Seasoned old salts reckon rowing into the cliff-sized waves at Piha is a good way of separating the men from the boys.
That doesn't take into account the four boys from Sunset Beach fast winning the respect of surf-boat crews twice and three times their age.
Pukekohe High School 15-year-olds Jack Boulton, Jack Morgan and Carl Morgan, with 16-year-old schoolmate Ryan Brash, will compete in tomorrow's Piha Big Wave Classic.
They are by far the youngest crew on the national surf-boat scene, still with three more years left in the under-19 division, but they have the luxury of knowing they've already tasted the spine-tingling swells at Piha this time a year ago.
"Last year at Piha was the biggest surf we've been in and we copped a bit of a hammering," Boulton explained. "We lost an oar and Ryan got nailed but it was good fun and a pretty good learning curve."
