"Are there any new technologies in Kite Boarding or Windsurfing that we may eventually see in our cat sails?"

Reworded : Will we see windsurfer rig technology on catamarans with wide luff sleeves, camber inducers and fibreglass/carbon masts graded for stiffness to suit the sail cut and provide the automatic leech twist-off we are looking for, and if so, how soon ?

Last question : Why are catamaran sails and masts so much more expensive than the windsurfer rigs that are 20 years ahead ?
