In some shipwrecks we can recognize factors such as units of measurement, use of segments and arcs, and repetition of shapes, which may have been rationalised during the transition from craft shipbuilding to a formal design process. This is an a posteriori assessment, as we do not know how hull-shapes were planned and controlled in Antiquity. However the Cheops boat, and the Madrague de Giens, Anse des Laurons II, Fiumicino 4 and Yassi Ada II wrecks, display measurements and geometries suggesting rational approaches to hull-moulding, with principles common to those of medieval and Renaissance shipbuilding and the traditional Mediterranean garbi.
