Jeff,

I know where you are coming from, I am one to experiment on boats. I put a N5.8 rig on a N5.0 with 10' rack for the Ruff Riders years ago. The concept was fun, but needed more boat for the horsepower. I think what will happen is you have an extremly overpowered boat. The boat can only handle so much power and then heals over. The only time you will go faster is in real light air and off the wind. Then the trick of sweeping the shrouds aft and out enough to handle the loads, with double backstays. I am not sure if the ARC rig can handle the weight difference of the boats. The Viper is light, but it carries much more momentum than a cat. As rigger with racing and cruising experience on cats and monos, one realizes the loads each of the boats provide. I am thinking about adding amas, my P-19, on my Merit 22, an old MORC design. There would have to be some upgrades on the rig, but the idea is basic. I am interestered in your idea and if you go through with it, please keep me posted...

cheers...
