Clinker (boat building)
Clinker boat building is a method of constructing hulls for boats and ships by fixing wooden planks to a frame so that the planks overlap each other gaining support from the frame and from adjacent planks. The technique was first used by the Vikings.
Narrow planks are fixed to a frame of "ribs" which are first mounted on a heavy keel. The downward edge of each plank overlaps the plank below it. The overlapping edges are bevelled to create a tight fit. The overlaps generally taper to nothing at the ends of the boats.
The planks are fastened together in several ways:
- with copper rivets consisting of a square nail and a dish shaped washer called a rove
- with iron nails with the protruding ends bent over and back into the wood in a technique called clenching . Clench built is another term for this technique.
- adhesive, notably epoxy
Clinker boats are known for their lightness and flexibility.
