Wood: The Skeleton andSkin of the Ship

Wood constituted thee submitming majority of a vessel 's mass, but shipbuilders did not t simple choose any timber. They selected species based on thee specific mechanical demands of each contrigent. Oak (Quercus robur) Wu 'te most prized species, favoret for its extraordinary equith, natural resistance to o rot, and thee ability to be slit radially into long, prostt planks following the e grain.

Other species were selected for their specific properties:
