I used to ride at the one in Durban called the Wavehouse. One of the only double break setups in the world and they also had two training slopes. Great fun but not easy. Last time I saw it Matt Lammers (ex-SA wakeboarding champ) was doing 720 backflips on it.
Rides very similarly to snowboarding because its finless.

will fix it up for all
