Yawl

The hull of a yawl was usually constructed so that the lower edge of every plank in its sides over-laid the upper edge of the plank immediately below. This way of constructing the sides of a boat was called clink-work, and often craft built in this way were described as being clinker-built.

In his detailed study of the Endeavour, Ray Parkin has estimated that the Yawl carried on Cook's first expedition was about 3 metres long by 1.5 metres wide and 0.7 at the sternpost.
