Sheet the main in, you want good flow of the telltales, but just travel out till the boat settles down. Try as much downhaul as you can first. Good luck and that should make the boat a little more stable for her. Last thing you want to do is scare her. She will NEVER get on again then. I had to add barbell weight to the boat by the mast before to make class weight. Once you learn the boat a little more it should settle down ad be easier.
