Hello Rolf,
Carbon is not magic. A carbon mast alone is not faster than an aluminum mast. The only way that a carbon mast or any carbon part can make a sailboat faster is by reducing weight. The weight savings due to a carbon mast in the case of the Tornado class is going to be small because the aluminum Tornado mast has already had every excess ounce of weight squeezed out of it. Also to realize any weight savings due to a carbon mast in the Tornado class, the class rules, minimum all up weight, must be changed. If the minimum all up weight is not changed, it will be very difficult to find any boat speed improvement at all. Also any different material mast, especially carbon, will have a different mast bend characteristic under sailing loads. Then the boat will have to be reoptimized and new sails, diferent luff curve etc, will have to be determined. This will take a year or two to work out and many many suits of experimental sails, many dollars spent.
The Olympic Tornado is already faster than any other 20ft boat so why induce this major upheaval in mast rigging and sails for a maybe 0.001 reduction in PN?
