The idea is that the Wave Carbon boards should be as strong. Lighter but with stronger materials so therefor more expensive. So its more weight vs money than weight vs strength.
But in practice there is no way of _really_ knowing, I would say. I've put mine though some hard sailing, on the rocks, collisions and stuff, and it handles that well. And of course a lot of strength testing have een done before production. But the wood dur-x constructions is _proven_ for many years with very, very low warranty rates. So if durability is your no 1 priority I think it is a wiser decision to go with wood.
