Abstract: An integral floating cooler structure including a barge member having a barge bottom and barge sides with a storage chest having a chest bottom formed in common with the barge bottom, and chest sides of less thickness that the barge sides and having lower portions formed in common with the barge sides. The chest bottom and said chest sides are of thickness sufficient to provide thermal insulation. The barge bottom and the barge sides are displacement volume sufficient to provide buoyancy for the cooler structure. The exterior surfaces of the chest sides; the barge sides and the barge bottom forms a common exterior surface for the cooler structure. The interior surface of the chest bottom and the chest sides forms a common interior surface for the cooler structure.
