Yes! Finally. Today I landed Shakas on flatwater, I mean totally flat. i didn't know how to initiate the carve before, but suddenly it just hit me, going 5.2 semi-powered. It's just all about the sail, swinging it to help the carve and then sheeting it in while airborn. I landed one totally sick and big one in front of Johan, loosing the slide mid way round though. The next one was not as big but all slidey, totally loosing the fin at landing, spinning round instead of pushing. This is by far THE sickest move in windsurfing.
Johan almost landed his Forwards on flatwater too.
Stay tuned for pictures from my underpowered 5.2 session a few days ago, it's sick, you betta believe it.
