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.
Not so....
You will be able to
design the mast bend characteristic(s) you require as the carbon can be layed up as required (eg more carbon wher fittings attach and less where there is little stress.
