Kent, get "Catamaran Racing for the 90's" available at the Cat Sailor store on this site. It goes in to great detail on the finer points of cat racing, main trimming, spin. work, etc. and has a whole chapter on the Hobie 16.
Rick if you are reading this, is there going to be a "Volume II, Catamaran Racing the Spnnaker Cat, A cat, F-18" etc. coming out any time soon?
I would love to get all of the accumulated knowledge of Spin cats and A cats, from Randy, Alex, Nigel, John, Charly, Mitch, Haken, Melvin, etc. (today's spinnaker cat and A cat top tallent) , down on paper for the rest of us.
