We already do build a Blade to minimum weight and at the same price (retail) as quoted by Marcus. We also use a large percentage of carbon and Kevlar (one – soon to be two - with a carbon mast as well as the standard carbon rudders and centre boards - not primarily for weight saving - but for strength and longevity of the boat, in fact the material cost difference between carbon, Kevlar and “standard” fibre glass is not a great percentage of the overall costs of the boat, the main costs are in build time (labour) and Macca, to the contrary, my "argument” is solid for the allowance of the use of ANY materials that an owner desires with no detriment to the "class/formula". Why should anything be banned when it/they have no detrimental effects to the class? If you start banning simply for the sake of banning for some “airy fairy, perceived, maybe” scenario it opens the floodgates and you are treading a very slippery slope. Your “argument” is not based on any fact within the class. If and when the things that you pose should happen, surely then is the time to take the required action, to do as you say now would only damage the growth of the class and I assume that is not the reason for your posturising?
