A U.S. Navy wooden water cask from the World War I era was a vital piece of lifeboat equipment, designed to store fresh drinking water for survival at sea. Typically made of oak or other durable hardwoods, these casks were coopered with iron bands and sealed tightly to prevent leakage or contamination. Compact and cylindrical, they were stowed securely in lifeboats and often marked with capacity and naval identification. Their rugged construction and simple design reflected the practical needs of wartime maritime safety.
