Hi all,
as suggested I would agree that Kevlar makes no difference when it comes to dents, the amount of denting that occurs in a Glass or Kevlar outer skin is a result of the core stiffness, as was said, solid glass boats had little trouble with this but they are to heavy and flexible for a F16 hull.
So the amount of denting is reliant on the density of the foam core on boats like Taipans and Blades and then it is still a balancing act between weight and dent resistance,along with thickness for overall stiffness. I have certainly seen some Mosquito's in OZ that dent to easily. Can not comment on those in the US, it may be worth asking the manafacturer if he has altered foam core density at all, as that is what they did with the Mossies in OZ.
