I have been surfing since I was 10 and now I am teaching my son Connor to surf. I have surfed some waves in the 10-12' range and those are big waves. When you get into the waves that break at Maverick's or Ghost Tree, you are on monsters that would scare the devil out you. Respect for those that can do that and survive. Here is a collection of some of the gnarliest waves on the planet. Cowabunga!
