers say this week that water quality was a “continuous concern.”
