I work in Ship Builder america had many forests. The English began ordering ships built in the colonies because wood was chap there. It took at least at year to build a ship. Lives depended upon the ship builder’s skills. The caulk was made of tar and oak urn, a ropy fiber made from oak trees. ships linked them to the world a allowed the colonists to trade. They had to be perfectly shaped to create the hull. It was hard back than. But we manage to git there and had enough of wood to make a lot of ships. Today ships have different materials, but they are not called ships they are called boats. It is hard work for me you got to life up heavy wood.
