#Surfing - Chasing the most challenging swells is the dream of the world's top big wave surfers, who've made an art of determining where the tallest walls of water can be found.
But now one Irish coastal regular reveals how he turned to science for his discovery of a new secret hotspot off the North West.
As Mail Online reports, Andrew 'Cotty' Cotton consulted with weather analysts and oceanographers in poring over satellite data to find the offshore sweet spot – generating waves that averaged some nine metres, or 30 feet – after the stormy winter of late 2014.
However, the Devon surfer believes the location could produce swells more than twice that size – and may even break the record for the biggest wave ever surfed as set at Nazaré in Portugal by Garrett McNamara in 2013.
Cotty's quest is the subject of a new documentary on RedBull.tv, while Mail Online has much more on the story HERE.
