Kevin,
A boat or anything for that matter is only worth what someone will pay for it.
There is always someone out there who thinks they can build a better mouse trap, good on you for shelling out the cash to build a Carbon T, but the main reason why the class has remained so strong for so long is that any decisions regarding changes to the boat have to approved by 2/3 of the class members. these changes are invariably for the good of the class. what does the class gain from making all the current boats obsolete? the competitive life of a Marstrom T is more than 10 years, so by throwing them out what do we gain..
Marstrom has made a carbon T, more for kicks than anything. He understands that the class is great just as it is and the only change on the cards is the possible switch to a carbon mast. the case for this is much better then changing the hulls. The alloy masts are hard to produce in consistent quality and they are very labour intensive (putting the taper in) Marstrom could produce carbon masts for about the same price as an alloy one and the change over prive is only a couple of grand, much cheaper than a new platform.
If you want to make carbon T's then get too it, but dont have a shot at a class that has been the leader in catamaran development for the last 30 years.
in fact why do you use the T hull shape? there are plenty of faster hull shapes around now, why not make a carbon M20? oh thats right they already make one...
