Rig a preventer, pole out the genoa, and sail wing and wing. Being small and light, these boats are a hand full. I don't have a spinaker or the pole for one, but I can't imagine a spinaker would be effective enough to warrant it's use. Hull speed is not that great. You're going to be slow no mater what you do. If you want pics of my setup, wait a few months (My boat is buried under two feet of snow), and PM me.
It's not a MacGregor, It's not.
