A fleet of 250 model lifeboats have made waves in the River Thames as the RNLI held a charity Alternative Boat Race to boost the rescue institution's funds.
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.
Oxford have won the annual BNY Mellon Boat Race after a contest in which rivals Cambridge lost hold of an oar.
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.
– Karl Hudspith, Rower in the winning Oxford University boat
A year ago I was carrying my friend's body on a stretcher thinking a few moments ago he had died. That was pretty much the worst moment of my life.
You can sit around in bitterness and anger or put it past you and get back to work. That was a real Boat Race.
That was a really epic race. That was the race I have been waiting for these last couple of years. This is a very different feeling
Oxford president Alex Davidson said winning the Boat Race "is probably as good as my life is going to get for a while".
Matthew Pinsent, who umpired the race for the first time, said it had been a "busy but enjoyable experience".
The four-time Olympic rowing champion, who won the race with Oxford in 1990 and 1991, said: "It goes very quickly when you're in charge of umpiring it."
Asked if he had been concerned about security going into the race following last year's incident, he said: "Thankfully, not my responsibility. The ramifications would have been interesting - I would have had to sort out the race if there is an interruption but thankfully nothing happened."
The winning crew finished in 17 minutes and 27 seconds to cut Cambridge's overall lead to 81-77.
