I suggest you find a class that welcomes such keel development and go and prove your weight theory. Then try to sell it. Love it or hate it the F18 formula has proved extremely successful in developing class racing around the globe. Lightweight boats of various sizes have been built. There are obvious advantages to the singlehanded sailor which is where the F16 and A-class find favour. The M20 has proved to be a capable boat, at a price. The f18HT??????
If the F18 were to change and reduce the weight of the hulls and allow a carbon mast what would be the result? A substantial number of boats no longer being competitive and depreciating heavily, sailors leaving the fleet due to cost of upgrade and basically no longer being a competitive crew weight. Costs are contained when there is volume. You only have to look at the N20 mast issue to see what happens when low volume effects product viability.
If you want to 'develop' catamarans you need to be able to prove the benefits to sailors otherwise the idea is dead. With the advent of numerous high-performance skiff dinghies catamarans have changed considerably over the last 20 years. Racing cats are now almost universally spinnaker equipped and use daggerboards. That is development, and has been accepted. Don't knock what works. You do a disservice to people that have worked hard to develop the sport. Maybe the boat weight issue can be addressed by adjustable beam but until someone can prove it who will buy into it. Even then it may end up being a 'good but never made it' boat.
