Nacra has the 16square, I believe before they kill that class and enter the F16 market, which will happen one day but at the moment what will happen is the current 16sq. will be modernised, it will have a square top instead of the current pin head and a asmetrical spinaker added, still a 1 up cat, and in saying this I raced against one recently where the nacra people were and it had the spinaker conversion, it performed well and the changes would be inexpensive, so dont hold your breath, as for hobie, its a business and if they can make money then they will produce the goods, but it will be at cost of the hobie 16 and i cant see that happening, perhaps a upgrade to the existing models which would be cheap an worthwhile without killing the class, especially at the current ecenomic times
