What are ship's hulls made out of?

Ship hulls are typically made from a variety of materials, including steel, aluminum, fiberglass, and wood. Steel is commonly used for large vessels due to its strength and durability, while aluminum is favored for smaller crafts because it is lightweight and resistant to corrosion. Fiberglass is popular for recreational boats due to its ease of maintenance and versatility. Wood, though less common in modern shipbuilding, is still used for traditional boats and can provide aesthetic appeal.
