Unless you’re Clark Little, you probably would rather avoid the impact zone if at all possible. It’s an impossible thing, however, and if you surf, it’s inevitable that you’ll find yourself getting absolutely punished there. Rag-dolling about underwater, getting sand shoved rudely into every orifice while your chest heaves for air and your friends surf the best wave of the day sucks. But, as we said, it’s going to happen, so you ought to be prepared for it. Koa Smith is a man who has likely spent more time in the impact zone than you have, and he decided he’d don his professor’s hat and teach a quick little lesson about the do’s and don’ts of getting your ass handed to you by the ocean.
