Well, the FX-on in glass/vinylester/alu is current 145 kg in ready to sail attire (singlehanded mode no spi; see Texel measurements). Comparing apples to apples this must be compared to a plain glass/vinylester/alu F16 without jib gear and spi gear = 110 kg - 2 kg - 5 kg = 103 kg. That means that the CARBONE first needs to loose 145 kg - 103 kg = 42 kg = 93 lbs before it can even be lighter then an old tech F16. That is a whole lot of weight to loose even for a all-carbon boat.
The real weightsavings are to be found in improved laminate techniques and quality control systems. With those the old tech FX-one can already get down to 125 kg at the absolute minimum, probably a little bit more. If they weren't using those techiques before then why should they suddenly do it now ? Makes no sense.
Carbon in the rudders and daggerboard is pretty old school already, we all have these in the F18, F16 and A-cat class for some years now. Using carbon cloth there instead of glass is not saving alot of weight at least not in the same measure as proper laminate techniques can achieve. I don't see them save more then 7.5 kg on mast either (based on measured data I have on Tiger masts and F16 carbon masts and adding some margin). I know they are not going to save more then 2.5 kg per beam either. Some maybe we have reduced the weight by 15 kg now, that still means 27 kg have to come out of the hulls; 13.5 kg per hull. Currently the FX-one hulls are above 35 kg a piece. Minus 13.5 kg puts them at 21.5 kg per hull if only they are achieve parity with a plain old tech F16. Currently the best F16 hulls are 22-23 kg per hull and we needed some proper laminate techniques to get that low. No, exchanging the glass matts for carbon matts is not going to make the CARBONE lighter then an old tech F16. They'll need more improvements, mostly in the area of laminate techniques to get to the optimal fibre to resin ratio. And they'll need to loose those heavy alu rudderstocks, that heavy Hobie snuffer and other things.
Another point of note is this. In Europe an FX-one in current build (145 kg old tech) costs 16.000 Euro's without a jib kit. Old tech F16's go for 14.000 or less when the cost for the jib kit is removed from the quote. The CARBONE is not going to be cheaper then the current FX-one due to the extensive use of carbon. A modern TOOL A-cat can be had overhere for 17.500 Euro's, so that CARBONE must take care not to inferiour in performance to an A-cat and be more expensive at the same time. Of course you'll get a fine MacT-shirt ehhh, Hobie T-shirt with that purchase but that's a 10 buck item.
I'll be very interested to see the final specs and quote for this CARBONE
