The clip you showed of a foiling cat being towed in 'tank-mode' testing from above the deck and at an angle, was that footage from TNZ before they sprung the foiling AC72 for AC34 in SF?I was critical of INEOS last cup for not thinking outside the box enough (but they had some glimer of good avenues), and even more so in Bermuda. So, I think ideas like this are getting traction in the team is a positive.
However... if they have just thrown away a month's sailing with a concept that they weren't certain would be allowed, then that's a bit of a fuck up. They could have developed this in the background.
Obviously we don't know that's the case, maybe these delays are unrelated to any planned periods of tow testing with this tow mast (post?!)
Am guessing there were no rules to argue against it back then but it is obviously a smart approach. Again, am hoping this 'tow mast' challenge gets thrown out but am not predicting it.
