If the Class/build manual require approval of a build change or process - and that change wasn’t asked for or approved prior to construction - then the Class, however flawed, made the correct decision. It sucks, but how could they have done otherwise without destroying the Class with something so public? Matt is a good guy and his company does good things for sailing without a doubt, but the Class had no choice.
To the point of other manufacturers doing the same thing, or mold issues, or mast specs, or rudders - take pictures, do core samples, draw exhibits of what has changed. Then bring the evidence to the Class. If they did the right thing here, they should continue to do the right thing. If they don’t, this community on this site will kick up a bunch of dust, I’m sure of it.
That’s how this one design thing works. if there is proof a boat or a series of boats is in willful noncompliance after inspection and a transparent process, pull the plaques of the boats that are in non-compliance, make the manufacturer buy back the boats, and enter into an identification process by which the manufacturer can see the boats for non-competition use with some sort of scarlet letter to ensure they don’t pop back up again.
That’s after one proven issue. If it happens again - take a chainsaw to every boat in non-compliance. Every single one. I promise you if a builder knows that’s what will happen after the first strike, there won’t be a second.
These are C420s. This is the last class that should become the Wild West. They are not high tech - they aren’t supposed to be - and anyone chasing a “faster” boat really needs to get a grip and step up to an i420 or a 29er or a Nacra 15 where the tech aspect of the classes are understood and we all know it and accept it.
Follow the rules - build AND process. That’s how to get through this and keep this cool grassroots class on track.
