Check this footage out Cloud Break at 12ft+ if it wasn't windy it would have been 15ft+ easy. I'm sitting in the Namotu Hunter boat at the 19 second mark ( Help Me Please Mr Wizard ) Only two surfers out Reef McIntosh in black wet-shirt at the 28 second mark and Anthony Walsh. Then Kite surfer Ben Wilson catching the wave of the day at the 29 second mark. I went surfing & fishing with Ben just about every day. I'm not into Kite boarding, by the time I go Surfing - Downwind Paddling and Fishing I can't fit anymore ocean sports in.
