Hi TD
I've got a complete rig (5.5 freeride sail) you can borrow until you decide if WIndsurfing is for you. You'll have to try to get yourself a board though. Something in the order of a 150-200L board until you can re-learn the basics - try to borrow one. Give me a ring on 0466 104586 if you want to borrow the rig.
Purchasing is mostly online now days. The market here is micro. I reckon maybe 50 sailors in Adelaide ?... which makes the sport pretty special and niche
