That means he is out of the competiton. I am certain that I was within the top ten 'head bangers' for the last 3 years running. I accept doing this as part of the enjoyment I get from sailing. Helmets are for whimps. "Doesn't affect me, affect me, affect me." :laugher
My brother has a Bic one design sailboard up at the cottage and a helmet is HIGHLY recommended. The older guy, Lionel Conacher (son of the great Charlie Conacher for those Canadian Sports Fans) on the left has been sailing for 50 years and the guy on the right (my brother) has been teaching sailboards for almost 20 years. This board is a rocket. Planes in about 10kn of wind, is stable, and pops up for air almost instantly. The only problem is that the 18" skeg trys to plane to the surface when your speeds get upwards of 20-25kn.
