Carvel, in which a smooth hull is formed by fastening flush-fitting planks to underlying frame s. The planks may be curved in cross section like barrel staves.

These fastenings typically go through a metal rove over which the protruding end of the nail is deformed in a process comparable to riveting the planks together. This gives a distinctive ...
