The wave curls – whip-fast and flawless; it goes on and on and on.
Inside it surfing in the barrel of the wave – the feeling – the high that surfers yearn for – is Nat Young an American pro-surfer ranked ninth in the world.
Above him a drone films his run – 10 seconds – 20 seconds – 30 seconds.
It was the longest barrel of his life.
Young had never surfed a wave like this before.
Yet this was 110 miles from the ocean in California farm country in a specially constructed exquisitely engineered freshwater pool.
And it was perfect.
‘It’s an awesome feeling’ Young told the Guardian.
The pool was built by 11-time World Surf League champion Kelly Slater who for 10 years had been focused on an idea that many thought was impossible – building a machine which could reproduce the ideal wave and create it on command.
