Charley,
The factory spinnaker system for the 20 is cut very large and full. It's more of a downwind sail than a reacher like the Tiger or Inter 20. Fully sheeted, it gets pulled all the way back to the rear crossbar. I have a spinnaker setup for my H20, but want to recut it for better reaching performance. This setup is, of course, not leagal for class racing, but makes the boat useable for distance events and makes it faster overall than the Tiger, which can't match the 20's upwind speed, but still slower than the I20.
