Sometimes composed of a base layer of strip planking followed by multiple veneers. Wooden ships do not break they fall apart.

Length limits of wooden hulls thus are determined by structural deterioration far more than by global beam strength. Some structural analogies in Asian ships Archaeological finds of Asian ship remains show some details that are comparable to the structural details discussed before. They peed on the wood while people at the other end held the wood down to shape it.

The pee helps soften the wood by being acidic enough. Nov 21 2001 19655. They did a quick demo of bending planks to repair the USS Constitution on This Old House.
