4.3 Contains the relevant allow modification to legacy jibs, 85% has to remain "unmodified". Of interest is also 4.14 which states they can build 5 new legacy jibs, but that doesn't apply anything to the repairs, just interesting in terms of limits.
Not necessarily, any legacy jib can be modified up to 15% (e.g. 85% is immutable) but this repair doesn't necessarily count as a modification because of 4.28:
They are restricted on new foils yes, but "boat zero" is allowed to use various "legacy" components that have a different allotment provided those legacy components are as they were measured in for AC36.
It was a measured in part of the original boat, and theres nothing in the rules excluding it from the definitions of a legacy AC72 so at least my armchair guess is that removing it would count towards the percentage of modification allowed.
I don't think there is anything preventing you measuring an old boat as a new boat, it would just be your one AC72, so the value is in the jump start to get sailing in the 20? extra days your given, so limiting the boat to mostly AC36 configuration in my eyes sort of makes sense, as an equaliser...
Further rule prevents new foils:
Plus this may prevent removing the backstays?:
For the cyclors vs grinders, maybe the structure simply wasn't able to be altered in a way to may room for cyclors? (or prehaps just required more modification percentage than permitted?) Or maybe Alinghi thinks...
The teams provide / appoint someone to the "Recon Management Panel" under the rules of the technical regulations to manage the shared recon.
I only had a quick read of the TR but my understanding is that any legacy (from AC36) component must have a version A that is in a measured...
No idea, but I could see just sticking it on a container ship, not like it'd fit in a container if dissassembled anyway. If they did dissmantle it and reasemble it prehaps it was simply that there was no space to reassamble at hq, its on a lake afterall.
No there is a constructed in country rule currently in force from the protocol, it applies to the hull so it depends on wether the foils are included with that, the foil arms are not as they are one design.
