Wooden bones

The boat's framework will be made of "ribs", and a keel that will be the "spinal column". Differently than bones, ribs and keel must be connected to be rigid, to avoid that the boat will be deformed or shattered by the forces encountered at sea.
But at the same time, stiffness must not be stronger than resistance of her materials: in a classic boat, different woods, with different resistance or elasticity.

Taking advantage of shapes and veins of the wood, cut and joint following lines and hollows as done for centuries, the parts of the framework become a wholesome, a machine built to meet forces and loads that will stress it from every direction, and resist and react with resistance and flexibility, stronger than any single piece.
