A good tip given to me by Andrew Bergman at Drews was not to snatch at the handle at the back of the ball, but to drive the outside hip through and let the ski tip come right under the line or further before connecting the outside arm back to the handle. In fact he said ‘imagine you are trying to ski almost back to the whitewash with only your inside hand on the handle before reconnecting’. Try it. It’s incredible how much speed you can carry around and through the turn using this tip and it really smooths out the finish of your onside. Obviously, you need the width coming into the ball and a tight line off the second wake to enable this, otherwise you’re going to ski straight at the ball and way down course pretty quickly. As AM always said, finish the turn AT the buoy, not after it’
And incidentally I’ve always found that moving the front binding back one hole helps the onside turn…
