Here some updates :
I think first Flyers built by AHPC were all carbon but their website now lists construction as carbon and kevlar. My guess is Greg Goodall is now using an outer kevlar skin for impact resistance and inner carbon skin for stiffness and strength.
Full kevlar hulls are produced significantly more lately. There are various reasons for that. That is all I can say at this moment.
Marstrom platform (epoxy pre-preg, Nomex core, autoclave cure) is probably the strongest construction. Others are vacuum bagged with the resin infusion system used on the A2.
AHPC has been using infusion for a while now. Nacra makes a big fuss about their boats being the first to use resin infusion (especially with the F18 infusion) but they are just wrong. Several other were already using this methode even in the F18 class.
