Watertightness |
|
|
Boats must also be watertight—that is, invulnerable to leakage through the joints of adjoining pieces. Boatbuilders made wood plank boats watertight by caulking between planks with fiber threads, pitch, or a combination of these materials. For boats of skin or bark, filling interstices with pitch was common practice. The contemporary practice of molding a hull eliminates the problem entirely. Without seams there is no possibility of leakage. |
