Multi-rig racing

nope- made with 'intangible' benefits like running a innovative sail loft staffed with professional sailors who are paid to offer support (and possibly even coaching and training if you ask nicely). Much of this progressive development then transferring into less popular classes and new products- like both the Zero and Aero which uses the same parent company.  So everyone in sailing can benefit if they choose too.

But it's not a price point for everyone, which is why the Solo is a great class model-  it still allows smaller lofts to get involved and offer cheaper alternatives across the value : performance spectrum.  

I doubt there are too many folks would really call Solo sailing 'chequebook sailing', not in comparison to other single handers out there- it seems a well balanced class at every participation level from what I've seen.
