Forrest, welcome to Fun Sailing! Rick White has an excellent book available here in his on-line store, called "Catamaran Racing for the 90's" (Hey, time for a re-write Rick!) In it there is a whole chapter on spinnaker sailing.

This is probably the best web site for that kind of information, and as some have suggested, take it to any regatta, there will be other spinnaker cats there to show you how it's done. The Inter 20 can be a little intimidating at first because of the size and power, but once you figure it out, it is a great boat, it's fast and stable. Inverness is over by Tampa, is that right? There is a cat sailling group over there at Dunedin who could help you out. Or get to the Gulfport Yacht Club (St. Pete area) there are plenty of knowledgeable people there to help you.
