How did 15th century sailors carry water?

In the 15th century, sailors typically carried water in large wooden casks or barrels, which were sealed to minimize leakage and contamination. These barrels were often made from oak, a durable wood that helped preserve the water's quality during long voyages. To ensure a continuous supply, sailors would refill their barrels at ports or freshwater sources along the way. Additionally, they sometimes used leather water bags, though these were less common due to the risk of leakage and deterioration.
