From the DIY perspective. The hulls don't seem to me a big deal. Certainly there can and will be more development and refinement that will take place. Lots of folks have the time and skills to build Blade hulls or Mozzie hulls or take your pick hulls and that cost will not vary too much.
The superwing mast is the stumbling block. I sail/race an old boat on a limited budget. I only look at the F16 forum as I would drive past the Porsche dealership, very slowly and only looking.
What possibly can be done to take the "bite" out of the mast cost? Is it that much a contributor to speed? Can a different (more common) extrusion be developed along with accompanying sail.
