No book or DVD can really teach you to surf, but all the water time in the world and you can still miss out on the fundamentals if you're not out with more experienced surfers. If your about to head into the water for the first time or a beginner struggling with your board, or the politics of the lineup a few quid on a good book or movie can save alot of grief and make learning to surf what it should be, a totally pleasurable journey...
