The last meaningful America's Cup races were held in the late '80s. Somebody squinted hard enough at the 12-meter rules and entered a multi-hull. Now it's just a matter of who spends the most money on a carbon fiber boat with a wing sail. This is a sailing race of fundamentally unseaworthy vessels. It would be literally be safer to cross an ocean in a dinghy than in one of these monstrosities.
Come September, do yourself a favor. Watch Deep Water on Netflix. Read any book on Ernest Shackleton. Read any Lin and Larry Pardey book. You'll finish all three before the America's Cup race is over, and you'll know more about sailing than watching every second of the America's Cup races.
