The construction of a ship is a long and complicated process. It starts with the steel, which is baked in an oven until it is red-hot and then cooled down with water. The steel is then cut into the appropriate size and shaped with a cutting torch. The next step is to cut the holes for the watertight compartments and the boat’s machinery. The steel is then welded together to form a hull, which is where the ship’s weight is distributed. A ship is usually built upside down so that it can be flipped once it is finished. The ship’s design is then applied to the hull, and the ship is painted and given the finishing touches.
