I actually would like that to happen. The novelty of the foiling boats quickly got old. There were very, very few exciting moments... the USA team flipping their boat in the Challenger round robin is one. But otherwise, all you saw was one or two guys running across the deck after a turn. NO CREW WORK at ALL. Just the top of some dudes pumping away on invisible coffee grinders. A boat comes off it's foil and loses a mile, then makes it up on the next leg because the other boat came off it's foil and ends up winning the race by a mile... WTF?
Speed is relative.... two equal boat in a tacking duel making 10kts upwind in 20kts of breeze with water sloshing over the deck and crew working hard looks really, really fast. Two foiling boats making 35 kts in the same breeze with no apparent activity other than the guy driving looking around a bit.... uh... what's the fun in that?
What some of these guy are missing is that it's not absolute speed that sailboat racing fans enjoy, what they like is competition, strategy, execution, etc. When you think of the excitement of auto racing.. what is it you remember? The speedometer readout. nah... you think of the crew work in the pits, the drama at critical turns, the strategy each driver uses to pass the car ahead, or to keep from being passed.
I would rather watch a fleet of Aussie 18ft skiffs race any day of the week that a freaky looking, no personality AC foiler just trying to keep its hull from touching water.
