Planks were made watertight primarily through the use of caulking materials, such as oakum (hemp or jute fibers soaked in tar) or pitch, which were driven into the seams between the planks. Additionally, wood was often treated with oils or sealants to enhance its water resistance. In some cases, the planks were also joined using techniques like edge beveling or tongue-and-groove joints to minimize gaps. These methods collectively helped ensure that vessels could withstand exposure to water without leaking.
