I own an older C&C but have not sailed on the newer ones. Like other fast boats, they are light. But I'm not sure I would be concerned that they would be that easily damaged. I have a cored hull from 1979 and have no complaints about its durability.
The new C&Cs have received great reviews. At least one of them (the 115?) has won boat of the year from Cruising World. They are now built by Tartan. Again, haven't sailed on them but word of mouth is very good.
