Since the late 1960s (when Gordon Clark found the optimum formulation of polypropylene foam), most of the surfboards in common use have been of the shortboard variety between 6 and 8 feet in length, with a pointed nose and a rounded or squarish tail, typically with three skegs but sometimes with one or two. Surfers generally find a shortboard very quick to maneuver compared with other types of surfboards.
