There were only two boats this year and in the past there were a lot more.![]()
I believe you are confusing the qualifier races with the actual cup races.
"From the first defense of the Cup in 1870 through the twentieth defense in 1967, there was always only one challenger. In 1970, for the first time, there were multiple challengers, so the NYYC agreed that the challengers could run a selection series with the winner becoming the official challenger and competing against the defender in the America's Cup match. Since 1983, Louis Vuitton has sponsored the Louis Vuitton Cup as a prize for the winner of the challenger selection series."
