Wave shape and size can be altered from day to day, wave to wave and actually during the ride. This degree of customisation allows for all levels of surfing to take place in the same pool at the same time. Pro surfers and surf brands can design their own signature waves which can then be promoted and made available for all levels of surfers. Only the Webber Wave Pools independent hull drive system, and the inherent physical characteristics of the kelvin wake allow for anything like this degree of control over wave shape. If you can change the waves all the time, then surfers will never get bored.
