Interesting how the team that gets to decide the design rules of the boat have an advantage!
To be fair, unless there’s a well hidden loophole they’re exploiting, then it’s the same rules for everyone.
It was more of an issue in previous campaigns where they would deliberately write rules to disadvantage teams they didn’t want to face (budget caps to keep high spenders away, high entry fees that kept small teams away, different numbers of prototypes allowed for challenger / defender, etc). And RYS/Ineos were the challenger of record, so were involved in the negotiations on the rules, location, etc. I didn’t keep up with the politics this time round but for AC36 ETNZ designed the mechanicals of the foils, while Prada as challenger did the foils themselves?
It’s not the pre J-class era when the defender could build a lightweight speed machine while the challenger had to sail to the race in an more sturdy offshore yacht. Or the IACC/12M eras when the winner was whoever won the preceding court case over who’s boat bent fewer rules.
