Skimboarding, also known as skimming, is a very fun beach activity very similar to surfing. All you need is a board and some waves to do it. The only differences between skimboarding and surfing are where you start and what kind of board you have. When you surf you start in the water and paddle to catch the wave, but when you skim you start standing on the shore with your board. You run and glide on the water to get to the wave, catch it, and ride it in.
