I fall on the "go for it" side with Mary.
Some reasons:
This is one person spending thousands of dollars to improve on a boat design which is already very advanced.
He is funding the developement that the companies and normal people can't.
The Class seems well organized and could quickly outlaw anything which causes problems(the iF18 Class outlawed canted daggerboards).

Tad, in light boats, weight is critical. A sailor can't be sure that he will have a good start or pick the correct side of the course, but he can make sure that the boat is as efficient (light, smooth, clean) as possible. Most A Class boats come from the factory about 5 lbs underweight to allow the owner to bring it up to EXACTLY 165.0lbs.
