Paddling Into Big Wave Mullaghmore

In the fourth episode of Threading Edges we check out paddle-in surfing at Mullaghmore.
For a long time it was thought impossible to paddle into Mullaghmore. It was just too big and the conditions too extreme. But then Fergal Smith and Tom Low, inspired by the fearlessness of boogie boarders at the break, pulled it off.
Now that the code has been broken and with advances in board design it is down to the strength and will of the surfers that ride this incredible big wave to push the limits even further.
How big is too big to paddle Mullaghmore?
