G'day Katardy
There are about 10 Windsurfers in the Yeppoon/Rocky area. We would all be keen to give you a hand and some pointers. Unfortunately, no one does formal lessons in Yeppoon.
If there is plenty of wind around on the weekend or sometimes during the week, say 18knots plus, I'm sure you would find a few of us (generally after lunch) launching from the sailing club located on Main Beach.
Feel free to approach any of us on the day if you have any questions and I'm sure any of us will be able to assist.
Have fun!!!
