RE: NP forum
Regarding the mast extender concept, I can't claim to know who originated the idea, but I can say that it isn't a new idea. I know that Bill Hansen, formerly the founder and designer of Windwing Sails, was offering fixed length 40 and 60cm mast extenders in his line of branded products in 1998, as I verified it a published Windwing brochure for that year.
Actually, when you go back and review history, you will find that Bill Hansen was a serious innovator that advanced many sound ideas. Often I don't think he gets the credit that he really deserves.
