I do laugh when I hear talk of ETNZ "cheating" by designing a foiling AC72. Nor have the found a "loophole" in the rule.
What they have done is designed, perhaps the only "safe" (and I do say this with a grain of salt) AC72, to a design rule the OC, as cup holders have formulated.
It's safe, its fast and it was designed within the rules.
Now I understand that there is an argument to change the rules to enhance safety and i'm sure there's a number of ways this could be done.
However the facts remain the same - ETNZ and LR can foil fast, safely and within the rules, whereas OR have shown some unsteadiness foiling, Artemis have not really shown anything apart from a Cayard size cluster fuck!
This is a net result of design choices. Nothing more and nothing less.
Why we have to change design rules to suit those that have made poor choices, i'll never know. If they were really serious about safety and perhaps less wing area as Cayard noted, why don't they trim 2m off the top of their existing wings? As far as I can tell, this is totally within existing spar limits, would satisfy the safety aspect they so vocally now need and also negate the need for absurd and unprecedented changes to class rules as the last minute..
The current farce is nuts! I also don't believe for one minute that IM is as independant as everyone makes him out to be.
