Sorry, I have to disagree. The skin is made of a very low stiffness material compared to wood or aluminum. It can not provide significant stiffness. There is some, just not very much.

: That's where the yield strength of the material comes into play.
: Higher yield strength means it can be flexed farther before it
: bends or breaks. The downside to high strength alloys and
: hardened materials is that they are typically more brittle, so
: they may break rather than bend. A balance needs to be stuck,
: based on the application.

: In other words, a boat is the sum of its parts and its strength is
: not defined by any one of them. It's also important to remember
: that the skin is a structural component and contributes to the
: overall strength and rigidity of a boat, not to mention its
: ability to float. ;-)
