Some things are too expensive even for the America’s Cup series. In 2013 they were racing 72 foot-long, hydrofoil catamarans. They were expensive to build, hard to control, and it seems they were suppressing the competition. So for the 2017 series, they went to smaller foiling catamarans. (40 or 42 feet, I can’t remember.) For 2021 they will be using foiling monohulls.
But the AC72 was a magnificent machine. (When YouTube freaks out over the privacy extensions in your browser, use that link above.)
Andrew “Bart” Simpson was killed May 9, 2013 during an AC72 training run. He was on Team Artemis.
