Something like this may help. Pulls it forward when off the wind and when you sheet in it should rotate back. There is a line on each side that doesn't show in the pic. There is a piece of shock cord with loops at each end that runs up to a piece of line that run between the bows. I will try to take some better pics next weekend. Forget about the boom setup as you don't have a boom right?
Hope this helps.
