We built an all carbon F14 Aldo basically because we wanted to and we could! It also solved a "supply" problem with cost for small quantities of aluminium for beams and masts for what we originally considered an experimental design. Prior to the all carbon F14 we built a standard "one off" FRP 14' (but without spinnaker) with Aluminium beams and mast - the aluminium was the last of very old stock that we had in house. The weight difference between the carbon F14 and the FRP 14 was only14Kg's
So the difference between the old school boat and the carbon wonder f14 is around 18%. I hope you can see the irony in your figures.
