Say what you will about sailing being a rich man's sport, and put aside those visions of Buffy and Lance sipping martinis whilst peacocking in whale-and-lobster embroidered Vineyard Vines gear, because when you get right down to brass tacks, we're talking about a sport in which amazing machines guided by amazing humans harness the winds. Real, true man-against-nature-against-man stuff. Reaching potential top speeds of over 50 miles per hour, which may not sound all that fast until you're in the open ocean with little to no cover, salt spray stinging your face and your whole boat -- weighing in excess of 13,000 pounds -- lifted out of the water on a skinny hydrofoil, the whole thing balanced between victory and utter destruction by hundreds of hairs-breadth calculations and adjustments that must be made literally on the fly, it's as riveting to watch as any Tour de France or Daytona 500.
