Main Page | See live article | Alphabetical index The clinker-building style of ship (or boat) hull construction first came into use by Vikings. Narrow planks are nailed to a frame of "ribs" which are first mounted on a heavy keel. The downward edge of each plank overlaps the plank below it. Clinker-building was used in Europe and the Americas for centuries, even after the development of the more efficient caravel style. This article is from Wikipedia.
