Speaking as a sailor who moved from a 70's Nacra to a 00's Blade I was surprised at how 'tender' the hulls are. I think I already had a dent before the boat had hit the water. After a couple of capsizes, the insides of the hulls are starting to resemble golf balls, with elbow and knee dents.
My boat isn't Kevlar. Kevlar may be something to look for.
