Hi Glen
As Ted says, you're in the right place... there are paddlers all over Cape Town ready to lend a hand.
Depending on where you are (northern or southern suburbs) I'd recommend visiting Brian's Kayaks (Paarden Eiland) or the Paddling Centre (Fish Hoek).
You'll find demo skis and friendly faces in both places.
I'd strongly recommend having a few sessions with Dawid Mocke's SurfskiSchool as well - they provide all the gear and will a) get you started correctly and b) give you a chance to see if you're going to like the sport. (Of course you will!)

Happy paddling - hope to see you on the water!
