They did not add the spin option to the boat
Actually they did - the New England guys created their specs with the spinnaker and asked Performance Cat to adopt it and make it an option on the boat. Perf did adopt a spinnaker option for the 6.0NA but they went their own way ignoring the work done by the New England group. I don't know of anyone that ever purchased the factory spinnaker option on the 6.0.
