Clinker (boat building)
Clinker-built, also known as lapstrake-built, is a method of boat building in which the edges of longitudinal (lengthwise-running) hull planks overlap each other. The technique originated in Northern Europe, with the first known examples using metal fastenings that join overlapped planks in c. 310-320 AD. It was employed by the Anglo-Saxons, Frisians, and Scandinavians in the early middle ages, and later in the Basque shipbuilding region where the Newport medieval ship was built.
