Right... 4 videos... one of the equipment fail that almost resulted in a capsize... the equivalent of a bad wrap on your spin sheet in a monhull leading to a broach.
Not a half baked design issue... (that you agree with me on actually)

The second vid is of a stuff which slowed the boat..... IE a racing Fail... not a boat that was over matched by the conditions and going to crash... (granted they had legislated that possibility out of the race)

And of course the design failures that happened before the racing.

Don't take my point to an absurdity... the boats are supposed to be exciting and challenging... They just should not have correctable bad manners because the Administrators of the game made some bad choices.

Finally you can't compare the AC which is a design and racing, push it to the limit competition with OLYMPIC Competition in strict one design boats.... The entire POINT of the olympics is to medal multihull sailors on their demonstrated sailing skill... not luck or boat design.
