Mizi,
You have to hold on to the righting line and get behind the balance point. It has been a long time since I actually had to do it that I can't visualize where I was standing. The balance point is the front pylon so I may have just stood on the rear of the tramp. I was given this tip in a Hobie Fleet meeting and only did it a couple of times. It was easy to do. The last time I turtled was about 10 years ago.
