Hi David

It sounds like you would like find a consensus among the Hobie 20 racers for some kind of "unoffical class" approved spinaker rig... much like the New England 6.0 nacra group did. The goal of course is to get a level playing field on the race course while providing an unofficial and unsanctioned upgrade path that any H20 sailor could join in and support. If the Texas 20's, who are pre disposed to this kind of tinkering, have landed on a Tornado chute for the boat... you might have the begining of a consensus.

One thing to keep in mind. Texel and ISAF rate spinakers by size relative to the length of the boat and the Tornado chute at 25 sq meter for a 20 foot boat is considered oversized and docked another percent (in Texel ratings at least.) USPN does not regulate spinaker size with respect to rating adjustment (although Darline has long thought that such a thing should be regulated)

Take Care
