From the mid seventy's untill the early '90's we manufactured and sold literally thousands of 14' cats predominately in South Australia. On one of our designs, the Alpha Omega 4.4, which was set up from the factory as a one up on trapeze racing cat, cat rigged, we rigged several with a spinnaker as well. Sailed either one up or with a crew in that configuration ie cat rigged with spinnaker (and an extra trapeze for the crew) it was a truly exciting racing experience. It all worked very well, and the only thing agains it at that time was that there was a lot of resistance from the sailing community. At that time the most common opinion expressed was that "skinnakers belong on mono hulls not on cats". This, even from the cat sailors! It would appear that the general opinion has changed some what with the success of the formula 18's?
