I'd like the insight of the layup experts on this board. In a composite boat, is a little bit of hull flex a good thing? Or is absolute stiffness the desired goal in boat building?
I have four different fiberglass boats, all with varying degrees of stiffness. One boat surprised me with the amount of flex in the hull, but has shown itself to be extremely durable through several years of paddling. For example, I once sidesurfed it into a beach with mixed sand and rock, and the hull rippled over every rock. There was absolutely no damage I could see inside or out.
In contrast, I also have a heavier, stiffer boat. While I haven't tried to replicate the experiment above, I wonder if its stiffness would make it more prone to holing.
Any thoughts from the experienced fiberglassers?
