Ceitzi,

A tornado is a pretty powerful boat to be singlehanding with a spin. That being said, on the I17R, I and most of the guys I have sailed against, cleat the main ( to save the Mast!) and work the spinnaker sheet. To point higher, like Simon says, let the traveler down. On distance races on long spinnaker runs, we cleat the main, cleat the spin sheet, go to the back of the boat, trap out with foot in strap. Boat is controlled with traveler only! You may want to say a short prayer also before during this!

You could work the main also to point a little more I guess .......
