In this instance skurfing is used to describe a popular surface watersport in which the participant is towed on a surfboard, behind a boat, with a ski rope. Originally created by a surfer named Tony Finn in the mid 1980's
Skurfing is highly popular in the state of W.A in Australia and in many other places in the world. However, it has yet to take off in the U.S.
Unlike most other watersports where the participant is towed, Skurfing is not a professional sport and has no official competitions, it is a freestyle sport with highly individualistic style and form. There are no defined styles or conventions rather it is about personal style.
Skurfing is considered by many to be a precursor to wakeboarding, as the skurfboards evolved in the late 1980's into compression-molded skurfers (aka "Skiboards") then eventually into the twin-tipped Wakeboard.
There are two main styles of skurfing, the noseriding style, mostly used by people who surf on a longboard. The alternative is with cutbacks, carves and other turns. Some people even get air over the wake.
A new style of skurfing has recently emerged in the sport where the fins are removed from the bottom of the board. This finless style requires more balance and finesse than having the fins attached. Not having fins limits cutbacks and carving, but allows the rider to spin the board around in a 360-degree rotation.
