I talked to a couple America's cup folks last year. I asked what technology from all their R&D was likely to
work it's way into general consumer sailing boats. His answer was the wing sail. I thought to myself, it would take years before someone figured out how to make them
work on a cruising cat. Perhap's it's been
solved?
