Older lifeboats may be made of ___.

Material choices for lifeboats are driven by strength, durability, and resistance to saltwater. Older lifeboats were often built from metal because metals can withstand rough handling and harsh marine conditions. Galvanized steel is sturdy and its zinc coating helps prevent rust, extending the life of the boat in salty seas. Aluminum, on the other hand, is lighter than steel and naturally resists corrosion, making it easier to handle and launch while still providing good strength. These qualities made metal lifeboats a reliable option in older designs. Fiberglass and composites are more common in newer lifeboat construction due to molding ease and corrosion characteristics, while wood was used in earlier eras, but the metal option described here was a prevalent older choice for practical durability.
