not sure what Dazzling is recommending but Cribby's Intuition gybe video of a couple a years ago is gold.
so when you say a "normal gybe" is that turning around downwind without falling off? a proper carve-gybe where you plane out is like a golf swing, lots happens in a short time so when you learn it seems to be a lot to get right. my tips:
1. hips always well over the centreline ensuring your weight is strongly commited to the carving arc. 2. bent knees to absorb chop. 3. don't let the board straighten up during the rig flip. again; hips to the inside. 4. as the carve begins, your rear hand sheets in while the front hand extends the mast (and sail) into the turn. this depowers the sail and also promotes a strong commited carve.
Once you have looked a Cribbys Vid, which is great. Find a dead flat water location and practice. Even Cribby's vid is shot at a flat water location. Its sorta like a waterskier turning around a buoy while running a slalom course. the choppyer it is the harder it is to commit your body weight to the turn and not fall in.
Mate I learnt at Port Broughton. You can stay at the caravan park and there is a little beach on the sothern end wich is sweet to rig up on. The water is usualy between knee (on a low tide) and shoulder deep (High Tide) and the water is butter smooth. And it is windy most arvos with a sea breeze. Check Wabuto Point on BOM which is about 40kms south of Broughton but gets almost identical Wind.
