Clinker (boat building)
（重定向自Clinker built）
Clinker built (also known as lapstrake) is a method of boat building where the edges of hull planks overlap, called a "land" or "landing." In craft of any size planks are also joined end to end into a strake. The technique developed in northern Europe and was successfully used by the Norsemen and typical for the Hanseatic cog. A contrasting method, where plank edges are butted smoothly seam to seam, is known as carvel construction.
