I think surfing looks like a lot of fun but I would be a little worried about sharks.
Yes, i like it surfing too, native peoples of the Pacific, for instance, surfed waves on alaia, paipo, and other such craft
Is it difficult to surf, does it require a lot of balance or skill?
Well surfers can also utilize artificial waves such as those from boat wakes, i think when you learn it its like learning to ride a bike, you cant forget it
