Oxford claimed their fourth win in five years in a supreme show of strength in the 161st men's Boat Race.
President Constantine Louloudis claimed a fourth and final boat race victory for the Dark Blues.
After Oxford's women breezed past Cambridge on their historic first battle on The Tideway course, their male counterparts made it a Dark Blue double with victory by six-and-a-half lengths.
Oxford extended their dominance over Cambridge with a 12th victory in 16 years on a landmark day for the women's boat race.
For the first time in 88 years the women's race was staged on the famous Tideway course that for so long had been the sole preserve of the men.
Hot favourites Oxford romped to a comfortable victory by six and a half lengths, as the women struck a telling blow for sporting equality, racing the same championship course and on the same day as the men.

Oxford's 11-stroke victory over Cambridge in today's BNY Mellon Boat Race was the biggest margin of victory by either side since 1973.
Cambridge's Luke Juckett lost at least five strokes when the two crews clashed near the Harrods Depositary, in the race's decisive moment.
Cambridge protested against the result, but umpire Richard Phelps threw out the complaint from cox Ian Middleton.
Losers Cambridge had a protest dismissed over an early clash in today's Boat Race which saw one rower temporarily lose grasp of an oar.
The decision means Oxford - the favourites before the 160th edition of the race - take the trophy.

Boat Race protester Trenton Oldfield has been refused permission to remain in the UK after the Home Office decided his presence was not "conducive to the public good".
The Australian, who disrupted last year's contest between Oxford and Cambridge universities by swimming into the path of the crews, was jailed for six months for his actions.
Oldfield, who was watched by millions of television viewers as he halted the race, was found guilty at London's Isleworth Crown Court of causing a public nuisance.
During his trial, Oldfield told the court that the race was a symbol of elitism and that London was blighted by inequality.
A Home Office spokesman said: "Those who come to the UK must abide by our laws. We refused this individual leave to remain because we do not believe his presence in this country is conducive to the public good."
Victorious rower Karl Hudspith has praised his team and their opponents for putting on a "real boat race" after his Oxford crew won on the Thames.
Karl was the President of the Oxford University Rowing Club when his team lost in 2012. He took to Twitter to express his frustration that the race was disrupted saying "To Trenton Oldfield; my team went through seven months of hell, this was the culmination of our careers and you took it from us".
He was joined by the current President Alex Davidson in this years crew.
Oxford president Alex Davidson said winning the Boat Race "is probably as good as my life is going to get for a while".
